A:AnswerYes. This monitor will support HD and 4K HDMI inputs from any video source. My concern would be that you also need a sound bar or other audio device.
A:AnswerYea it will display your games in native 4K. However it does not support HDR and only has 1 hdmi port that is capable of 60 frames per second. It’s a really good monitor other than that.
A:AnswerYes this monitor has 1 display port and 3 hdmi ports. Only one of the hdmi ports supports 4k at 60hz the others are 4k 30hz. I have a Desktop PC a ps4 and a switch plugged into it.
