How to Fix YouTube Full Screen Not Working on Desktop?

You can try various solutions to resolve the issue. One of the easiest solutions to try would be to refresh the webpage and restart the browser. Using YouTube in the Incognito mode is another probable solution. 

Some other fixes with a detailed description are presented below to help you resolve the issue. 

Refresh the Webpage

If the YouTube videos are not playing in full-screen mode on your computer, one of the first things to try is to refresh the webpage. You can simply press the F5 button on the keyboard or click the refresh icon near the address bar. After that, try again switching the video to the full-screen mode. 

For Mac users, you need to hover the cursor to the address bar, and the refresh icon will be visible. Click on it. Or, you can press the Command + R keys on the keyboard.

Restart the Browser

You can press the Command and Q keys together to close down the browser on Mac.

Likely, Mac users need to press Command in place of Ctrl along with other keys.

To do so, 

  1. First, open the YouTube site on the browser.
  2. Then, click the Profile photo on the upper-right end of the screen.

  4. The browser will scan for any accessible updates. If the system detects an update, it will take some time to complete the update.
