I am trying to use a LGUH8500 4K tv with my PC which has a GTX 1080TI in it. I am using HDMI 2.0 cable so I am confused. In the display settings on windows it says 1080p is "reccomended" and in the nvidia control panel it says that 1080p is the "native" resolution. I am able to set the resolution to 4k in the nvidia control but then whenever I go into my pc settings in windows my tv loses signal so I have to blindly find the x to close the window to get signal back. I have already tried reinstalling the graphics drivers.
