A:AnswerDepends on your graphics card if you’re playing on console you won’t be able to push higher then 60hz and you don’t need to do anything if your pc can push to 240fps
A:AnswerYes it works great, but if you're GPU is powerful enough, you don't even need any sync technology. 240hz with a PC pushing high framerate is so smooth the sync will only introduce input lag. I love this monitor.
