4k tv resolution issue
I'm running an LG 4k UHD tv with a GTX 1080.
The first day I brought it home I was able to set the proper 3840x2160 resolution but then I updated the driver. Now anytime I set that resolution, starting from the standard 1920x1080, I get a black screen.
It's not the TV because when I set for a higher hertz it said invalid format. Just setting the resolution delivers a black screen.
I tried to revert to the previous driver and it was able to get a screen but after a few seconds it went black again.
Testing with interlaced instead of Progressive I was able to get the 3840x2160 but the screen was vibrating.
