Hi, I own a Aopen Acer 32Hc1Q monitor which is a 1440p 144hz display.
I have a gtx 1060 GPU. When I use DVI-D, it works properly but of course it only supports up to 75Hz at that resolution. So, I bought a DP cable but now it doesn't give me display.
I somehow managed to get the display two days ago when I connected both, set the input from monitor menu to auto. Then I disabled the DVI connection from Nvidia control panel and the DP was working fine at 144Hz.
But there is some kind of bug. It doesn't work everytime. I tried doing a lot of stuff but I don't know why my GPU or monitor can't get the display output from DP port even though I checked all the DP ports on my GPU.
