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).
