sorry… 170*

a year ago it did after installing drivers, and few days ago when i clean installed EOS
the settings displayed above 160hz, but above, it flickered!
so i thought i install the drivers, since i also want to play games and a lot of ppl say installing drivers should be the first thing 
… after installing the drivers everything above 120 was gone.
