Intel display adapter issue on Aspire TC-885. monitors not working after sleep mode

RebelBob

I mistakenly installed the intel display adapter on my aspire tc-885, windows 11, and it seemed to be working fine for a while. Yesterday I thought I could not exit sleep mode because there was nothing on either of my 2 monitors. Pulled CMOS battery and replaced with new one so wondering if that could have messed up something?

Interestingly though I found that if used my Remote Desktop it worked, I.e. the system was indeed awake, and I could get to device manager that way. Now however if I reboot the pc neither monitor works. Device manager shows one generic monitor, not two. Detect says cannot identify another monitor. Have uninstalled the monitor driver and intel adapter and all hidden devices. Monitors still don't display. Anyone had problems with the intel adapter and if so, how do you fix it?

Was thinking maybe should download most recent bios but don't know how you execute it once downloaded and if that is a good idea anyway.

The Acer suppprt list of drivers isn't clear to me as to which one is for the display adapter. On,y one I see listed that might be it is vga driver? Also don't know to boot into safe mode. Will that give me a display?
