Custom Resolution Utility (CRU)

[uhboof]

I have an AW2725DF, Nvidia RTX 3080, 8k 1.4 DP Cable. I have an elgato 4k capture card as well that is plugged in which i'll be cloning but I don't think it has much of a play on this as i've tried doing it without this plugged in

I want to play stretched and turn 2560x1440 to 1720x1080 360hz for better frames. I legit spent I would say about 10 hours trying to get this to work but this is my only hope now.

I am using Display ID 1.3 at the bottom and deleting everything else. I first copy the one that shows 1440p and 360hz, I delete that one and add a new one, paste, change resolution, I have tried with different timings but the resolution won't pop up once I try to change it. when I add a standard resolution of 1920x1080 with it, it works but only sets as desktop resolution and not active. I try to delete the monitor and "reset-all" but why is that resolution still there despite me deleting the entry????? I also tried SRE to delete 2k resolution off and it did nothing. I reinstalled my gpu and I believe the custom resolution was still there after. I kept changing things a bunch and eventually it disappeared but I can't get the resolution to show up on advanced display settings while getting it on active resolution. PLEASE HELP my head is actually hurting.
