I am using Windows 11 and sometimes experience problems when watching videos in a web browser. The video may buffer, stop playing, or show a blank screen even though my internet connection is working.

What Windows settings, browser settings, or graphics-driver checks should I try to troubleshoot video playback?

I would like to know the recommended troubleshooting steps before reinstalling the browser or changing any advanced system settings.

    1

    Open Edge.

    Click the 3 dots at the top right and select Settings.

    Go to System and Performance - System.

    Disable the Graphics Acceleration setting.

    Restart Edge and test if that resolves the problem.2

    If that does not resolve the problem, download the Edge installer from this link, then use that to reinstall Edge on top of the existing installation.

    Try these checks in order before reinstalling the browser or changing advanced system settings:

    1. Confirm the video format and decoder path in Edge
      • Open edge://media-internals in a new tab.
      • Reproduce the playback problem.
      • Check the player properties for the codec, such as codec: h264 or codec: avc1.
      • Check kVideoDecoderName:
        • D3D11VideoDecoder or MediaFoundationVideoDecoder = hardware decoding
        • FFmpegVideoDecoder = software decoding
      • If the same file also fails in the built-in Windows player, the issue is more likely format support than a browser setting.
    2. Verify hardware acceleration in Microsoft Edge
      • Go to edge://settings/system.
      • Make sure Use graphics acceleration when available is turned on.
      • Restart Edge.
      • Open edge://gpu and confirm Video Decode shows Hardware accelerated.
      • Then test playback again and recheck edge://media-internals to see which decoder path is being used.
    3. If hardware acceleration is enabled but playback still fails
      • Update the GPU driver from the device manufacturer.
      • Toggle Use graphics acceleration when available off and back on, then restart Edge.
      • Recheck edge://media-internals to see whether the decoder path changed.
    4. Check for unsupported or narrowly supported formats
      • Edge does not support every codec natively.
      • H.264, VP8/VP9, and AV1 are supported.
      • HEVC is conditionally supported and requires a valid HEVC Video Extension and working decoder path.
      • XAVC / XAVC HS is not supported by the built-in Windows playback stack.
      • If a file uses an unsupported or narrowly supported format, convert it to H.264 video with AAC audio in an MP4 container and test again.
    5. If the issue is HEVC-specific
      • Open edge://gpu and check for: Failed to create HEVC decoder instance, License check for app failed (0xC00DB3B3).
      • In edge://media-internals, check whether HEVC decoder initialization failed.
      • If needed, check the installed HEVC package in an elevated PowerShell window: 
             Get-AppxPackage -AllUsers *HEVC* | Select-Object Name, PackageFullName
      • If the HEVC extension was installed from a third-party platform, reinstall the official Microsoft Store version. Removing and reprovisioning app packages changes installed components, so use that step carefully.
    6. Check Windows audio output if playback problems seem tied to sound devices
      • Select the Speakers icon on the taskbar.
      • Select the arrow next to the volume slider to open the list of audio devices.
      • Verify audio is playing to the intended output device.
      • If audio problems are also present, run the Windows audio troubleshooter in Get Help.
    7. Use Windows Update for baseline system fixes
      • Go to Start > Settings > Windows Update.
      • Select Check for updates.
      • Install available updates and restart if prompted.

    These steps cover the common causes called out for browser video playback on Windows 11: disabled hardware acceleration, codec or extension issues, and graphics-driver problems.
