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
