Question PC thinks monitor is plugged into DVI, limited to 1024x768 after re-plugging in HDMI (NVIDIA Geforce RTX 3060)

[ToriInCan]

Sometimes when I work from home, I'll unplug my monitor's HDMI cable from my home PC and plug my work laptop into the monitor so I can have a full size screen. Have never had a problem switching back to my desktop after doing that, except after doing it last week. I do use the HDMI slot connected to my graphics card (NVIDIA GeForce RTX 3060). The next time I turned my PC on, the display was stretched out and zoomed way in, and I saw when going to display settings that I was limited to a resolution of 1024x768. I reinstalled and updated the NVIDIA driver, restarted, and no luck, I'm still stuck with this. Updated Windows which also did nothing. Can't change the resolution in either Windows or the NVIDIA Control Panel. It also says that my monitor is plugged into DVI, which it's not, it's definitely HDMI... I tried a different HDMI cable and no luck with that either. Help?

Welcome to the forums, newcomer!

I reinstalled and updated the NVIDIA driver, restarted, and no luck, I'm still stuck with this.
Use DDU to remove all GPU drivers(intel, AMD and Nvidia) in Safe Mode, then manually install the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.
