Assistance with EDID edit for Nvidia surround Acer x34p + 2 LG 27" monitors

Hi all,



My current setup is triple monitor running of a single 2080ti on intel 9900K.

Left: LG 27GL850-B 27" 2560 x 1440p (capable of 144hz but set to 120hz gsync)

Centre: Acer predator X34P 34" 3440 x 1440 (Stock is 100hz but overclocked via menu settings to 120hz gsync)

Right: LG 27GL850-B 27" 2560 x 1440 (capable of 144hz but set to 120hz gsync)

I wanted to use Nvidia Surround but running into that issue where trying to do it gives that random resolution 3072x768 with 60hz refresh rate maximum.

I did reading online and saw that people were using Custom resolution utility (CRU) app and modifying EDID on the affected problem monitor to make nvidia recognise the correct resolution.

I have tried experimenting (replicating the known 120hz settings in the Acer X34p profile within the CRU app and trying to add that everywhere) in the hopes nvidia surround will pick it up correctly and add the monitor resolutions correctly.

Attached some screenshots to show whats going on. Anyone know or can guide me on how to fix this up?

Included what I can see in the Acer X34 profile and the LG 27GL850-B profile in Custom Resolution Utility.

Thank you for your time.
