Question

The video is lagging and freezing on the second monitor.

Alex Smith 20

Good afternoon.

I have two monitors connected in mirroring mode. One monitor is connected via DVI (LG E2241), and the second monitor (Samsung TV) is connected via HDMI. The system is Windows 11 (I had the same issues with Windows 10, but everything worked fine with Windows 7). The processor is AMD 3200G. When playing video in any player on the second monitor, I experience micro-freezing and stuttering. It's as if frames are being dropped. I've tried all the system settings, driver settings, adrenaline software, and TV settings. Nothing helps. The video stutters and freezes in all players on the second monitor. It's especially bad if I pause and then start the video. Both monitors are set to 60Hz and the same resolution. The drivers are up-to-date. I'm out of ideas on how to fix this. Has anyone else encountered something similar?

Hi Alex Smith,

Thanks for reaching out to the Microsoft Q&A Forum. I understand that the video on your second monitor is lagging and freezing. Please try making the TV behave like a PC monitor. On the Samsung TV, set the HDMI input label to PC (or rename the source to “PC”) and turn Game Mode = On, Motion/Micro‑judder/Smoothing = Off, Film Mode = Off, Noise Reduction = Off. If available, disable Instant On/Quick Start features. These steps reduce extra processing and enforce RGB 4:4:4 timing.

Also, match the exact refresh timing. In Settings > System > Display > Advanced display, confirm each display’s refresh rate. If one shows 59 Hz and the other 60 Hz, that’s 59.94 vs 60.000. In AMD Adrenalin > Display > Custom Resolutions, add a 60.000 Hz timing for the TV (CVT‑RB) or switch both to 59 Hz (59.94) so they share the same rate. If you can, temporarily switch from Duplicate to Extend (just to test). If the stutter disappears, the issue is timing coupling in mirror mode.

If the issue persists, try turning off Multiplane Overlay (MPO) on Windows. MPO can cause freeze/stutter with some players on multi‑display setups. Disable it to test:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm]
"OverlayTestMode"=dword:00000005

Save as DisableMPO.reg, double‑click to import, reboot, and test. To revert, delete OverlayTestMode or set it to 0.

Thank you for your detailed response.

After making the registry changes, I didn't notice any significant improvements in video quality. BUT. My system scaling was set to 160%. I reset the monitor duplication mode to the recommended 150%. The video quality seemed to improve significantly. I don't know if this helped, but the video stuttering was significantly reduced.

Hi,

Thanks for your response. Glad to hear that your video quality improved significantly. As changing scale helpful, try to force consistent color format from the GPU. In AMD Adrenalin > Display > Pixel Format, choose RGB 4:4:4 Full for the HDMI output.

In general, I've noticed this pattern: the larger the system size, the more video playback lags in players. It's the system size that affects video quality, not the monitor resolution, but the system size. Additionally1:

The problem is likely with the "Multiplane Overlay (MPO)" feature. Disabling it improves video quality. I disabled it like this:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm] "OverlayTestMode"=dword:00000005

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers «DWORD (32)-DisableMPO=1

Additionally2:

The video still lags, especially noticeably if you pause and then press play. There's no smoothness. One video might play smoothly, but as soon as the second episode starts, it starts lagging. :-(

Hi,

Thanks for your response. Try using AMD Cleanup Utility > reinstall latest chipset + Adrenalin drivers. Also, can I ask your second monitor using as Duplicate or Extend?

I removed everything using AMD Cleanup Utility. Then I installed the drivers through the update center. This didn't solve the problem. Any other options? Monitors in duplicate mode.

Hi,

Thanks for your response. Please test with Extend Mode. If stutter disappears in Extend, the root cause is Duplicate timing coupling. Many systems cannot fully stabilize Duplicate with mixed EDID timings.

Hi,

Could there be a driver issue? My second monitor (Samsung UE40F6130 TV) is detected in Device Manager as "Generic Monitor (SAMSUNG)" and has driver 10.0.26100.7019 installed, development date June 21, 2006 (from Microsoft). Are there any newer drivers available?

p.s. I'm currently testing the extended mode.

Hi,

Thanks for your response. You're seeing “Generic Monitor (SAMSUNG)” with a driver dated 2006 because Windows uses a class driver for most displays. TVs generally don’t ship a Windows-specific “monitor driver”. Instead, they expose capabilities via EDID (the display’s self‑description) and Windows maps that to the built‑in Generic PnP/Monitor driver. That 2006 date is a long‑standing placeholder for Microsoft’s in‑box monitor class driver and doesn’t indicate the real freshness of your GPU or display stack.

For the newer “monitor drivers” available, typically no, especially for TVs. Manufacturers rarely publish a Windows monitor INF for TVs; EDID is sufficient. Using Generic PnP/Monitor is expected and supported.

Since you’re testing Extended mode now, if Extended mode is smooth (common) and Duplicate still shows micro‑freezes, it’s a timing/duplication constraint rather than a “monitor driver” problem. Many systems are rock‑solid in Extend because each display keeps its own EDID timing. Duplicate forces one timing across both and can surface tiny mismatches. Use Extend for everyday viewing and switch to Duplicate only for presenting. Thank you.
