I recently booted from a USB to test a kernel I was working on. (not related, but it had an error leading it to crash. i located it in the code.) Later, i set the BIOS settings back to the ones I had before booting from this USB. The computer booted, but the screen no longer showed anything. I switched to a VGA cable, which worked (the computer showed the screen, and I logged in.) I am posting this from the computer mentioned in the post via VGA.
My computer is a Dell XPS 8900 (Nvidia GTX 745, Intel i7-6700, 16GB RAM). It totally worked before I ran the USB.
I'm suspicious about the USB drive boot; it operated in VGA text-mode so I think the monitor now expects that.
Please help, as it would be optimal if I ran in DVI. Thanks.
EDIT: My monitor is a ProArt 1920x1200 1080p.
