Hi guys, yesterday i've bought this monitor and tried to set the refresh rate to 75hz but it's stuck on 60hz. I can't get past this limit even with user manual saying that 75hz is possible with 1920 x 1080. The only resolution that supports higher refresh rate (according to my GPU) is 1152x864. Already tried connecting it with HDMI, DisplayPort and VGA. I'm using MSI GTX 1060 6GB.
