problems with achieving120HZ on Samsung monitor

Recommended Posts

Posted · Original PosterOP

hey guys I'm having an issue with my Samsung c27fg70 monitor, I'm trying to get 120hz or above on it. when I plug a DP cable into him, flickers are showing and weird color problems occurring. when I plug 2 HDMI cables, the computer thinks I have 2 monitors and in the windows display setting, if I choose "monitor 1" it has 60HZ but if I choose "monitor 2" it shows 120HZ which is fine for me, the thing is suddenly my monitor freezes every once in a while. so I'm stuck with 1 HDMI cable plugged in making it 60HZ ): any tips?

my rig:

motherboared - Z270

ram - 16G

video card - 2 rx 480 (8G) (crossfire)

cpu - intel i5 - 7700k

sorry for my english (:

Did you try using only 1 GPU to see if you have the same problem ?
