Hallo Forum,

I have an ASUS GTX1080TI STRIX OC graphic card and want to run an ACER PREDATOR XG270HU with it. The monitor is connected with a DisplayPort cable. On the PC there’s an up-to-date Windows 10 with the latest drivers installed.

Unfortunately I can’t select a WQHD (2560 x 1440) resolution with 144 Hz on the Nvidia control panel (version 378.78). The maximum I can select is 75 Hz; 144 Hz is not selectable, regardless of the resolution.

I have already tried a lot: Changed the HDMI port, changed the monitor cable, reinstalled the drivers, connected the monitor to another PC with the same configuration, etc.

Does anyone have an idea what to do? I’m out of ideas.

Thank you a lot.

That's weir, according to most websites this monitor should run at 144Hz. I have the same problem however. Bought it yesterday, but so far I can only get 75Hz out of it coupled with a GTX 1070
