Google Chrome is the most-used browser in the world with more than 50% of the market share. It’s present on all devices you could imagine and excels in a lot of features.

However, Chrome is not perfect. One of the most reported issues is related to playback and video streaming.

Namely, it seems that the Google Chrome Full Screen mode is not working for some Windows 10 users.

This especially goes for YouTube videos. Additionally, it may open windows that are not filling the entirety of the screen.

For that purpose, we prepared a few workarounds that should help you resolve these and similar issues.

What can I do if full screen isn’t working on Google Chrome?

  1. Consider switching to a different browser
  2. Update/Reinstall Chrome
  3. Enable Flash
  4. Disable Hardware Acceleration
  5. Reset the Chrome settings
  6. Change Display scaling settings
  7. Switch back to the default theme
  8. Make sure that Chrome isn’t maximized
  9. Consider using Beta or Canary version
  10. Duplicate the open tab

Google Chrome is one of the best browsers on the market, however, it has its share of issues, and many users reported that full screen mode doesn’t actually fill the screen.

Speaking of Chrome issues, here are some similar problems that users reported:

  • Google Chrome full screen fill not full – Many users reported that full screen doesn’t fill the screen in Google Chrome. This can be a major problem for some users, but you can fix the issue by switching to the default theme in Chrome.
  • Google Chrome full screen not working – If full screen mode isn’t working in Chrome, the issue might be your scaling settings. Simply adjust them and check if that solves the problem.
  • Google Chrome full screen glitch – If you’re experiencing glitches in full screen mode, that might be because your browser is out of date. To fix it, install the latest version or switch to the Beta/Canary version and check if that solves the problem.

1. Consider switching to a different browser

If you can’t fix the problem with the full-screen mode and Chrome in Windows 10, you might want to consider switching to a different browser.

We recommend Opera for a lot of reasons but the most important one is speed. This browser’s Speed Dial, Ad Blocker, Instant Search, and other features will have you browse the web faster than ever.

Unlike other browsers, Opera has a lot of built-in features so you don’t have to look for extensions or add-ons.

One of the most important features found in this software is the integrated VPN service that helps protecting your privacy online. It’s free and can be used for an unlimited time.

If you don’t believe us, just download it and try it for free.



Opera is less prone to errors, it's speedier and consumes fewer resources than other browsers. Bonus: free VPN!

  3. This will start an automatic check for updates and download them accordingly.

If you have the syncing feature enabled, your browsing history and bookmarks will be stored in the cloud, so there’s no need to backup anything manually.

Other important information

Bear in mind that Chrome can leave certain leftover files, so you’ll need to find and remove them manually. You can find these files in the following directories:

  • C:\Users\<YourUserName>\AppData\Local\Google Chrome
  • C:\Program Files\Google Chrome

On the other hand, if you want to be sure that all leftover files and registry entries are removed, you might want to use uninstaller software to remove Chrome.

There are many great uninstaller applications on the market, but one of the best is Revo Uninstaller, so be sure to try it out.
