Hi, this is my issue. The 144 hz simply wont show up for me. I can only do 59 hz and 60 hz. ASRock z87 killer Ati Radeon 6950 Ben q 144 hz monitor Dvi dual link cable Windows 10 I reinstalled the drivers. Is there a reason why this is happening? Is the 144 hz option limited to certain cards? I know I have the right monitor and cable. I am not sure what I overlooked. Thank you very much for the help.
