I'm pushing the p50-c1 as a pc monitor with two gtx980ti. No problem at all for gaming at [email protected] or sometimes [email protected] I can set the desktop at those resolution also. Little advice if using the set as pc monitor, is connect the pc to hdmi 2 input. Using hdmi 5 input has cause screen blackout trouble for me if I use vlc media player to watch 4k video. Also for some reason 4k videos stutter or judder with vlc, but not 1080p video. I downloaded a free media player called potplayer 64 bit and the 4k videos played fine. Advice number 2 is use the included vizio hdmi cord. I ordered a 6 foot high speed 18gp/s hdmi cable with RedMere Technology chip built in and I also ordered a 6 foot 1.2a display port to 18gp/s hdmi conversion cable from monoprice. I'm hopeing these cables have better connection for this panel and pc. The links are here if your interested.
My xboxone, 360, ps3, ps4, wiiu, nvidia shield and steam link are connect to my lg oled ec9300 in the bedroom. My p50-c1 is a monitor for mac pro and pc.
Hey guy, if you're watching movies on it with your computer, you absolutely need to get MPC-HC along with MadVR. MadVR is a crazy awesome renderer that can take full advantage of all of a 980ti's processing power and then some (I know because I also have dual 980ti's). If you have a colorimeter you can even make 3DLut's for it. It's generally considered to be superior to just about any external video processor and is serious enough that Calman has MadVR 3Dlut creation built into it's enthusiast edition.
