A:AnswerYes it should as it is HDMI 2.0, I use it with my X1S and it's great! Unfortunately that will only be at 30Hz, to take full advantage of this monitor you'd need something that outputs via DisplayPort as it supports 4k @ 60hz and the great Freesync technology!
A:AnswerI purchased this yesterday and it indeed does work beautifully with a PS4 Pro. HDMI Port 2 is a HDMI 2.0 port. Do not believe what people are saying about it doesnt work with HDMI etc cause they are wrong or using the wrong port. On does 30 and the other does 60. Great monitor for the price. Very happy with my purchase.
A:AnswerYou need a video card (GPU) that support 4k output. The GPU will need to have DisplayPort 1.2 or higher which will support native 4k @ 60FPS or GPU cards the have HDMI 2.0 support.
