      Hello everyone,

      I am encountering an issue with YouTube not playing in full-screen mode, and I am seeking insights and potential solutions from the community. It can be frustrating when attempting to enjoy videos in full-screen mode, only to encounter difficulties or limitations that prevent the desired viewing experience.

      Despite my efforts to enter full-screen mode on YouTube, I have noticed that the videos do not expand to fill the entire screen. This situation prompts me to explore the potential causes that may contribute to this issue.

      Why is YouTube not playing in full screen mode? If any of you have experienced a similar problem or possess knowledge about the factors that can prevent YouTube from playing in full-screen mode, I would greatly appreciate your assistance. It would be immensely helpful to understand any known considerations, such as browser or device compatibility issues, conflicting extensions or plugins, or other technical aspects that could affect the functionality of full-screen mode on YouTube.

      Hello Alexandra! It can indeed be frustrating when YouTube doesn’t play in full-screen mode as expected. There could be several factors contributing to this issue. Let’s explore some potential causes and solutions:

      Browser Compatibility:

      • Ensure that you are using an up-to-date version of a compatible browser. Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari are commonly supported browsers for YouTube.
      • Try accessing YouTube in full-screen mode using a different browser to see if the issue persists. This can help determine if the problem is specific to your current browser.

      Browser Extensions or Plugins:

      • Some browser extensions or plugins may interfere with YouTube’s full-screen functionality.
      • Temporarily disable any extensions or plugins related to video playback, ad-blockers, or custom CSS stylesheets to see if they are causing the issue.
      • Clearing your browser cache and cookies can also help resolve potential conflicts.

      Hardware Acceleration:

      • Hardware acceleration is a feature that offloads certain tasks to your device’s hardware, improving performance. However, it can sometimes cause issues with full-screen playback.
      • Try disabling hardware acceleration in your browser’s settings:
      • In Google Chrome: Go to Settings > Advanced > System > Use hardware acceleration when available.
      • In Mozilla Firefox: Go to Options > General > Performance > Uncheck “Use recommended performance settings” > Uncheck “Use hardware acceleration when available.”

      Video Player Controls:

      • Occasionally, the YouTube player controls or settings may affect the full-screen experience.
      • When in full-screen mode, move your mouse cursor to the bottom of the video player to ensure that the controls are visible. If the controls are not showing, try moving the cursor to make them appear.
      • Additionally, check that the “Theater mode” or “Cinema mode” options are not enabled accidentally, as they can prevent full-screen playback.

      Operating System and Device Considerations:

      • Ensure that your operating system and device meet the minimum requirements for playing YouTube videos in full-screen mode.
      • Keep your operating system and device drivers up to date to ensure optimal performance.

      YouTube Playback Settings:

      It’s worth checking your YouTube playback settings to ensure there are no restrictions that prevent full-screen mode. To do this:

      • Click on your profile picture in the top-right corner of the YouTube homepage.
      • Select “Settings” from the dropdown menu.
      • Go to “Playback and performance.”
      • Ensure that “Allow fullscreen” is enabled.
      If none of the above solutions resolve the issue, it’s worth trying to replicate the problem on a different device or network to determine if it’s specific to your setup. If the issue persists, you can reach out to YouTube support for further assistance.

      I hope these suggestions help you resolve the issue with YouTube not playing in full-screen mode. Good luck, Alexandra!
