This can be used as monitor to go with your xbox, ps4, etc. Use the HDMI port to connect it to a console of your choice.
However, you would be wasting your money. This is $$ primarily because it has 144hz, 1ms, and gsync. none of these are available on console anyway, so you might as well buy a cheaper monitor - for example, something with IPS, 5ms or better response time 60hz or better refresh rate. You should be able to get one with all those three criteria for well under $200.
