Eyefinity question only. (I can't find where to change the resolution out of Eyefinity, either. Not within the Adrenalin software)

Noob question, I know. Using my son's 7900XTX temporarily and I have three displays. I'm trying to finish Horizon Forbidden West, which will not play at 11520x2160 (on AMD nor NVidia. Crashes every time the game starts). I have been playing at 7680x1440 on my RTX 4090, but it's gotta go back for RMA and using my son's for the time being. I can't figure out how to change the resolution once I turn on Eyefinity though. It automatically goes to 3x4K. There is no option to add custom resolutions to an Eyefinity setup. Within Windows I can easily select 2560x1440 on all displays, but as soon as I turn on Eyefinity, it goes back to 3x4K.

I've tried messing around with Custom Resolution Utility, too. But it doesn't let me create resolutions that go beyond typical display resolutions (ie, typing in 7680), at least not anywhere I've been able to find. I think it should be a simple matter of finding where to change it within the Adrenalin software, but I can't find it.

edit: It seems to be a specific AMD driver thing since I've found another thread on LTT that had the same problem from 2022, and no one responding, no solution listed, etc. I've even gone so far as to use CRU and delete all 3840 resolutions. I have no problem displaying 2560x1440, but even with the 3840 resolutions gone, Adrenalin gives me 4098x768. All the rest of the resolutions are back to the regular options.

First things fist, did you run DDU to remove all GPU drivers(intel, AMD and Nvidia) in Safe Mode, to manually install the latest GPU driver sourced from AMD's support site in an elevated command?

yes, but completely irrelevant. Uninstalling NVidia drivers or not isn't going to change where to look for trying to change an Eyefinity resolution.
