1280x960 stretched not working when changed to 144hz

[GrantTuck1008]

Hi, I recently switched my monitor to 144hz and ever since I've switched, my Counter Strike: Global Offensive resolution messed up. I play 1280x960 stretched. My desktop resolution is 1920x1080 though and I've tried switching my desktop res to 1280x960 but it switches back to 60hz. And when I try changing it to 144hz, it switches to another random res. If there's anything you can do to help me, please let me know. I have an AMD Radeon R7 360 graphics card and a Acer GN246HL monitor. Thanks!

You need 1280x960 in the game's own settings.
