What Causes YouTube Fullscreen Issues on Chrome?

Let’s first talk about why the full-screen problem happens before we fix it. The issue is that Chrome and Adobe Flash don’t work well together. Many YouTube videos use Flash. 

As Chrome is updated, sometimes the changes result in shockwaves flash, causing videos to not display correctly in full screen. The good news is there are settings in both Chrome and Flash that can efficiently resolve this.

Why Fixing Full-Screen Issues is Important

When trying to see all the details on that tiny screen, you might squint or struggle to make everything out. Or you may get distracted by the video borders and be unable to immerse yourself in the content thoroughly.

Low resolution in a small window also prevents the video playback from being crisp and smooth. Even worse, critical text, gameplay, or action can get cropped out from the missing edges.

Following the steps in this guide on “How to fix YouTube fullscreen on Chrome,” you can finally watch videos maximized properly across your entire display.

Prerequisites Before Getting Started

Before you try any solutions to fix YouTube’s full-screen issues, it’s essential to complete these preparatory steps first. Update your Chrome browser to the latest available version since using outdated Chrome can often worsen full-screen problems. Also, check if you have Adobe Flash installed and update it to the newest version.

Lastly, temporarily turn off any Chrome extensions you have added. Sometimes extensions end up interfering with videos going properly full screen. Temporarily turning off extensions can assist in pinpointing if they are the source of the full-screen malfunction.

Step 1 – Adjust Chrome Settings

The first place to look is Chrome’s settings, which control how videos display:

  • Open Chrome settings and uncheck the “Use hardware acceleration when available” box. Hardware acceleration can sometimes cause performance issues with YouTube.
  • Reduce animation speeds for scrolling, panning, and zooming to “No animations” or “Instantly” for a performance boost.
  • Restart Chrome after making the above changes for them to take effect fully.

Step 2 – Configure Adobe Flash Settings

Adobe Flash has various options you can tweak. 

  • To access them, right-click a YouTube clip. From the menu, choose “Settings.” That will open the Flash configuration panel. Update those settings for smoother full-screen videos.
  • Just like with Chrome, uncheck hardware acceleration in the Flash settings to prevent full-screen bugs.
  • In the Camera and Mic tab, make sure Flash is allowed access to those devices if needed.
  • Select “Always allow” on the General tab to let Flash run on YouTube without restrictions.

Step 3 – Adjust YouTube Player Settings

YouTube also provides its player configurations:

  • While signed into your YouTube account, access the video playback settings.
  • Uncheck options like annotations, cards, and end screens, which can sometimes interfere with the full screen.
  • If you have a fast computer, enable accelerated playback for smoother, high-quality video.
  • Check for any HD, 4K, or VP9 encoding options and enable them if available.

Step 4 – Disable Browser Extensions

Chrome extensions like ad blockers can sometimes impair full-screen functionality:

  • Disable all extensions and then test if the full screen works properly without them.
  • If the full-screen works, re-enable extensions one by one until you encounter the problematic one.
  • For essential extensions, check their settings to see if related options can be toggled off.

Step 5 – Try Alternative Solutions

If you still can’t get videos to full screen properly, there are a few other things to try:

  • Use keyboard shortcuts like F for the full screen instead of clicking the mouse icon.
  • Adjust the default zoom level in Chrome settings to lower or higher.
  • Test full screen on a different browser like Firefox to pinpoint an isolated Chrome issue.
  • Use YouTube’s Cinema Mode, which makes videos nearly full-screen with minimal borders.
