A:AnswerYes it comes with the hardware to mount it via VESA. Do note, the VESA mount requires stand off screws from the back side of the monitor. It does include the stand off screws. Use it in a triple monitor setup and it’s been great.
A:AnswerThe recommended hz for this monitor is 144hz which xbox or any console doesn't support. You're around 60fps which means that's what your latency of refresh rate should be 60hz.
A:AnswerYes, however, keep in mind that this is only 1080p, so if you have the original Xbox One, yes it will 100% work! It will work with any other Xbox One, however, it won't show the 4K. The highest res is 1080p.
A:AnswerBasically, if I were to connect my Xbox and my resolution was off basically what would be a easier and better option to it if the settings don’t work
A:AnswerSince this is primarily considered for the use of 144hz, doesn't mean you can't use it at 60hz for your gameplay on console. (It would just be a waste of money) Since consoles only get 60fps the refresh latency can only be 60hz. Any higher and you can start to experience stuttering and massive screen tears.
