A:AnswerConsoles typically have a capped framerate of 60fps making a 165hz monitor pointless essentially. The only way to utilize the 165hz would be to use a display port cord and not an hdmi which consoles don’t support.
A:AnswerDepends on what you’re using the monitor for. For PC gaming optimally you want a 144fps monitor with a low refresh rate to prevent input lag. For console, it will only run 60fps depending on if you have an older system. I know os4 pros run higher frame rates though, not entirely sure about Xbox.
A:AnswerFreesync will not work on nvidia graphics cards (the card you specified is a nvidia). It is for amd cards only. However, the 165 hz will work, and this monitor is still definitely a good choice for the rtx 2080.
