I decided to prepare a separate article in which I will tell in detail and show with an example how to connect a TV to a regular desktop computer with using HDMI cable. The topic is relevant, and I often get asked about it. In fact, nothing is difficult. But there are some nuances that we will try to understand in the framework of this article.
Almost every, not even the newest TV, has at least one HDMI input. And in the computer, on the back panel system block there is HDMI output. This means that we can easily connect a PC to a TV using a regular HDMI cable, which you can probably buy in every digital equipment store.
Why connect them? Everything is very simple. TV can work as a monitor. That is, you can display an image from a computer on a TV screen. The TV can be used as the main monitor or as a second monitor. This means that the image from the PC will be displayed on the screen of a conventional monitor and TV at the same time. Or just on TV. It already depends on your tasks. It should be noted that HDMI outputs not only the image, but also the sound.
I myself, and other users, most often connect a PC to a TV to watch movies on the big screen, or to play games. You can also connect a gamepad to your computer and play on the big screen. Some people use TVs instead of monitors. They work with documents, surf the Internet, etc. But it seems to me that this is not very convenient. Yes, and the eyes get tired faster. For permanent job it is better to use a monitor at the computer. And connect the TV to watch movies, photos, games, etc.
The connection process will be the same for TVs different manufacturers: LG, Samsung, Sony, Philips, Panasonic, Ergo, Hitachi, etc. Just like there will be no strong differences in Windows settings. Yes, the settings in Windows 10, Windows 8, Windows 7 are slightly different, but not critical. I'll show you everything.
If you have a laptop, then you can do everything according to this article:.
Preparation: check the HDMI ports on the TV and computer, select the cable
First we need to check if our devices have required ports. We also need an HDMI cable to connect. Let's look at everything in more detail. If you have everything, then you can go directly to the connection and configuration.
If you have ports on both devices and have a cable, then you can connect.
Connect TV to computer with HDMI cable
Simply take a cable, plug it into the HDMI output on the computer and the HDMI input on the TV.
Important! Devices need to be connected when they are turned off and the power is off. There is a risk of burning ports. There are such cases.
If you connect the TV as a monitor, that is, the only screen, then the circuit will look something like this:
Let's also consider another case when a TV and a monitor are connected at the same time.
TV as a second monitor for PC
The monitor can also be connected via HDMI (like mine in the photo below), DVI, or even VGA. As a result, two screens will be connected to the PC.
We figured out the connection. Most likely, in your case there will already be a system unit with a monitor connected to it. And all you need to do is connect a TV to it.
Select HDMI input as signal source in TV settings
Most often, after connecting and turning on devices, there is no image on the TV. There will be an inscription like "No signal", "No signal source selected" or something like that. On the TV, you need to select the signal source. The port where we connected the cable.
To do this, your TV remote must have separate button"SOURCES", or "INPUT".
After clicking on it, a menu should open in which you can select the signal source. You can see which port on the TV you connected the cable to (each port has its own number). Or just select an active source. The process itself may differ depending on the TV. I have an old LG.
The image from the computer should appear on the TV. It will be either a copy of what is displayed on the monitor (if any), or a blank desktop (expand).
The main thing is that the picture from the computer appeared on the TV screen. Further, in the Windows settings, we can already change the image output mode. There are several of them.
Setting up an HDMI-connected TV in Windows
Screen resolution in most cases adjusts automatically. So in the Windows settings, we can only change the mode of operation with multiple displays. This is only relevant when a monitor and TV are connected to the PC. If there is only one display, then these settings are not needed.
The easiest way to change the mode in Windows 10, Windows 8 and Windows 7 is a keyboard shortcut Win+P.
After clicking on them, the "Project" menu will appear. In ten it looks like this:
On Windows 7 like this:
Let's look at each mode in more detail.
In most cases, these settings are sufficient.
Additional screen options
To open them, just click right click mouse over an empty area of the desktop. In Windows 10, you need to select "Display Settings", and in Windows 7 - "Screen Resolution".
A window with settings will open, where you can see how many screens are connected to the computer.
You can also define them (by clicking on the "Define" button), change the resolution of each screen and operation mode (which I mentioned above).
In Windows 7, the settings of a TV connected via HDMI look like this:
We figured out the image settings on the computer.
What to do if the sound from the computer does not go to the TV?
This happens very often. The picture appeared on the TV, but there was no sound. It is not there at all, or it sounds from the connected to the computer speaker system. If you want the sound to go through the TV, then first check if the sound on the TV is muted or twisted.
Your TV should be in the list of devices. You need to right-click on it and set "Use as default".
If the TV is not in the list, then right-click on an empty area and check the boxes next to two items: "Show disconnected devices" and "Show disconnected devices".
If this does not help, and there is still no sound from the PC on the TV, then try reinstalling the video card driver. Just download it and run the installation. Let the HDMI cable be connected to the computer at this moment.
How to check these settings in Windows 7, I showed in the article. Be sure to watch it and read the comments. There is a lot of useful information there.
I've never had a problem with HDMI audio output. How many connected, everything worked immediately after connection. But there is such a problem.
Connecting a 4k TV to a computer. Ultra HD over HDMI
If you have an Ultra HD TV (aka 4k) and your video card supports this resolution, then there is a chance to get a beautiful and clear image. I checked, everything works. I have a Philips 4K TV. And in the computer video card GeForce GTX 750Ti which supports resolutions up to 4096x2160.
There are a lot of nuances there. I'm not a gamer, so I'll try to explain as best I can. The fact is that you can output a 4k image via HDMI, and I did it. But most likely we will get a frame rate of 30 Hz. Which is very little. To get 60Hz, we need a video card with HDMI 2.0 and the same cable. That is why DVI cables are used to connect to 4k monitors. And I haven’t seen anything on DVI TVs.
I connected everything, started the computer, and saw that the image on the TV was some kind of strange, wrong colors. Maybe it's just in my case.
Everything is solved very simply. First, I tried to disable UHD (Ultra HD) in the TV settings for the HDMI port to which the PC is connected. The image became normal, but the resolution turned out to be normal, 1920x1080. Therefore, this method is not very suitable for us.
To get a real 4k image with natural colors, you just need to change the screen resolution to the maximum 3840x2160 in the display properties in Windows 10.
The image immediately returned to normal. The scale was automatically set to 300%. Otherwise everything would be very small. It can be changed if necessary. I have not tried to play at this resolution. But I don't think it's realistic. Moreover, the video card on my computer is not the newest and not the most powerful.
I look forward to your comments. Ask questions and don't forget to share your tips. Good luck!
It is almost impossible to find televisions with a kinescope in our apartments. The electro-ray tube has been replaced by plasmas and liquid-crystal screens. These TVs are built using digital technology. Transfer from analog signal to digital greatly simplified the process of connecting and combining different kind devices with each other.
Connecting a TV to a computer allows you to refuse common antenna. On the big screen you can watch any videos, clips and photos. And the power modern computer allow you to transmit a signal to both the TV and the main display.
TV can be used as a multimedia center
There are several ways to connect a TV to a computer as a monitor. You can do without wires, and the process itself is not difficult. You can easily turn your TV into a modern multimedia center.
How to connect a TV to a computer?
The connection method depends on the availability of certain connectors on the TV and computer. There are three connection options:
- With cable. The TV receiver can support the following interfaces: HDMI, DisplayPort, DVI or VGA. The first two are digital, the third is integrated, two types of signal can be transmitted through it. VGA is a pure analog interface.
- Connection via wireless technology WiFi. In this case, you need a router, and the TV must be equipped with a WiFi module. Not all TV receivers have it, but the module can be purchased separately from the store.
WiFi module for wireless connection
- Connect your computer and TV with an Ethernet cable. RJ-45 connector is used for connection. The cable is also called twisted pair.
A router is a special network minicomputer that allows you to combine different architectures local networks. Its task is to distribute information packets according to certain rules between different recipients: laptops, tablets and other devices connected to the network.
The operating system on the computer allows you to connect without much difficulty. She will offer best option. Connecting via WiFi in most cases takes place automatically. It is only necessary to approve the proposed method.
HDMI and DisplayPort
These two interfaces are currently competitors. They transmit sound and image digitally. To connect to a PC, choose a connecting cable based on the connectors that are present on computer video card and TV. It doesn't matter if the output of the computer is a DisplayPort connector, and the TV has HDMI. The electronics store has cables with the necessary adapters.
Cable connection methods
DVI and VGA
The VGA interface uses an analog signal. If you are planning to use VGA connector, then you need to stock up on a cable that has a DVI-VGA adapter. In this case, the signal is converted to analog. Doing a reverse conversion does not make sense, there will be big loss of quality.
Connectors for cable connection
Digital interfaces are combined without problems. On the counter of a specialized store you can find adapters of all types.
Wireless connection
You will need a router to connect via WiFi. To it, in addition to the TV, it is possible to connect a large number of devices: tablet, smartphone, laptop. The main advantage is the absence of a bundle of wires stretched around the apartment. Only one wire is needed, which provides access to the Internet.
Create a network using a router (router)
To distribute access to the network, the router is pre-configured. As a rule, the provider provides detailed instructions to set up or you can invite a representative of the company. A specialist will help you connect and set everything up. If everything is done correctly, the computer will automatically detect the network and automatically connect to it. The TV must be connected manually, through the setup menu.
LAN connection
The third connection method is very similar to the previous one, with the difference that they use twisted pair. The TV receiver is connected directly to the PC or through a router. This connection has a number of advantages:
- connection stability;
- high speed of information transfer;
- protection from external interference.
The only drawback is the need to run a cable from the router or computer to the TV.
How to connect a TV as a monitor?
The input signal from TV is taken from the video card. For connection, a cable with appropriate connectors is used. The television receiver can serve as the main or additional display. In the second case, either duplication of the image or extension of the desktop is possible. You can display a video player with a movie in this area, and use the main screen for work.
The display mode on two monitors is set through the settings in the operating system. In Windows 8, you can call up the menu through the combination Win keys+P.
If there is no image on the TV, then the screen resolution is most likely set incorrectly. Select the desired number of points for the device in the settings. If there is no sound, then through the settings panel, select desired device for audio.
Summing up a little
The article discusses three ways to connect a TV to a computer. It can be used as additional display or turn into a real multimedia center.
Buying new tv Pay attention to the connectors present. The VGA interface is a thing of the past. In 2015, it is planned to abandon it altogether. So if it is not on TV, then you should not worry too much about it. But the presence of several HDMIs is a big plus. Through them, you can connect to TV and other devices. It will be much easier to exchange files between different devices.
Create a complete multimedia center in your home. Use digital technologies at full power, and your stay at home will become an order of magnitude more comfortable.
Video
Do you still remember how we used to watch movies using a VHS or DVD player? Before enjoying watching a movie, sitting comfortably on the couch, it was necessary to perform a kind of ritual. We inserted a disc into a player or a cassette into a tape recorder and pressed a couple of buttons on the remote control. And before that, you should once spend a little time setting up the equipment. Everything was simple and convenient. With the advent of computers in our homes and unlimited internet It has become much more convenient and at the same time a little more difficult. We have access to so many films that the collection of discs that used to be a source of pride is now best case just nostalgia. At the same time, we had a chance to master the possibilities of new technology.
A modern TV has already become a computer in itself, but still connecting a regular PC or laptop to it opens up interesting possibilities.
No matter how good the monitor is, the TV will be better for viewing. First of all, due to bigger size screen, and often because of the higher image quality. After all, TVs are created taking into account the wishes of movie lovers. However, using the TV as a monitor, you can not only experience the bliss of watching movies. The big screen is also great for gaming, watching photos and YouTube videos, etc. You can even chat on social networks and Skype. And in general, the TV can be used as a monitor. Trust me, it's worth a try! In addition, connecting the TV to the computer does not need to turn off the monitor. You can use both displays in turn. For example, watch movies on a large panel, and surf the Web on a monitor.
We will tell you how to connect a TV to a computer. Connecting a computer and laptop to a TV is the same. Therefore, our advice is relevant in both cases. We will consider in detail how the computer is configured on Windows example 7. This version of the system is often installed on home computers.
The easiest way to connect is with an HDMI cable. In consumer audio and video equipment, this interface has firmly taken the place of the best, and now it has begun to be used in computer technology. On your TV, if it belongs to modern LCD or plasma models, there will surely be an appropriate input. If multiple versions HDMI standard. Now almost all AV equipment has already switched to HDMI 1.4 (1.4a or 1.4b), which fully satisfies our needs, including the transmission of Full HD 3D video.
PC IN - this is often called the VGA input (PC input), but this is already an obsolete option
Our choice is HDMI!
First check if your desktop or mobile computer. The HDMI port on a desktop PC should be looked for on the back panel of the system unit (more precisely, on the motherboard or video card), and on a laptop - on the right or left side of the case. Is there such a port? Good. You will need an HDMI cable. On the one hand, it connects to the computer, and on the other - to the TV. The advantage of HDMI cables is that their length varies from 1 to 20 meters. Choose a cable of the length you need - you should not overpay for "extra meters". The second advantage of HDMI cables is that they carry not only video but also audio. By connecting a computer to a TV via HDMI, you can use the built-in TV speakers. If there are no acoustics at hand, then this is a good compromise. Let the speakers on the TV be modest, but it’s better to be like that than to have no sound at all.
So, for clarity, let's divide the process of the first connection into steps:
1) First of all, unplug your computer and TV from the network. If your TV is connected to a cable from a collective antenna, disconnect it for now.
2) Connect the HDMI cable to the corresponding ports on the TV and computer. Connect both devices to the network.
3) Turn on your computer and wait for Windows to load.
4) Turn on the TV and select in its menu (using the remote control or buttons on the case) HDMI input to which you connected the cable. Modern TVs usually have several of these inputs. In the TV menu, they will be labeled something like this: HDMI 1, HDMI 2, etc.
Before plunging headlong into the world of cinema, you should also do Windows setup. So that the computer perceives the TV as a monitor. Let's divide the setup process into several steps:
1) Right-click on the "Desktop" Windows and in context menu Select "Screen Resolution". The Display Settings menu appears. You will see which monitor is connected to the computer, what resolution it has, and what image orientation is selected.
2) Click on the "Find" button that the computer has found the TV. In the "Screen" line, in addition to the monitor, a second item will appear (in our case, this is SONY TV - see screenshot). This is our TV. Yours will most likely have a different name. In the future, Windows will "remember" the second monitor and it will be displayed in this menu when you connect the TV. By default, "Orientation" will be landscape - you do not need to change this item. Check that the proposed resolution (in the paragraph of the same name) matches the resolution of your LCD or plasma panel. By the way, if in the TV settings there is an item to display a pixel-by-pixel image, activate it.
3) Here we are in for a surprise. Windows allows you not only to use a TV instead of a monitor, but also to use it together with a monitor. There are two use cases. First, you can "clone" the image on the displays. Moreover, even if they have different size, resolution and aspect ratio. Secondly, you can expand the "Desktop" to both screens. In this case, for example, the child can watch cartoons on the TV, and you can do your own business on the computer using the monitor. You can select the mode in the "Multiple screens" line.
4) When connecting a TV with an HDMI cable, you can use its built-in speakers. After all, the HDMI interface provides for the transmission of video and sound over a single cable. All you have to do is tell Windows that you want to use the TV for sound output. In Control Panel, select Sound. A menu of the same name will appear, in which you will see a list audio devices. It should have an item with the word HDMI in the title (we have AMD HDMI Output). Select this item and click on the "Default" button - the sound will go to the TV speakers. When you turn off the TV, then this the menu will disappear corresponding item... and will appear the next time you connect. And to activate a regular sound card, you need to perform a similar operation in the "Sound" menu (we have "Speakers").
What if the computer or laptop does not have an HDMI port? In that case, you should use alternative interfaces: DVI, DisplayPort or use a device such as . Your computer must have a DVI or VGA port, because a monitor is usually connected to it, but DisplayPort is still rare. In terms of quality, DVI or DisplayPort is best. TVs usually do not have such inputs, so you need to use an adapter or a special DVI to HDMI adapter or DisplayPort-HDMI. If your TV has such an input, use regular cable DVI-DVI or DisplayPort-DisplayPort. And the connection and setup process is the same as with HDMI. Except for the step about setting the sound.
Memo: what connectors do modern TVs have (HDMI 3, 4, 5 and 6 on the left in the top row)
If your PC does not have an HDMI, DVI, or DisplayPort port, you can use a VGA or other connection. analog interface(S-Video, etc.). True, this option will not be ideal in terms of signal transmission quality. That's why analog connection for modern TVs should be used when it is not possible to connect via one of the digital interfaces.
When connecting the TV to a PC to watch videos, no special settings are required. You watch movies the same way as before: you use the same player and watch the same files. When will you use big screen TV for games, then in their graphics settings, select the same screen resolution as your TV. In the vast majority of cases - HD (1366×768) or Full HD (1920×1080). Also, check your TV settings to see if it has special mode for games (Game mode). When selected, the TV is optimally configured to make games look spectacular, and responds most quickly to commands, which is important for dynamic games. By the way, some models with passive 3D technology have a game mode for two on the same screen with different images for each person (for example, LG 55LM960V and Philips 46PFL8007T).
AT recent times TVs have received many new features. So, it is already difficult to imagine modern TVs without the function of displaying 3D video and the Smart TV software shell. In addition, they have improved switching capabilities. New models of LCD panels and plasmas can be connected to a computer wirelessly - via Wi-Fi! More precisely TV connects to local wireless network and scoops content from the computer. The benefit of most TV latest generation There is a built-in Wi-Fi module. If you do not have a Wi-Fi network, you can connect the TV in the old, proven way - via Ethernet. In household appliances, the RJ-45 port (also referred to as LAN, Ethernet) was practically not used before, and now many TV models have it. The main thing is that the TV supports the DLNA (Digital Living Network Alliance) standard, which is no longer a rarity in our time. Incidentally, most Smart functions TV requires a connection to the Web, so one way or another it is worth taking care of it.
Wireless TV connection has become a reality. Sometimes it is not clear to which source it is connected.
Connecting mobile devices to the TV
Why is there a computer - now you can even connect a smartphone and tablet to the TV Android based and iOS. True, only new and often not budget models. For example, the VIERA remote App allows you to use your smartphone and tablet as a remote control and content source for Panasonic TVs. And Samsung has developed a proprietary system for sharing content between Allshare devices. Thanks to it, smartphones and Samsung tablets also transmit video to TVs of their own brand and serve as remote controls. Philips has such a "chip" called MyRemote. In any case, set special program on a smartphone or tablet.
No, it's not that big remote...it's a tablet
Of course, Apple could not ignore this interesting direction. Although the company does not yet have its own TVs, but it does have a content store and various devices that can play it. And thanks Apple media player TV allows you to stream content from your iPhone, iPad, iPod, and Mac to your TV screen (any brand). Apple TV connects to the TV with an HDMI cable, and receives a signal from gadgets via Wi-Fi (using a proprietary AirPlay technology). Since you can transfer not only videos, but also photos and music, the content that you have in iTunes will be available on the big screen. In addition, Apple TV allows you to use the popular online services YouTube, Vimeo and Flickr and bring the content you watch on your Mac offline. By the way, there are other media players that are designed to work with Windows and provide similar features. Moreover, they are compatible with services like Megogo and can even download content from the Web.
already developed and universal standard- MHL (Mobile high definition link). So far, the standard is in development, but some TVs and monitors already support it. In this case, using the appropriate cable, you can display the image from the gadget (which must also be compatible with MHL) on a large screen, almost the same as from a computer.
So, summing up, we predict that TVs will soon be able to display content from various devices: simply and without wires. In the meantime, the easiest and most affordable way for almost every way to connect a desktop PC and laptop to a TV is to connect them using HDMI cable. By the way, the method described by us is also suitable for connecting a second monitor or projector.
You can read about how to connect a TV to a computer below on this page.
Part 1: Before you start
To successfully connect the TV to the computer and display the image on the TV, first of all, you should make sure that both the TV and the computer have the necessary outputs and inputs for connecting the appropriate cables, as well as all the necessary adapters:
If you have a desktop computer ( desktop computer) , then you need to make sure that the video card has at least one of the following outputs on the back of the system unit and the TV must have at least one of the corresponding inputs:
 |
- designed to output an analog signal. You can connect a monitor to it cathode ray tube(CRT) or liquid crystal display (LCD), as well as a TV that has given input is present. |
 |
– analog video output for connecting a TV. The signal quality is higher than in the case of connecting via the VGA output. |
 |
Composite video output ("tulip" or RCA) is the traditional analog video output found on most TVs. |
 |
DVI output ;- intended for output digital signal. You can connect any modern LCD monitor and TV that has the appropriate input for connection to it. Sometimes it is necessary to use special adapters to ensure that the signal is output on another connector (see the description below "Required cables and adapters"). |
 |
version provides a picture resolution of 2560x1440 pixels with a billion (48 bit) color shades and progressive (full-frame, not interlaced) scanning. In addition to HDTV, all major TV formats are supported, including PAL, NTSC, ATSC, etc. Synchronization of video and audio by markers is provided: the movements of the lips of the actors. |
Combinations of these outputs on video cards for desktop computers along with connectors for connecting monitors can be different (see below):
 |
 |
In the event that there is a need to connect a TV to a computer with an existing monitor, and there are no S-Video, composite or DVI outputs on the video card, then you can replace the existing video card with a new or used one with such outputs. For high-quality viewing on a TV, we recommend having a video card with a video memory of at least 128 MB or more (the more video memory, the faster the video signal is processed). When a non-standard 7-pin output is found on video cards, it is better to keep that adapter , which the
is included with the video card, because there are several standards for wiring such a cable.
If the computer has integrated video card(this can be determined by the VGA output in the immediate vicinity of the keyboard and mouse connectors), then such a video card do not support connecting a second monitor (TV). Then if motherboard has a special connector for installing an "external" video card (today these are AGP or PCI Express), then you can install such a video card with some kind of output for connecting to a TV, while the integrated video card should be disabled in the BIOS.
If you have a laptop computer(laptop), then most often the connection to the TV is made either through the S-Video output
(available on almost all laptops), or via the VGA output (see below):
 S-Video laptop computer outlet |
 VGA output on a laptop computer |
Necessary cables and adapters (depending on the connection method):
 |
 |
 |
| SVideo cable | S-Video Connector (Zoom) | VGA cable |
 |
 |
 |
| DVI cable | adapter S-video - RCA (“tulip”) | DVI-I to VGA adapter |
You also need an adapter for audio streaming from a computer to a TV - in order to control the volume from the TV remote control, and not on the computer's speakers. Adapter data with Jack Stereo to RCA are connected to the output on the computer's sound card (where speakers or headphones are usually connected) and may look like this:
 |

| Examples of adapters from Jack Stereo to RCAA | |
Part 2. Connection and setup
Connection procedure and precautions Never connect the TV when the computer is on! Disconnect the plugs of both the TV and the computer from the power outlets, otherwise you can burn the inputs on both the TV and the video card!
Connection order:
- Turn off the TV, disconnect the plug from the socket.
- Unplug the antenna plug from the TV - as it is connected to collective antenna the TV can have a potential difference of more than 100 volts with an ungrounded computer, as well as all wires belonging to audio / video equipment (VCRs, DVD players, music centers And so on).
- Turn on the TV. The connection setting for different video cards looks different, the names of tabs, groups of controls and buttons may also look different - all this does not allow you to universal instruction for setting up absolutely all video cards,
but in each case, approximately the same procedures are followed. It should also be noted that the quality of the video signal will not deteriorate when the TV is connected to the computer.
For Windows XP computers In this example, a desktop computer with Windows XP installed was used to connect to the TV service pack 2, with GeForce graphics card FX 5600 via S-Video cable.
Connection order:
- Turn off the TV, unplug the power plug, unplug antenna cable.
- Turn off the computer, unplug the power plug.
- Connect the TV and computer with the necessary video and audio cables using the appropriate adapters
- Turn on the computer, wait for the operating system to load.
- Turn on the TV, select the INPUT S-Video function in the TV settings. 1) Right click on empty place Worker table, go to Display Properties, select the tab | Settings
Click on the monitor with the number 2, right-click and select Enable:
If the Extend my Windows desktop onto this monitor mode is selected, then it becomes possible to move the window with the player to the TV screen with the mouse. A double click on the image or a key combination will expand the player to the entire TV screen. Double-clicking on the image again or pressing the keys again will return the image to windowed mode. After finishing watching the program, you need to return the player window from the TV screen to the monitor.
At the bottom of the settings window, click the button Advanced(Additionally). In the window that appears, select the section Default Monitor and NVIDIA GeForce FX 5600 Properties, and in the section nViewdisplay settings choose the mode clone as below:
After pressing the button apply you may need to restart your computer.
AT following example To connect to the TV, we used a laptop computer with the Windows XP Service Pack 2 operating system installed, with an ATI RADEON 7500 video card via an S-Video cable. The connection procedure and basic settings are practically the same as those considered for NVIDIA graphics cards(see below):
Mode Extend my Windows desktop onto this monitor set as desired. In the most simple case advanced settings you can not do it on the Advanced button. For computers with an operating system Windows Vista In this example, a laptop computer was used to connect to the TV. Dell Inspiron I1520 with installed Windows Vista Home Premium via S-Video cable.
Connection order:
- Turn off the TV, pull out the plug from the socket, pull out the antenna cable.
- Turn off the computer, unplug the power plug.
- Connect the TV and computer with the necessary video and audio cables using the appropriate adapters
(in this example, via S-Video cable). - Turn on the computer, wait for the operating system to load.
- Turn on the TV, in the TV settings, select the function INPUT S-Video.After turning on the computer, the resolution may immediately change (for example, 720 * 480), and a screen like this should appear:
You need to set the mode Duplicate my desktop on all displays (mirrored) , then click OK. Then right-click on an empty spot on the desktop, select Personalize -> Display Settings
Next - you need to right-click on the monitor under the number 2 and select the item in the menu that appears. Attached. Then click on the Advanced Settings button and select the tab Intel® Graphics Media Accelerator Driver for Mobile (see below):
Next, click on the button Graphics Properties, along the way to confirm the change of settings in the window that appears user account control choose Continue and in the window that appears, select the mode Intel® Dual Display Clone and for Secondary Device select the mode Television(or Monitor ):
after clicking on OK, you need to return to the window with display settings, click on the monitor with the number 2. There are 2 viewing modes on the TV:
- the image is displayed both on the monitor and on the TV at the same time - in this case, you must uncheck the item ;
- the image from the monitor is “dragged” by the mouse outside it onto the TV (as on the 2nd screen), making it possible to work on the computer with other applications and at the same time watch programs on the TV - in this case, you must check the box Extend the desktop onto this monitor - see below:
If the operating mode is selected Extend the desktop onto this monitor, then it becomes possible to move the window with the player to the TV screen with the mouse. Double clicking on the image or a key combination will expand the player to the entire TV screen. Double clicking on the image again or pressing the keys again will return the image to windowed mode. After finishing watching the program, you need to return the player window from the TV screen to the monitor.
In some cases, after the changes made, a restart of the computer is required.
1) There is a program TV Tool(you can download it from the site http://tvtool.info/), which does not require any video card settings. It is quite easy to manage - when you start this program, you can simply click - and a picture with video card will go via one of the video outputs and the corresponding cable to the TV. TV Tool works with any video cards based on nVidia chips, except for the GeForce4 MX. Video cards with chipsets from other manufacturers (ATI, SiS, Trident, etc) are not supported by TV Tool. Supported operating systems Windows 98, Me, Windows 2000, XP, Vista. After installing the TV Tool, you need to make some settings - select the signal type, resolution and picture size, as shown below:
Setting TV format depends on your region television standard(format) – see table:
Now, every time before displaying an image from a computer to a TV, the procedure will be as follows: - launch the TV Tool; - go to www.vidachok.tv and select a program to watch; - open the program on Full Screen on the monitor; - press on the keyboard - the picture should disappear on the monitor, and appear on the TV. 2) Sometimes, after connecting the computer to the TV, the image becomes rather cloudy, with noise, synchronization can also “break down”. This may happen for the following reasons:
- Cable resistance is below 75 ohm (cable resistance is written right on it);
- Possible unstable work power supplies on the computer or on the TV. When connecting additional equipment this leads to the operation of such unstable power supplies at the limit of their capabilities, which affects the quality of the picture;
- When you connect a grounded computer to the TV, you get two ground points (one at the far end of the TV
- cable, the other - in the computer), as a result of which image noise is possible. You can get rid of this by disconnecting the antenna cable from the TV for the duration of the operation.
- poor quality cable and bad connection cable.
When buying a TV with flat screen it is best to take a laptop with you to the store, cables for connection with adapters and try to connect it to the selected TV in the store. Thus, you can immediately find out if it is possible to connect such a TV to a computer at all, and also see the quality of the output signal to the TV.
Today, modern LCDs and LED TVs almost completely replaced television receivers with a cathode ray tube, but simply a kinescope. Modern televisions are distinguished by high picture and sound quality, but apart from this, LCD and LED televisions are great for use as a monitor.
Advantages and disadvantages of connecting a TV to a PC
- Their matrix allows you to comfortably work with any applications, watch movies from the Internet on a wide screen and play, view photos and content social networks, as it does not create flicker and does not harm eyesight.
- In addition, when acquiring an LCD TV as a computer monitor, it is quite profitable from an economic point of view. You can watch both TV channels and work on a PC without buying a separate monitor for it.
- A TV receiver connected to a PC can be used as a signal source for recording on-air broadcasts on a computer hard drive.
But that's the advantage of using modern TV end as a monitor, let's move on to the disadvantages, the main of which is different size pixels: on the TV they are more, and on the monitor, respectively, less. That is why the image quality from a PC will not be as saturated as it could be on a monitor. Besides:
- If the TV resolution is less than 1920 x 1080, the clarity of the image is significantly degraded and the angular fonts can be seen.
- Many budget LCD TVs have low matrix response. Any sufficiently dynamic content on such a device will not look very correct.
- For web surfing, a large-screen TV is also not a good choice. For normal view, you will have to work behind such a device from a long distance.
However, many are interested in how to connect a computer to a TV and use it instead of a monitor for playing games and watching movies.
Video adapter requirements
The video card must be equipped with two connectors - this is the most important requirement for it. As a rule, most video adapters have 2 VGA connectors or a combination of VGA and DVI connectors, but more modern ones have a pair of high-speed HDMI digital interfaces. However, depending on the manufacturer and model of the video card, the combination of connectors may be different.
Let's take a closer look at the connection external screen instead of a monitor VGA cable, since all video cards and more than 90% of television receivers are equipped with this interface.
VGA connection and setup process
Connecting a computer to a TV begins with the purchase of the necessary VGA-VGA cable in any store computer components. As for the length of the cable, it is better to take 1.5 distances from the required. In case of rearrangements of furniture, repairs, etc. you do not need to disconnect the PC from the TV and do not buy a new cable.
As a rule, connecting a TV to a computer via a VGA interface is not difficult even inexperienced user. If everything is in order with the equipment and cable, the TV as a monitor should work immediately.
Only the image is transmitted over the VGA cable. To connect audio, use an audio cable by connecting it to the output sound card and a television receiver.
HDMI connection and setup process
This is the most suitable option, since according to digital interface HDMI not only transmits video, but also audio, so no additional audio cable is needed.
Sound problems
Despite the fact that according to HDMI interface not only video is transmitted, but also sound, it often happens that the sound comes from the PC speakers, but is not transmitted to the TV. The most common reason is settings.
After this procedure, the sound will come from television receiver, not from the PC speakers. In this simple way, you can always connect your PC to your TV. Good luck with your purchases and enjoy your viewing.
