Drivers & Software

[sangnguyen207]

Hi all,

I'm using AMD Ryzen 7 7840HS with Radeon 780M Graphics. It just happen a few days ago to me and I dont know why, but now when I open a video file in computer or watch Netflix sometimes the screen froze, or the file play with only sound, sometime screen blackout a few secs.

I tried update drivers to 24.2.1 / roll back to 23.12.1 and nothing work.

I tried Disable RadeonT 780M in Device Manager, then I can open video file normally but can not connect to 2nd monitor.

Please help.

Regards.

Most likely you encounter the Multiplane Overlay MPO error
Have you tried turning off the "Multiplane Overlay" (MPO) in windows registry?
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm]
"OverlayTestMode"=dword:00000005

I have the same issue and setting this mode in registry didn't help unfortunately

Did you ever get any further in fixing this?

I have the same issue.

Netflix stops decoding video after 30s or so. If I disable the 780M and just leave the 7700S enabled, it plays fine.

It sounds like your Radeon 780M GPU might be having driver issues. Since updating and rolling back drivers didn't help, try these steps:

• Clean Driver Installation: Use DDU (Display Driver Uninstaller) to completely remove the current driver, then reinstall the latest AMD driver.
• Check for Windows Updates: Ensure your system is fully updated.
• Adjust Power Settings: Set your power plan to "High Performance" in Windows.
• Hardware Acceleration: Disable hardware acceleration in your browser and video players to see if it resolves the issue.

If the problem persists, it might be a hardware issue, so consider contacting AMD support.
