My screen is 144hz 1920x1080. I (stupidly) bought a switch that only supports 1080p (to get my Nintendo Switch, PS4, and PC all on the same screen with one cord).
So when I boot my PC and put its video through the switch, the only available resolution to pick is a very low 1024x786 (and one lower).
When I go directly from the PC, I get all options including
So my question is, if I buy a switch that purports to pass through 4K signals, is that 'enough' and does HDMI work in such a way that it will sufficiently downgrade/sample my signal to my monitor's native resolution?
