Why can’t I set the frequency to 144Hz on my XL2411/XL2411P?
Please check the following:
- Make sure your graphics card has a DVI port and a DVI Dual Link cable is used.
- Make sure the BenQ bundled DVI cable is used.
Note: Only DVI Dual Link supports 144Hz on the XL2411.
Both DVI Dual Link and DisplayPort 1.2 support 144Hz on the XL2411P.
