ASUS VG248QE - can't switch to 144hz

[Wojii]

Hi there.

I have been fighting with it whole day, just got second-hand ASUS VG248QE 144hz. It does work on all refresh rates besides 144hz. Whenever, I try to switch to 144hz or play league of legends (on any refresh rate) it turns to that weird grey flickering screen. However, if I alt+F4 when lol is opened then it will revert back to desktop.

The same is when switching to 144hz just have to wait until revert changes time out to get normal desktop.

I tried playing Doom Eternal, Valorant, Path of Exile and it does work at 120hz.

Fresh install of drivers didn’t help.

 

I DVI dual-link for this screen and ordered dp cable to see if that’s the issue.

I got another 2 screens connected (60hz) and both work without any issues at the same time.

 

I’m out of ideas how to troubleshoot any suggestions?

Thank you

what happens if you disconnect one or 2 of the other screens?

looks like what happens when I use the single link DVI port on my dock and try and run 144hz, 120hz works fine as well but 144hz is black and sometimes static like you described, could be the cable or port. Have you tried Displayport on the monitor?

I said said I just ordered one should have it tomorrow. I double checked cable and it is dual link. Port on gpu should be ok as it is brand new card (less than month). Maybe it is port on the screen. I will update with new cables tomorrow.

Thank you for you help. It was the cable/port. As soon I swapped to dp it is working without any issues.
