Hey,

I bought a set of two external monitors Kwumsy P2S for Windows and they don't work on my computer (no signal) unless I disable the Intel(R) UHD Graphics Display Adapter. After the disabling everything works correctly.
I went into the logs and I see a number of errors around oem46.inf, display.inf having a problem with starting:

Device PCI\VEN_8086&DEV_9BC4&SUBSYS_14321025&REV_05\3&11583659&0&10 had a problem starting.

Driver Name: oem46.inf
Class Guid: {4d36e968-e325-11ce-bfc1-08002be10318}
Service: igfx
Lower Filters:
Upper Filters:
Problem: 0x0
Problem Status: 0xC00000E5

I tried to reinstall the latest version of the Intel Graphics driver: 31.0.101.2115 (the version for 6th-10th generation and the version for 7th-10th generation) as well as I tried with the version 26.20.100.7985 recommended on the Acer Product Support page (unfortunately it doesn't seem like Acer tested the drivers with Windows 11).

    That's odd, neither the HDMI port or the miniDP port run off the Intel graphics, they are both off the RTX 2070. Here is the relevant portion of the block diagram:

    The builtin LCD runs off either the Nvidia or Intel (see the eDP cable connections), but the mDP, HDMI and DP Alt Mode on the TBT3 port all come directly off the Nvidia…
