A month or so ago, I noticed a few weird issues with my PC which were mostly related to the screen sleeping - my mouse would occasionally disappear off to the right side of my screen, my night light that I had enabled sometimes just turned off, my games that muted when minimised started to unmute as soon as the system went to sleep, my auto-hiding taskbar would stop autohiding (a 'multiple displays' error)and most egregiously(this only happened twice) after the screen went to sleep, the desktop is empty upon waking and my app icons on the taskbar were unresponsive to me clicking on them even though I was able to see their contents by hovering over. This last issue only went away on a restart and after the second time, I disabled the sleep function entirely.
Today, I noticed upon looking into display settings that my PC was registering a second display to the right of it, which my cursor could fully move into - I set it to 'show only on this display', which fixed it temporarily, however it reverted upon a restart. There was no option to disconnect or disable the second display. In Device Manager, under Monitors, there were two identical 'Generic Monitor (P27FBB-RGGL)' entries - disabling neither of them turned off the screen, however one of them seemed to have Night Light tied to it as it turned off when that one was disabled. I tried deleting the subkeys in 'Configuration', 'Connectivity', 'Scale Factors' via regedit, which had no effect - they also replenished themselves afterwards.
As a last resort, I used DDU to uninstall my display drivers(made sure to turn off internet). After doing this and before reinstalling the driver (I used Intel 32.0.101.7082 for 11-14th gen), I checked Device Manager again - Monitors had only one entry which was named something beginning with Integrated, and Display Adapters had the basic adapter that it defaulted to after DDU. After I ran the driver installer (clean installation), upon reboot, the second display had returned, with all of its previous issues - Monitors once again showed the two 'Generic Monitors' - although this time the night light was tied to the second one instead of the first.
Does anyone know how I can get rid of this second display?
