I've been wondering what is the highest FPS my monitor can achieve so I've done some googling, but I'm still confused.
Basically what I've come to understand is your monitor's refresh rate is limited by your lowest spec.
My refresh rate is at 75 Hertz.
My response time is 20 ms, so if I do 1000/20=50 then it's saying my highest FPS should be 50 (I think).
I've also read that having Vsync can lower your FPS so I've turned that off, unless specified by an application.
I've been using a program called Fraps to monitor my FPS while playing games but I'm pretty sure that monitors what my GPU is outputting, not my monitor because I've seen it reach 300+.
I've also been using this performance tool from microsoft. On that I only top 60, which is showing me my FPS of my monitor, I'm assuming.
But why am I topped at 60, when my response time shows it should be limited to 50?
Even if I'm wrong with that then why is it capped at 60, when my refresh rate is 75 Hertz?
Response times doesn't have anything to do with max FPS, just the time it takes for the pixel to change colors. The greater the response time, the more ghosting there will be.
The refresh rate is basically what determines the FPS; this is a basic explanation as I am pretty sure it's a bit more technically complicated than that. Every 1Hz is data being transmitted from the video to the monitor per second. Technically speaking 75Hz means 75 times data is being sent to the screen or 75FPS. However, while there are some monitors that allow you to select 75Hz, some of them have internal electronics which converts any non-60Hz signal into a 60Hz signal which effectively eliminates the benefits of 75Hz.
