Hi. I have a Benq xl 2411z (with no displayport) and for my new GPU (RX 6750 XT) I needed an Adapter. First, I had the Issue that my Screen was black for some time on every Windows Start, and also on every Game start when the Game was in Fullscreen. Only a bit annoying, not too worse. I got this one fixed by plugging the Adapter into a USB 2.0 Port instead of 3.0. The Remaining Problem is, I get PC Crashes after Booting. BSOD code sometimes “IRQL NOT LESS OR EQUAL”, but not everytime. Monitor becomes dark after crash, and I have to shutdown and reboot. Happens pretty random. No clues to find in event manager, it only sais the usual 0x0000000a error Code. I tried to fix it by reinstalling the AMD and Chipset Driver, Windows Update and the usual DSM and SFC Scans. One thing I noticed is, since I use the Adapter my Device Manager does show white Question Marks at the Bottom Section where my USB Devices and the USB Devices Category is named to “Unknown” instead. https://ibb.co/rtZvyxN I don’t know if that is what causes the whole Problem, but I also cannot fix it without reinstalling Windows.

The IRQL NOT LESS OR EQUAL has nothing to do with the adapter. That error mostly comes up when something is wrong with a device driver, your device’s memory, or antivirus software on your device.
I’d suggest to check 1 stick of RAM (assuming you have 2) inserted in the motherboard.
DDU the AMD drivers and reinstall them clean. As you said you have a new GPU, it’s wise to re-install drivers clean.
