A:AnswerI managed to use 144hz with both monitors I ordered with HDMI. I did upgrade to display port since my graphics card has 3 DP, but both work flawlessly.
A:AnswerNo, this Monitor stays at 144 or below. Refresh rate is typically locked at a cap from the manufacturer. If you want higher refresh rates, aim for a 200+ refresh rate monitor.
A:AnswerYeah, as long as you have HDMI or DisplayPort, but it comes with an HDMI. Not sure if the included cord is HDMI 2.0 though, since I use DisplayPort, so it may not be capable of 144hz.
