I recently bought a ASUS VG248QE from amazon and set it up with the DVI Dual link that it came with. Every setting says it's running 144hz, but for some reason it isn't actually running at 144hz. Windows settings, NVidia CP, and the monitor menu itself all say it's set to 144hz, but when testing on a site, and just looking at it, it's only running 60hz. I've tried 3 different wires. 2 Dual Link DVI's and a Display Port. This is the second monitor. I returned the first one thinking it was a problem with the monitor but this second is having the same problem so it has to be on my end somewhere. I've uninstalled my display drivers and reinstalled them. I don't know what else I can do.
