Connecting a TV to a projector. We connect an additional monitor, TV or projector to the computer

Instruction

Now select the connector through which you will connect to the projector. Modern ones have VGA and HDMI channels. Less common is DVI video input. Purchase desired cable and connect the desired devices with it. Turn on the TV and select the main signal reception channel.

Adjust the settings for the computer, projector, and TV to work in sync. Open the screen settings menu. Click the "Find" button and wait for the second device to be detected. Select the equipment (computer or projector) whose screen will be the main one. Activate the corresponding function.

Specify the setting for the monitor to work in sync with the projector. Considering the fact that a TV is connected to the last device, it is better to use the Extend Screen function. Activate it and click the "Save Changes" button. Now an identical image will be displayed on the TV screen and the projector canvas, different from what is transmitted to the computer monitor.

If you are an avid movie buff or just enjoy watching movies at home in good quality then you need to buy a video projector. In this article, you will learn how to choose a projector for your home on your own.

The principle of operation of the projector is that the light from the lamp forms an image, passing through certain elements. Depending on what these elements are, projectors are divided into LCD (liquid crystal) and DLP (micromirror). Both types have their advantages and disadvantages. The advantages of LCD are its gentle effect on vision and compactness. Of the shortcomings, not enough to mention saturated color. The main advantage of DLP projectors is more high quality, and the disadvantage is that the eyes get very tired when viewing for a long time.

note

Some TVs have a USB connector but do not play some multimedia formats. In such cases, you can not do without the "omnivorous" media player.

A tuner is a special device that decodes the incoming signal into a format understandable by the TV. Currently, satellite receivers, which are included in satellite TV kits, are widely used. To view it, you need to correct setting channels.

Instruction

Connect the tuner to your TV using the included cable and available connector. Choose the most convenient channel for default use satellite receiver. AT manual mode set the "Search for a channel" command. It is important that the tuner is turned on and the numbers are displayed on its screen. Save the channel, then you can watch it satellite channels by switching them on the receiver itself.

Add to tuner new channel by scanning the desired transmitter on the selected satellite. Determine first which channel you want to tune. You can use the instructions that came with your receiver or the table at http://www.tv-sputnik.com/ch_select.php. With its help, you will determine where this or that channel is located, and familiarize yourself with its settings in the list of transponders.

Open the section of the tuner menu responsible for transponder settings. The name of the section may differ depending on the device model. Install the desired transmitter. Click on the remote remote control transponder autoscan button and add channels on the receiver. This operation should be carried out several times a month, since the list of satellite channels may change.

• Brightness. Models with a brightness of less than 1000 lumens can only be used in darkened rooms. Projectors 2000-3000 are also suitable for conference rooms and auditoriums, they create a clear image even in daylight. 3000-12000 lumens image projectors are considered professional and are used in concert halls, clubs and cinemas.
• Technology. Models in which the image is formed using LCD - the best combination of price and quality. The best image projectors are equipped with DLP technology for twice the contrast. There are also models on LcoS, they are considered more reliable, as they give a homogeneous image.
• Dimensions. Along with portable devices weighing 2-3 kg, there are portable devices weighing 3-5 kg ​​and stationary devices weighing more than 10 kg, they require special installation.
• Purpose. To display images and presentations, the projector must have a sensor optimized for various permissions. To create home theater, you need a model with a matrix that supports the appropriate video formats: 480p, 570p, 720p, 1080i, 1080p, etc.

Top Models image projectors

Projector Large Venue gives a very clear and quality image, combines all modern technologies- this is perfect option for displaying presentations or images in large rooms. It uses SmartFormat to project a widescreen image instantly, and automatically disconnects from the network when a presentation or video ends.

Epson projector The EH-TW6600 lets you create your own home theater with 3D video. Ability to convert 2D to 3D, scaling in a ratio of 1.6, Full resolution HD, 2500 lumens brightness - all this makes it one of the best in its class.

Another 3D projector from Epson EH-TW5200 with 2000 lumens color brightness and 1080p video resolution is more affordable. At the same time, it also makes it possible to view 3D video, however, without conversion.

Modern projector models provide for projecting images from computers and TVs onto special surfaces to increase the resulting image. Most often, this technical tool is used to show presentations in large rooms. Many users are faced with the problem when they need to connect the projector to a TV and not to a PC.

In order to connect the projector to a TV, you will need:

• video cable;
• projector.

First you need to make sure that both devices (on the projector and TV) have video signal connectors. These can be transmission channels such as RCA, HDMI, VGA, etc. If the TV and the projector do not have the same connectors, purchase a special adapter.

Connect the unit to the TV using the appropriate cable. The quality of the picture will depend primarily on the data format. So, highest quality signal transmission is provided in the HDMI format.

HDMI cable

Most often, modern TVs use VGA and HDMI channels for data transmission. Older models support the RCA channel (tulip).

Next, you need to make video transmission setting. open system menu your TV and select as the connection type the appropriate data transfer format with which you synchronized work technical means. If necessary, define the synchronous operation parameter. For a TV, it is preferable to use the "Expand Screen" option.

Wireless connection to TV

Modern models provide wireless synchronization with multimedia equipment. For these purposes, new devices come with special HDMI-devices, which are responsible for the transfer of multimedia information from one device to another.

1. Turn on the equipment and make sure you have a pair of dedicated HDMI transmitters. Without them, it is impossible to carry out wireless synchronization.
2. Insert the HDMI transmitters into the appropriate sockets on the equipment case.
3. Connect the transmitters to the USB connector of the TV or other device from which they can be powered.
4. Set the transmission parameters according to the instruction manual.

Advantages and Disadvantages of Wireless Sync

This method has its own set of advantages and disadvantages. The disadvantages include:

• high price for wireless equipment;
• small delay in signal transmission.

The high price is, perhaps, the only significant disadvantage of this type of equipment. In addition, the repair process, due to the more complex technical device, will also cost a lot.

Signal delay in 0.1 sec. almost imperceptible and is not a criterion by which it is worth making your choice.

Among obvious benefits this method connections can be distinguished:

• lack of wires;
• the ability to connect with any type of device;
• the quality of the transmitted picture.

Ease of use is a definite plus this method. long distance transmission distance (about 10m) allows you to place the receiver and transmitter in different rooms. The ability to connect any device with an HDMI connector makes it equally easy to connect to a computer and laptop, as well as to TV.

Modern projectors are used to display images on special surfaces. Usually this method used to increase the size of the image, which is very useful when showing presentations in large rooms.

Instruction

In a bar equipped with an inexpensive Epson projector (I think that it costs 10-15 thousand), with a screen diagonal of about 2 meters - until there were spectators, it was possible to safely test the projector. The experience of watching video on a screen of 2 meters is superior to all these plasmas and LCDs combined! You watch a movie, not a TV, and after you also watched a projector at your friends’ houses, you realized that this is what you need to watch a movie on bigger screen, especially since the price tag for them is now very humane, and the screen size is limited only by the room.
Those. for the price of an ordinary LCD TV with cartoonish color reproduction, you can get such a screen size (at least 300 inches !!!), which is simply unrealistic for an LCD, or real, but for unrealistic money.
Do not rush to run to the storehouse for a projector - there are small subtleties in this matter, it is better to know them yourself, and not listen to the salespeople in the store.

I purchased an HD projector EPSON EH-TW3200, which cost the price of an ordinary TV.
On the first day, I was connected to a Pioneer DV-575A DVD player with a short RGB cable, which ended up in the household.
The picture was projected onto a light-beige water-based emulsion wall about 2 meters away - they watched the whole evening.
From the quality of the picture they went nuts right away - wow factor on the face. I tried to hang the available screen (1.2 meters) - I didn’t find a difference in the quality of the picture, only the color rendition changed a little (you can adjust it in the projector through the menu for correction) - it’s not critical at all.
So the fable about the fact that the projector necessarily needs an expensive screen has not been confirmed by me. A flat white wall painted with a water-based roller is quite enough.

Switching source - video projector

Modern projectors have on board all the necessary inputs. Projector EPSON EH-TW3200 equipped with two HDMI inputs, VGA, Component (RGB), S-Video and Composite inputs.
Then I realized that I can only send an RGB (component) signal from an old Pioneer DV-575A - the next day I bought a piece of a 9m component cable and 6 RCA connectors, gave about 1500 rubles, soldered it myself.

RGB(abbreviation English words Red, Green, Blue - red, green, blue) - additive color model, which describes the method of color synthesis for color reproduction.
Component video cable- provides three-dimensional color space used to encode an analog color video signal and transmit it over three channels.

An HDMI cable would cost ~500 rubles, but there is no socket on the source. Because the EPSON EH-TW3200 projector supports FULL HD, it would be more logical to take an HDMI cable, and add the money saved to the purchase of an HD source that will no longer have RGB outputs...

High Definition Multimedia Interface(HDMI) is a high-definition multimedia interface that allows the transmission of digital video data. high resolution and multi-channel digital audio signals.
HDMI connector provides a digital DVI connection to multiple devices and is a modern replacement for analog standards connections such as SCART or RCA.

With the cable, we managed to drag the projector to the place of deployment, where it was supposed to be mounted - the picture was 3 meters wide with the maximum wide angle of the lens and the minimum was about 1.5 meters.
Those. you cannot get an image size of 3 meters wide from a distance of 1 meter, just as you cannot get a picture of 1 meter from a distance of 4 meters. These parameters for projectors differ (I think that it is insignificant), in order to estimate the capabilities of the projector to obtain the required size, you need to look Projection Calculator, with which you can determine the size of the image that the projector can produce for a certain distance.
Projection Calculator exist for each projector model.

Selecting a Projector Location - Geometry Adjustment

Manual on EPSON EH-TW3200 draws a diagram - strictly perpendicular to the screen. Strictly perpendicular - the window, so I shifted the optical axis by 0.7 meters to the side - the image became a crooked quadrangle ....
Two ribbed wheels next to the lens allow you to move the lens left and right and up and down so that the image shifts a maximum of 96% of the height of the projection area up and down vertically and 47% of the width to the right and left horizontally from the center position .
By turning the projector and turning the adjustment wheels, it is possible to set a 100% correct rectangle.

Adjusting the brightness of the video projector and dimming the room

Brightness control EPSON EH-TW3200 has 4 positions:
- Dynamic (the brightest);
- Living room;
- Neutral;
- Movie.
Preset No. 2 "Neutral" turned out to be the most optimal for watching the video (conditionally 50% brightness). Fan power is adjusted automatically when a brightness preset is selected.
Fan noise EPSON EH-TW3200 does not strain at all, although the projector is directly above your head, because. The noise is heard only during pauses.

You can watch during the day, but it is somewhat uncomfortable, i.e. Knowing what kind of picture is obtained in the dark, you definitely want to darken the room.
Similarly: you can drink warm beer, but it doesn't taste good...
Thick curtains help, but do not give 100% darkness, because. do not stick to the wall.

I hung roller-blinds made of 100% light-transmitting material on the windows - at the edges of the window the material bristles, loosely adhering to the wall and transmits light.
I attached a U-shaped profile to the wall - a plastic box for a cable 30x35 (40 rubles per 2 meters), inside which I launched a roll-curtain. Looks very aesthetic.

Significantly expand their functionality, including broadcasting the image from TVs or computers to increase the size of the video. But a reasonable question arises, is it possible to watch TV through a projector, what must be taken into account for this?

Can I watch TV through a projector? What does it take to create a real cinema?

Modern devices are adapted to stable work with a wide range of equipment, and TVs are no exception.

Is it possible to watch TV through a projector - check the functionality of our device

Before connecting, make sure that specific device transmit video signal. If you are working with a projector that is not capable of reading information from media, then you must, first of all, connect it to a computer.

Now the following scheme of work should turn out: computer -> video projector -> TV. We select the appropriate video card connector through which the connection to the computer will occur. The best option- work with digital channel such as HDMI or DVI-D.

Of course, the corresponding port for connecting the cable must also be in the video projector - we recommend that you make sure of this in advance. If there is no such port in a particular video projector, you can use the VGA channel. To do this, there are many VGA adapters on sale - they can be found at a symbolic price to easily connect a computer.

How to connect a projector to a TV - a simple procedure

After that, the next question arises, how to connect the projector to the TV.

Next, we have to choose a connector for the connection. The functionality of modern TV devices involves support for HDMI and VGA channels. Less common is the DVI video input option. Taking into account the channels supported by your TV, we purchase a suitable cable and connect it. It remains only to turn on the TV and indicate the main signal reception channel.

Configure the settings for synchronous operation of all devices. In the screen settings menu of your TV, click "Find". Wait a little and see available list available devices to connect. Here we select a computer monitor or video projector, which will be the main one. After activating this feature, you can install additional settings for a better reflection of the picture - here everything is already individual for each model.

In most cases it is enough to connect necessary devices using a suitable cable - and in the settings that appear, select desired device as a source for displaying the image. This approach is universally applicable to everyone. trademarks presented within the last ten years.
