You have us! Seems there are a few willing to assist. Breaking things is an excellent opportunity to learn! My IT career was kicked off by breaking computers!

I am not sure if I missed something in the thread, but did you try going to settings > peripheral devices > screen, and changing the resolution? I have seen mentioned flipping the video card selection to or from VGA and back can help.

I have loaded PopOS before, but did not really care for it and am now on Mint. I would be happy to load it up on a system tonight and help you troubleshoot a bit as I have a spare small PC with a 1080 in it.

Edit: Ah, I see that you did try and it won’t let you change it. I can load Pop up anyways to have it handy in case you reach out for help. I’ll try and load the specific release you did.
