Second screen started lagging since update from windows 10 to 11.

Hi there,

Since support for Windows 10 ends in October 2025, I finally decided to upgrade from windows 10 to 11.

Since doing so, my second screen (LG smart TV) has some stuttering during video playback.

I've used VLC and the internal Windows player to play different video files, and they all have moments of stuttering. It's like the fps drops a couple of frames. Audio keeps playing correctly.

When I move one of the players back to my main PC screen, the problem is immediately solved.

So basically I know the video files are not the problem, neither is the TV screen (it worked perfectly on windows 10 and also when I use the Netflix app for example).

When checking the screen settings everything is set to recommended, and the frame rates are set to 60Hz for the secondary screen (according to specs). Lowering this to 59,94Hz does not solve the problem.

I'm a 100% sure its something in Windows 11, and I've found multiple forum discussing with the same issue, without finding a clear answer that to any use of me.

Specs:

i9-9900k

RTX2080

16GB RAM

Windows 11 24H2 Windows Feature Experience Pack 1000.26100.48.0 (Build: 26100.3194)

All drivers, including GPU driver are up to date.

Hope you can help me out!

    Hi Martin,

    Thank you for your response.

    After writing this ticket, I kept trying to find a solution, and I found one that worked for me.

    However, before doing so, I did try reinstalling the GPU drivers and adjusting the display settings.

    For anyone reading this ticket and having the same problem:

    The solution for me was to set the refresh rate to 50Hz. The screen can handle 60Hz, but windows 11 (for some reason) can't.

    60Hz worked fine on Windows 10, but not on 11. It is worth the try to use different referesh rates to see if it solves the issue.

    Leaving this reply for other to see to see if Martin's options are helpful, or otherwise mine.

    Thank you for your support!

    Dear TerrorTed,

    Thank you for reaching out about the issue with stuttering during video playback on your second screen after upgrading to Windows 11. It’s frustrating when a seamless experience on Windows 10 has become problematic following an upgrade.

    Let’s go through some detailed troubleshooting suggestions to help resolve the issue.

    Reinstall Graphics Drivers

    Download DDU from a trusted source (such as their official website).

    Boot into Safe Mode by pressing Shift + Restart and selecting Troubleshoot > Advanced options > Startup Settings > Restart.

    Once in Safe Mode, run DDU to remove the current graphics driver completely.

    Afterward, reinstall the latest graphics driver from the official Nvidia website.

    For more information on how to use DDU, you can refer to the guidance notes provided by Intel's official website, which is based on an example of an Intel graphics card, and is equally applicable to NVIDIA and AMD graphics cards.

    How to Use the Display Driver Uninstaller (DDU)

    Disclaimer: Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites, or any support related to technology.

    Adjust Display Settings

    Right-click on the desktop and select Display settings.

    Scroll down to Multiple displays and ensure the correct display mode is selected (e.g., Extend, Duplicate).

    In Display settings, click on the Advanced display under Related settings.

    Ensure both screens are set to the appropriate refresh rate. Try setting both displays, if possible, to the same refresh rate to avoid sync issues.

    Change Video Playback Settings

    Open Settings by pressing Win + I.

    Navigate to System > Display.

    Scroll down to Graphics.

    Select Graphics performance preference and browse for the VLC Media Player or other media players you are using.

    Set their performance to High performance.

    Disable Full-Screen Optimizations

    For each media player (VLC, Windows Media Player), right-click on the executable (e.g., vlc.exe).

    Select Properties, then go to the Compatibility tab.

    Check Disable full-screen optimizations.

    Click Apply and OK.

    Change Connection Method: If you are using HDMI, try switching to a different HDMI port both on the TV and the graphics card. Alternatively, try using a DisplayPort or another available connection type to see if the issue persists.

    If the issue persists, please do not hesitate to reach out again or seek further assistance from NVIDIA or your pc manufacturer’s support teams.

    Best Regards,

    Martin | Microsoft Community Support Specialist
