IN Windows Vista no support full screen mode user interface DOS COM applications. One of the main signs is the inability to open full screen window for shell command line in Windows Vista.When you try to open or run DOS COM applications,package or game scripts that rely on command line, including cmd.exe itself, you will encounter the following error message:

This system does not support full screen mode. Select Close to close the application.

Lack of support full screen DOS command line V Windows Vista is quite annoying, especially for those who still play games for DOS and for Windows 3.1/9x, use outdated software such as WPDOS or programmers who often switch to command line to use DOS based programming language such as Pascal.

There is a solution to this problem for support full screen window in Windows Vista. In almost all possible ways to solve a problem, you are guaranteed to be able to work in your Vista with dos applications, which will be broken down in some way, at least into parts in Windows Aero. You will lose the nice Aero Glass interface when trying any of these tricks, as well as other unknown side effects.

Solution to launch window in full screen mode

Method 1: Use XDDM instead of WDDM video drivers

In other words, install video card drivers from Windows XP for use in Windows Vista. If the video card supports hardware graphics acceleration in Windows XP,then you can download drivers for Windows XP for your video card and install them under Vista. However, please be aware that using XP drivers for the video adapter may crash your system Vista, so save your work before moving on and using drivers from Windows XP.

Note: This solution was recommended by Microsoft KB926657.

To install Windows XP video drivers under Vista, follow the procedures listed in the guide below. The steps should work for both NVIDIA and ATI video with graphics accelerators.

1. Download installation drivers for Windows XP for video card from NVIDIA or ATI.
2. Run the installer. Confirm any requests - allow User Account Control and warnings when prompted.
3. The installer will first extract and unzip the files needed for installation to navigate to a folder in the directory. Make a note of the folder path. For ATI, the folder for the installation files is usually located in a directory with a name that resembles C:\ATI\SUPPORT\7-5_xp_dd_46743\Driver or C:\ATI\SUPPORT\7-5_xp_dd_ccc_wdm_46743\Driver, with the only difference being the version number and driver build numbers.

Likewise, NVIDA's driver packs will also unpack themselves into a folder, typically named according to the structure C:\NVIDIA\Win2KXP\94.24 or something like that.

1. You must click Next as shown in the image above for the extracted installation files to take effect. Don't worry about clicking on the "Next" button, as the installer will throw a critical error message to stop somewhere in the process because the installer has detected that you are using a non-Windows XP operating system. The installer and associated drivers are designed to run only on Windows XP. The installation will be terminated.
2. Cancel driver installation when a request error message appears. In fact, as soon as you click on the OK button, you will automatically exit the installation.

1. Using Windows Explorer, navigate to the directory that contains the unzipped installer files.
2. Right-click the Setup.exe file, and then select Right-Click Properties from the context menu.

1. Select the Compatibility Mode tab. Check the box next to "Run this program in compatibility mode" and select Windows XP Service Pack 2 from the drop-down menu. Click OK when done.

1. Double click on Setup.exe to launch the installer and install the XP drivers in Vista.
2. Reboot the system and your Vista system is now able to open or run programs and command prompt in full screen mode.

Method 2: Using the standard video graphics driver VGA Graphics Adapter

Similar method to 1, but uses the built-in standard VGA graphics driver in Vista, which provides greater stability and compatibility with Vista, but much less functionality and feature support. The following steps are on how to install Standard VGA Graphics Adapter in Vista.

1. Right-click on your desktop and select Personalize from the pop-up context menu.
2. In the personalization dialog, click the Display settings link.
3. On the Monitor tab of the display settings window, click the Advanced options... button.
4. If you are not already on the Adapter tab, click on the Adapter tab to activate it. Then click on the Properties button in the Adapter Type section. Allow the UAC request.

1. On the Adapter Properties display, go to the Driver tab.
2. Click on the Update Driver… button. Then select the "Browse this computer for driver software" option.

1. Click on the option “Let me choose from a list of drivers already installed on my computer.”

1. Select from the list and highlight Standard VGA Graphics Adapter when prompted to select the device driver you want to install for this device, then click Next.

1. Windows Vista will install a new standard VGA video driver to replace the original driver for your graphics accelerator. If your monitor goes blank (no signal), wait five minutes, then turn off your computer and restart as usual. If your monitor does not turn off, wait until the drivers are installed.
2. Click the Close or OK button on all dialog boxes repeatedly until you return to the desktop or the computer is restarted.
3. Restart your computer if you were not prompted to do so or did not do so.

Once the computer restarts, you should be able to open programs or a command prompt shell in full screen mode. You may have to set the resolution again, as well as everything related to display settings.

If you want to change this procedure and reinstall your display card's manufacturer, follow the same instructions again, but select the option to have Windows automatically install the appropriate software for your system instead of viewing your drivers on that computer. If you are unable to do this, click on the Properties button on the Adapter tab, go to Device Manager and directly select Update driver software from the right-click context menu.

Method 3 - Using DOSBox

It is an Intel x86 and DOS emulator application for Windows. The open DOSBox application customizes the shell window, which emulates the DOS environment for sound, graphics, mouse, modem, etc., and also allows DOS applications and games to run. DOSBox handles all requests between the Windows OS and the DOS window, allocating memory, controlling processor speed, and allowing you to make settings for sound card emulation, graphics type, key mapping, mouse sensitivity, resolution, full screen mode, etc.

Althougn DOSBox cannot add features to Windows for DOS programs that run on DOS systems and some DOS features that do not have them in native mode, but its utility is still great, allowing almost all currently available 32-bit versions of Microsoft Windows - NT4, XP, 2000, 2003, Vista and 2008 to run legacy applications and games.

Some tweaks and tweaks must be done in order to get DOSBox working to be able to play your games or run old applications. Basic Setup and Installation of DosBox is a guide to using DOSBox. Since DOSBox emulates DOS, you will have to deal with a lot of command line syntax in the command shell. If you are not familiar with the command line, there are several graphical interfaces for DOSBox that present all the settings in a typical Windows interface, and allow users to connect different profiles with different configurations optimal for different games, DOS or programs. Please note that when using DOSBox, it is best to disable User Account Control to get the best performance and so that DOSBox can properly simulate sounds, VGA colors and CPU speed. In the days of DOS, there was simply no such thing as user account-based and user-level functional restrictions, so any restriction could cause problems with the emulated application.

Another problem is sticky Windows keys, accessibility features for physically disabled users. Sticky Keys is activated by pressing a specific sequence or combination of keys that the average user rarely or is unlikely to use, such as pressing the Shift key continuously 5 times. But these keystroke sequences may be needed during DOS games. What's worse is that DOSBox doesn't handle this correctly, and it's not the main OS keyboard or mouse activity section. So you better need to disable sticky keys permanently, so that they cannot suddenly appear and disrupt the game.

Again, using DosBox and or its GUI may also cause some applications or games to exhibit abnormal game behavior, such as the system randomly crashing or the game not starting at all.

Today we will be interested in full-screen mode in Internet browsers. What it is? How to activate and disable it? We will have to understand all these issues further. In fact, even a novice user will be able to cope with the task. Although, as practice shows, the “full window” mode in browsers is not used very often.

Description

What is full screen mode? Not every modern user knows about this function.

The "full window" option allows you to hide all elements of the program/browser and displays the main field of the utility. In our case, the active site will be displayed on the entire monitor. This is very convenient, for example, when reading books and manuals in electronic form.

Activation via settings

How to enable full screen mode? This is not difficult to do. Especially if you know how to behave correctly. The first scenario is to use the Internet browser settings. Instructions for activating full screen mode will look like this:

1. Open browser.
2. Click on the button responsible for opening the functional menu. It is usually located in the upper right corner. This is a button with three dots or horizontal lines.
3. Click on the frame image. This button is usually located near the "Scale" line.

It is done. After the completed manipulations, the user will open the Internet browser in “full window” mode. The technique does not require any special skills or knowledge.

At the Opera

Full screen mode in the Opera browser is activated differently. But in general, the algorithm of actions will not require anything special.

The instructions for launching the option being studied are as follows:

1. Launch Opera.
2. Right-click anywhere in the browser.
3. Select the line that says "Full Screen".

That's all. Full screen mode will be activated. To exit it, just press the Esc button on your keyboard.

Keyboard to help

How can I make full-screen mode different? There is another option for the development of events. It is used much more often in real life, especially by advanced computer users. We are talking about using "hot keys". They help users activate different commands in programs. And browsers are no exception.

To make a page in an Internet browser full screen, you will have to:

1. Launch the browser. You must wait until the application is fully loaded.
2. Go to the page you want to display on the entire PC display.
3. Press the F11 button.

After these steps, the user activates the “full window” mode in the browser. To exit it, you can click on Esc or press F11 again.

Important: the presented algorithm of actions is suitable for most browsers. It definitely works in Yandex, Chrome and Mozilla.

On a Mac

We figured out how to make full screen mode in the browser. But these are not all the tips that will help you achieve the desired result. They are suitable for Windows owners. Today, some people use Apple branded products. This company offers iOS and MacOS operating systems. You need to be able to work with them. And not everyone knows how to do this.

Full screen mode on MacOS is enabled in the browser in almost the same way as on Windows. The MacBook keyboard will help bring your idea to life. To make the Internet browser on MacOS full screen, you need:

1. Go to the browser and open the desired page.
2. Press and hold the Shift, Command and F buttons on your keyboard at the same time.
3. Release the listed keys.

The matter is completed. Full screen mode will be launched. To exit it, you will have to repeat the previously described algorithm of actions. This technique works for most modern Internet browsers. Otherwise, the user will be helped by previously proposed solutions to the problem.

One of the common problems that inexperienced Internet users have: when they try to expand the video to full screen (full screen mode) in any browser, the image disappears and only sounds remain. Most often this concerns the sites youtube and vkontakte... Sometimes the entire browser as a whole can also slow down, and when exiting full-screen mode, the flash player plugin may completely freeze and not display flash elements at all. Also, the settings of the flesh plugin may differ in different browsers, and therefore, for example, in Opera everything can work fine, while in Mozilla Firefox 4 this glitch is detected.

Causes of the problem

As can already be seen from the introduction, as often happens, again, most likely, the flash player is to blame for your problems! Sometimes this is the crookedness of the plugin itself, sometimes it is the complex relationship between it and your computer’s hardware (in particular its drivers).

In order not to torment you with various guesses, I will briefly list simple solutions that can quickly help in this situation.

Solution

Follow each successive step until the problem disappears:

1. Click the second mouse button on the window with the playing video in normal mode, click the parameters button (or settings) and in the window that opens, in the leftmost tab, uncheck the box. This will disable hardware acceleration.
2. In the same window, make sure that the local storage size (third tab from the left) is not less than 100kb. But it’s also better not to set the mode without restrictions...
3. This item can also help if any flash objects on sites heavily load the processor, if they are not displayed at all or even lead to the browser crashing. Go to your browser's plugin manager and first, make sure that Adobe Flash Player is there and that it is enabled. Then check that the flash plugin is only listed once in your plugin list and not multiple times. If you have flash plugins of other versions enabled at the same time, remove them all, leaving only one of them - the latest version. The same, by the way, applies to all other plugins and extensions of different versions (for example, some java extension can do this), so check everything at once. These types of errors lead to unnecessary useless processor loads or the appearance of incomprehensible errors and freezes during operation.
4. Reinstall your video card driver.
5. If all of the above does not help: remove the Flash plugin, restart the browser and install the latest version back. Go through the first two points again.

Watching a video in a small window is not convenient, and it is not always possible to expand it. From this article you will learn what to do if the video does not expand to full screen on YouTube in player programs.

Full screen mode on YouTube

To enable full-screen mode in YouTube on your computer, click on the icon in the lower right corner of the player. To exit full screen mode, press Esc.

To open a YouTube video in full screen on a tablet or smartphone, click on the video and then on the arrow icon that appears (Android), or the full-screen mode icon (iOS).

If you are watching a video via YouTube, the player has a button to activate theater mode in the lower right corner, which will stretch the video.

If the video does not open full screen

The Full Screen button may be visible but not active (greyed out).

Browser ban

Check if the mode is enabled in your browser.
For Firefox:

1. In the address bar, type about:permissions and press Enter.
2. Select the All Sites tab.
3. Change the "Full Screen Mode" option to always ask.

In Chrome and browsers based on it, to manage exceptions for full screen mode, you need to enter chrome://settings-frame/contentExceptions#fullscreen in the address bar. For each domain, you can create a rule to allow or prohibit the use of full-screen video.

Conflicting extensions and plugins

Make sure that the installed plugins and extensions do not prohibit viewing full-screen video. Change settings or disable add-ons.

Other reasons

Viewing the video in full screen could be prohibited by the owner of the site on which the player is embedded.

For example, on Twitter YouTube cannot be opened in full screen. To get around this restriction, you need to go to the video page on YouTube itself. To do this, click on the logo or title of the video in the player.

Also try opening the video in another modern browser. Your browser may not support this feature.

Old or incorrectly saved videos (in the wrong aspect ratio) may have black margins. They can appear left and right, above and below, or from all sides at once.

Full screen video in players

In players for Windows, the video initially does not open in full screen. Using hotkeys you can open it in full screen mode. Usually this is a double click, LAlt+Enter or Enter.

If you've opened a video full screen but there are wide black bars around the edges, change the aspect ratio. For example, in VLC player you need to right-click on the video and select “Video - Aspect Ratio”. The most common options that help are 16:9, 16:10, and 4:3 (depending on your monitor).

The same ratio will need to be selected in the “Video - Crop” item.

If you are able to view Flash videos but you are unable to view them if you try to make them full screen, then you may have a problem with the Flash player and your video drivers. This article describes how to work around this problem.

• If you are unable to view Flash content at all, see Flash Plugin - Keep it up to date and troubleshoot problems .
• If you are unable to view videos at all, see Fix common audio and video issues.

Preload the libGL.so.1 library

On Linux, this problem can often be resolved changing the command used to launch Firefox so that a graphics library is loaded along with Firefox:

Reset Zoom

Press and hold command Ctrl while pressing 0 to reset the Firefox zoom.

Disable Flash hardware acceleration

Note: When Flash videos are in full screen, the use of hardware acceleration depends on a Flash setting and not the Firefox hardware acceleration setting.

First make sure you are using the latest version of Flash (to check your version visit this Adobe test page) and then do the following:

If this workaround allows you to view full screen videos, you should try to update your graphics drivers.

If the problem is not solved, go to the next section.

Many people like to watch different videos on YouTube on various topics. Housewives, for example, search for and watch videos about cooking or useful life hacks; fishing enthusiasts watch useful videos about interesting places where you can catch a lot of fish. Everyone watches YouTube, from young to old. When watching a video, you want to expand it - open it in a more convenient mode - full screen, but sometimes you can’t open the video in full screen. The YouTube video does not open in full screen.

Absolutely anyone who wants to watch this or that video can encounter this situation. Therefore, in this article you will learn what to do when a YouTube video does not unfold completely.

Full screen mode on YouTube

If you want to expand a video on YouTube, that is, open full screen mode, then you need to click on the “expand” icon in the lower right corner of the video player. If nothing changes when you click the expand button, then you need to understand the problem and why this is happening before you fix it.

Why doesn't full screen mode open on YouTube?

Most often, this problem may occur due to problems with your flash player. You may have an old version of this plugin installed, or it may be that your flash player is not working properly due to incompatibility with your computer software. There may also be a problem with your browser.

There can be a lot of reasons why YouTube fails and therefore the YouTube video does not open in full screen.
In order not to torment ourselves with guesses as to why this happened, let's solve this problem.

What to do if the video does not open?

1. Check to see if you should disable full screen mode in your browser. To do this, enter about:permissions in the address bar and press Enter. Next, click on the tab that you will see in front of you - all sites and in the desired option below - full screen mode, you need to select - always show. If everything in your browser was as written, then the problem is not in it.

2. It is quite possible that the flash-player plugin itself is buggy. Uninstall it and reinstall it again. After this there should be no problems. An outdated version of the plugin may have been installed.

3. Go to the list of installed programs and plugins on your computer. It is very possible that you have several versions of the flash-player plugin installed, and this may lead to the plugin not working correctly and you may have problems opening full screen mode.

4. If your computer has a Windows operating system, then you need to know that the video there does not open on its own in full screen. This can be corrected by pressing the key combination - Alt+Enter. And the video will expand to full screen.

It seems to be a very simple problem that anyone can encounter and not immediately understand what is what and why suddenly the video does not open in full screen mode, and the reasons can be both simple and technical. But thanks to our advice, you can cope with this situation without any problems.
