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 depending on different browsers, and therefore, for example, everything can work fine in Opera, while in Mozilla Firefox 4 this glitch is detected.
Causes of the problem
As you can already see 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.
Solving the problem
Follow each successive step until the problem disappears:- 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 turn off hardware acceleration.
- 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...
- 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 most later 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.
- Reinstall your video card driver.
- 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.

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”. Most often, choosing between 16:9, 16:10 and 4:3 ratios (depending on your monitor) helps.
The same ratio will need to be selected in the “Video - Crop” item.

YouTube player supports four modes - default, wide screen, mini-window and full screen. The most enjoyable way to watch videos is in full screen, but when they try to switch to it, for some users absolutely nothing happens or the message “Cannot switch to full screen mode” appears. The problem occurs infrequently and is usually resolved by completely reinstalling the browser, however, you must agree, reinstallation is still a last resort. Why not try less radical methods first.
YouTube full-screen mode may not work for a variety of reasons, including errors in browser updates, cache and files, function failures, and so on. In any case, you need to start looking for the source of the problem with the simplest thing - restarting the browser. If the cause was a failure that caused temporary changes in the browser configuration, then restarting will restore normal operation of full-screen mode, but if it does not help, try restarting the computer.
API settings in Chrome and Firefox
Problems with full-screen mode in Chrome can be caused by disabling the “Secure Content” section settings. Go to the internal address in your browser chrome://settings/content/protectedContent and make sure both settings are enabled.
In Chrome, you should also try to maximize the player window after minimizing the browser window itself. It is not known what the catch is, but judging by the feedback from forums where problems with full-screen mode were discussed, this little trick has proven its effectiveness more than once.
If you use Mozilla Firefox, check the parameter status full-screen-api.enabled V hidden settings browser. Visit the flags page about:config, use the search string to find the specified parameter and make sure it is true.
It's also a good idea to disable hardware acceleration and see how that affects full-screen mode. In Chrome, acceleration is disabled in additional settings(the “System” block), in Firefox – in the settings of the “Performance” section after unchecking the “Use recommended settings...” item.
Disabling extensions
It is possible that the cause of the problem was one of the malfunctioning extensions, especially those related to the player settings. Disable the extension and see if it does anything or not.
Private mode
Check if you can expand the player window to full screen in incognito mode. If so, the problem is most likely in the cache or cookies. Clear all history data and see if that helps restore full screen mode. You can clear cache and cookies in Chrome on the settings page chrome://settings/clearBrowserData, in Firefox for this you need to go to the address about:preferences#privacy.
Deleting a profile
If all the methods described above do not work, try logging out of your user account, if you are using one. Let's look at this procedure using Chrome as an example. Click on your avatar, select “Synchronization” in the menu and disable it on the settings page that opens. Then, in the same menu, select the “Manage users” option, and then, using the button in the form of a vertical ellipsis, delete the current user in the window that opens.
This action will clear the profile folder, completely deleting cookies, bookmarks, cache contents and other user-related data. As a last resort, you can completely reinstall the browser by cleaning up the “tails” in the directory %userprofile%/AppData/Local. Such a radical step will certainly allow you to restore the normal operation of the full-screen mode of the YouTube player.
