ok I have an Acer Nitro 5 AN515-57 i bought last fall when my Gateway laptop's power fried somehow (all i had left was battery power that wouldn't recharge so i had like 2 hours to go through the entire pc to copy what files i didn't have already backed up, and it's plug still had a light on it so i assume the plug was fine...).
Anyway, I just unplugged my Nitro and put it on the bed while i cleaned my desk. When i plugged everything back into it and turned it on, the Acer boot logo came up on the laptop, then the login screen on my 2nd monitor (a BenQ), then it loaded everything on the BenQ and the laptop screen stayed dark. I checked the display settings (for extending the display, etc), it's like the laptop wasnt' even detected. I unplugged the HDMI, the screen switched to the Acer screen. Plugged the HDMI back in, and it was back to normal on both screens... So i reboot the pc to make sure it stays like that (I remember this happening before when i added a 1 TB SSD). Well it didn't stay like it should, it went back to the laptop screen staying dark after boot up. Go through all that a 2nd time, no difference (last time once i had it displaying both screens it stayed on both screens...). Then i get a notification there's an update for the intel display driver (the laptop screen, Nvidia 3060ti runs the BenQ). I install it and poof the laptop screen is back. Can anyone explain what the hell just happened? Am I stuck never unplugging this thing again? If there's no more Intel driver updates one day to reset w/e the hell it reset, how do i fix this when it happens again?
