Is the full-screen feature in YouTube not working for you? There are a few different kinds of glitches that you can encounter. These issues can range from a piece of your browser or desktop showing while in full-screen mode to full-screen functionality being disabled. Most of the time, restarting your browser or computer will fix the problem; if not, there are some settings you can tweak to prevent the full-screen error from occurring. This wikiHow article teaches you how to address and fix YouTube full-screen issues encountered in Google Chrome on Windows, Chromebooks, and Mac computers.

Quickly Fix the YouTube Fullscreen Glitch

The first thing you can try is pressing "F11" (Windows + Chromebooks) or "Cmd + Shift + F" (Mac) when you have a Chrome web browser open. Sometimes extensions or browser themes cause the issue, so check and disable any if needed.

  1. Sometimes a YouTube page will load incorrectly, causing graphical issues. If this is the reason you're encountering a full-screen error, pressing the F5 key or clicking the "Refresh" button will reload the YouTube page and fix the problem.
  2. If your Chrome window takes up the whole screen, it may show a small amount of the desktop when using YouTube in full-screen mode. You can solve this by clicking the box-shaped button in the upper-right corner of the window (Windows) or the green button in the top-left corner (Mac) and then trying to use YouTube in full-screen mode.

  3. If part of your desktop is showing while YouTube is in full-screen mode, press F11 (Windows) or Command + Shift + F (Mac) to place Google Chrome in full-screen mode. This may expand the YouTube window to fill the screen.
  4. In some cases, the full-screen error is caused by Google Chrome failing to load correctly; to solve this, close Chrome, then re-open it and go back to the video you were watching.
  5. If the last three options didn't work for you, turning off your computer and then turning it back on will usually fix YouTube's full-screen issues in Google Chrome.
    • This should solve the full-screen problem in most cases. If you try restarting your computer and find that the full-screen issue persists, try the following methods.

  2. If you began noticing full-screen issues immediately after installing an extension, chances are that the extension is to blame. Disabling (not removing) the extension may solve the problem.
    • Chrome updates can also cause some older extensions to become unstable, resulting in unusual errors.
  3. It's in the top-right corner of the window. A drop-down menu will appear.
  4. This is in the drop-down menu. Selecting it prompts a pop-out menu.
  5. It's at the top of the pop-out menu. Doing so opens the Extensions page.
  6. The switch will turn white, signifying that the extension has been disabled.
    • Repeat this step for any other necessary extensions before proceeding.
  7. Once you've disabled any potentially problematic extensions (or all of your browser's extensions), go back to your video and click the "full-screen" icon in the bottom-right corner of the player. If an extension was causing the problem, the player should now be on full screen with no problems.

  • Question
    What do I do if YouTube doesn't go full screen and only zooms in on the Video?
    Community Answer
    Close the tab and open it again. If that doesn't work, press F11 to make Chrome itself fullscreen. Once you've watched the video, press F11 again to exit the fullscreen mode.
