Hello, my brother gave me his G2460PF monitor and i'm trying to set it to 144Hz using DVI-D(My graphics card doesn't support Display Port so i'm using DVI-D) on my computer. Specs : GTX 750 (non Ti) I3-3220 3.3Ghz 4Gb Ram. But it's not working i've tried setting it from NVIDIA panel aswell as from desktop. I was able to achieve 75 Hz (setting my resolution to 1280x1024), but if i try to set it from native resolution (1920x1080) it doesn't work i can only choose from (100Hz;120Hz;144Hz) setting it between 100Hz-120Hz works but my screen looks all messed up ([video="https://www.youtube.com/watch?v=o1WeBCk4oOw"]https://www.youtube.com/watch?v=o1WeBCk4oOw[/video]), if i set it to 144Hz my screen goes dark for 10~20Secs and it reverts back to 60Hz. I've tried setting custom resolutions from NVIDIA but that didn't help.
What's wrong ?
