60hz on 75hz monitor

[olekbf3]

Sorry if my english isn't perfect.

I bought AOC 22V2Q and it is 75hz 5ms monitor IPS. It is quite nice for this price (that's what they say) but i am disappointed about one thing. While i try to play games on 60hz the movement is a bit ... how to say .. blurry or slower despite stable 60fps.

I was using for years LG TN monitor what was 75hz and 5ms too but i was using it as 60hz and i haven't noticed any problems like that.

on AOC as 75hz is all ok but sometimes i need to play on 60hz because i can't get stable 75fps. I use also gtx 970 windforce 3 and it is plugged by displayport.

why is this problem? isn't 5ms meaning same for both TN and IPS? How could i fix this problem? Is it possible to use AOC as 60hz without problem?
