So today all of a sudden my main monitor freaked out and is stuck to a maximum resolution of 1024 by 768 instead of 1920 by 1080. I have a GTX 1070 and a Dell S2740L monitor.
I already: uninstalled and reinstalled the Nvidia drivers, added a custom resolution (which windows didn't like), unplugged and replugged the monitors, restarted my pc, updated drivers, installed driver via cd that came with my card, checked monitor settings.
I'm running out of options here.
Edit: for some reason the Nvidia Control panel thinks my problematic monitor is DVI when it's HDMI. Same thing happened to my DVI monitor being read as HDMI.
