A:AnswerIt can be set to actually reduce lag and will work in conjunction with the right video card that has the new reduced latency settings. It is a 165Hz monitor.
A:AnswerYes i have my Xbox One hooked up to it using a high speed HDMI cable. Be sure to go into your Xbox settings once installed and allow for 120hz refresh rate
A:AnswerFPS is determined by your CPU and Graphics card, and ping is determined mostly by your internet connection in relation to the game server. These are not related to monitors.
A:AnswerYes you can hook up an Xbox to it. I have my Xbox One hooked up using a high speed HDMI Cable. Go into the Xbox settings and allow for 120hz refresh also
A:AnswerI have noticed a decent amount of Back light Bleed on this monitor. I do recommend NOT using the FPS setting on this for Xbox and using the Custom User settings to get the best picture on an Xbox. Also be sure to go into your Xbox settings and allow for 120hz :)
A:AnswerNot entirely sure what you're getting at, but your system should run a 1080p monitor without a problem. You might not see full 144 fps with that card on newer games
