Hypervisor error 0x20001 occurs during a BSOD when two monitors are used.
Hypervisor error 0x20001 occurs during a BSOD when two monitors are used.
Maybe due to some reason the iGPU sent it. I verified it appears in Task Manager and Device Manager again, ran Windows Update, and even the AMD driver installation was happening unnoticed, despite not enabling device-specific downloads. My sensor panel remains connected via HDMI on the RTX 5070ti. I’ll check if the issues continue, but it seems iGPU might be involved. Yesterday, a BSOD occurred right after installing the AMD driver, so I had to perform a DDU afterward. My suspicion is that the two GPUs are clashing and the CPU can’t coordinate them, leading to this error. I see, perhaps that’s why I can still send a 1080p signal—Windows detected it that way, and it functions. The OSD menu also shows it’s receiving a 1080p stream, though nothing seems wrong on the screen itself. It could be some screen compression or the system is falsely reporting 1080p to both PC and user. I also set AIDA64 to render the sensor panel at 1920x1080 without issues, so everything looks fine there too. Essentially, everything works with the display, but something else in my PC is causing these problems. For now, I’ll keep it plugged into the RTX5070ti, since those errors started right after I chose to use the iGPU.
You can turn off the integrated graphics in the BIOS settings to test if it's not needed anymore.
It's been about a week since the last crash, and everything seems to be functioning properly now. It looks like the fix came from connecting the screen directly to the main GPU instead of using an iGPU. Performance hasn't shown much change, so I'm keeping it that way. The iGPU remains enabled, but unless the BSOD recurs, I can turn it off. For now, leaving it on doesn't seem necessary. Thanks for your support in resolving this issue.
