I've had a 144hz monitor for a while now, (Acer GN246HL to be exact) and at first I struggled to get it to 144hz, but eventually I got it working. I just moved into my college dorm room and had to disconnect all my cables to my desktop obviously. Upon reconnecting, I realized that the 144hz option doesnt even show up on change display settings in windows, or nvidia graphics panel. I know I'm using the right DVI-D cable because its the same cable I used to get 144hz before. The setting doesnt even show up. I've tried updating both the graphics drivers and monitor drivers to no avail.
I should mention my main monitor is 1920x1080 and I have two other 1920x1080 monitors that are 60hz on either side using the extend display mode.
Any help is greatly appreciated.. thanks!
