Acer Monitor XZ321QU - Display max at 120hz ?

Hi everyone,

I just bought this monitor Acer XZ321QU from our local store in Mel-Australia. Apparently, I connected to my PC and only can get 120Hz from Display port cable (supply from manufacture) to my Asus GTX-760 Striker 4 GB and 60 Hz from HDMI 2.0 (cable from manufacture). I'm sure that I hook into the HDMI is not MHL port(60Hz).

- My Nvidia's driver is up-to-date on 26 Nov 19. CPU i5, 16GB Ram 2666. Windows 10 Home 64 bit (up-to-date driver)

Is there anyone has idea why it does not display at 144 Hz but 120 Hz max on display port. I also could not find any driver support for windows 10 but windows 8 on Acer website. ??

Regards

Good Morning stevenaus !

First, Windows 10 manages monitor controllers differently, not using standard "drivers" like other versions of Windows.

The frequency issue by default on HDMi will only go back to 120Hz.
144Hz natively only via DP.

Hi MaClane,

As mentioned in my case, it showed only 120 Hz on DP(manufacture’s cable) and only 60Hz on HDMI(manufacture’s cable). I don’t know if this is windows driver I ssue or my graphic card issue or cable issue !!
