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

Why is full screen not working on Google Chrome?

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

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.

Solution 1 – Enable Flash

Since the Adobe Flash Player is now implemented in Chrome, you won’t be able to tweak settings like before.Your first step should be to check for possible Flash Player conflict that’s the best-known culprit for this and similar issues.

On older versions of Chrome, users were able to access ‘plugins’ settings trough address bar. However, with the latest few versions, it’s required to use built-in settings to tweak your Flash Player.

  1. Click on the 3-dot icon and open Settings.

  2. Open the Settings tab on the left side.
  3. Click on Show Advanced Settings.
    Google Chrome full screen fill not full
  4. Under Privacy, open Content settings.

  5. Scroll down until you reach Flash.
  6. Click on Ask first before allowing sites to run Flash.

  7. Exit and restart Chrome.
  8. Try out any video.

Solution 2 – Disable Hardware Acceleration

An additional built-in feature that may provoke playback is the Hardware Acceleration. Hardware Acceleration is there to relieve the CPU of rendering multimedia graphics (videos, pictures, etc.) and use the GPU instead.

However, some users with integrated GPU’s reported various issues related to this feature.

So, you should at least try disabling it and check for results. If the problem persists, don’t forget to enable Hardware Acceleration again.

  1. Open the Settings tab.
  2. Click on Show Advanced Settings.
  3. Under System, uncheck the Hardware Acceleration box.

  4. Restart Chrome and check for changes with the Full screen feature.

Disabling hardware acceleration might cause high CPU usage. We got your back with the best software you can get.


Solution 3 – Reset Chrome settings

In some occasions, your best bet is to reset your settings. This solution applies not only to Chrome for Windows 10, but Android version as well.

Besides standard settings reset, we advise you to take a look individually on installed extensions as some of them are known for the interfering with the built-in flash player (Ad blocking extensions, especially).

In case you accidentally delete a good extension, first check our fresh guide to backup Chrome extensions.

If that didn’t help you, move on to settings reset.

  1. Open the Settings tab.
  2. Select Show Advanced Settings.
  3. Scroll to the bottom of the page and click Reset Settings.

  4. After the procedure is finished, restart your browser.

With this workaround, many users succeeded to resolve the issues with full screen.


Solution 4 – Update/Reinstall Chrome

For the last resort, you may either check for updates or reinstall Chrome from scratch. And when we say ‘reinstall’ we mean completely wipe all remainings. So, you should back up your bookmarks and saved passwords.

Don’t worry, it’s never been easier to save your passwords with these manager programs. As for bookmarks, you can easily save them with these nifty tools.

To update Chrome, follow these instructions:

  1. Click on the 3-dot icon and open Settings.
  2. Click Help>About on the left side.
    Google Chrome full screen not working
  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.

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 IOBit Uninstaller (free download), so be sure to try it out.

Once you remove Chrome using this application, install it again and check if the issue is still there.


Solution 5 – Change Display scaling settings

According to users, sometimes your scaling settings can cause full screen issues in Google Chrome.

However, you can fix that problem simply by disabling a single setting. To do that, you just need to do the following:

  1. Right-click Chrome shortcut and choose Properties from the menu.
    Google Chrome full screen glitch
  2. Go to Compatibility tab and check Disable display scaling on high DPI settings.
    Google Chrome full screen fill not full
  3. After doing that, click Apply and OK to save changes.

After doing that, try to start Google Chrome again and check if the issue is still there.

Solution 6 – Switch back to the default theme

Google Chrome supports all sorts of customization, and you can even change the look of the entire theme. However, you should know that changing your theme can sometimes lead to certain issues.

Speaking of which, many users reported that changing the theme caused issues with full screen to occur.

If you’re having full screen issues, it’s advised to switch back to the default theme in Chrome. This is quite simple and you can do it by following these steps:

  1. Click the Menu button in the top right corner and choose Settings from the menu.
  2. Now scroll down to the Appearance section and click Reset to default button.

After switching back to the default theme, the Google Chrome Full Screen mode not working issue should be resolved completely. Many users reported that this solution worked for them, therefore we strongly suggest that you try it out.


Solution 7 – Make sure that Chrome isn’t maximized

This is just a workaround, but it works according to users. If the Chrome doesn’t fill the screen in full screen mode, you just need to ensure that the application isn’t maximized.

Simply resize the Chrome window before going to the full screen and the issue won’t appear anymore.

This is a strange bug, however, this workaround might be helpful until you find a permanent solution.


Solution 8 – Consider using Beta or Canary version

If you’re having issues with the full screen mode in Chrome, it might be a good time to consider trying out Beta or Canary version. The Beta version offers new features and upcoming bug fixes, and if you’re eager to fix this problem, we suggest to try out the Beta version.

If the Beta version also has this problem, your next step would be the Canary version. This version is less stable, but it offers bleeding-edge updates and bug fixes, so you might want to use it until the issue is resolved.


Solution 9 – Duplicate the open tab

According to users, if you have issues with full screen in Chrome, you might be able to fix the problem simply by duplicating the tab that you want to view in full screen.

This is incredibly simple, and you can do it by following these steps:

  1. Navigate to the desired website in Chrome.
  2. Before you go to full screen, right-click the tab you want to view in full screen and choose Duplicate from the menu.

  3. Once the new tab opens, switch to it and enter full screen mode.

As you can see, this is quite a simple workaround, but until you find a permanent solution you might have to use this method.


Solution 10 – Consider switching to a different browser

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

Editor's recommendation
ur browser
  • Fast page loading
  • VPN-level privacy
  • Enhanced security
  • Built-in virus scanner

Windows 10 has Microsoft Edge as the default browser, but if you’re looking for something more powerful, Firefox is always a good alternative. Also, you can try UR browser for enhanced privacy protection.

That should resolve your issues with Google Chrome Full Screen mode not working. Don’t forget to post your questions or suggestions in the comments section.
