Vizio P502ui-b1e 4k TV. Strangeness
I bought this 4k TV because why not I needed a TV and it was cheap enough with a good enough response time for casual gaming. The Wierd thing is when I start a game and I switch to the monitors resolution I get this strange flickering like an old school TV you used to have to smack to get the lines to go away. I thought it might be an HDMI cable or sli bridge so I changed them both but nothing happened. I played with the setting on my desktop and this is what I found. If I set the res on the desktop to 4096 x 2160 and the rest in the game to the same I get the flickering. If I drop the res in game to 3840x2160 the flickering stops. Now if I set the desktop res to 3840x2160 and the same in game it flickers again. Basically both "4k" resolution of the desktop and game cannot be the same or it flickers. I have no idea why this is and was hoping maybe someone here could shed some light?
