Question Triple Ultrawide Monitor - Low Resolution

[Whiteman7]

Good Morning everyone
I need your help m8s ...
I have a setup of three Ultrawide Monitors (3440*1440) , all set at 100Hz and on display port 1.4 everyone
I am trying to make them as one through Nvidia Control Panel but it gives me only the choice of Resolution 3072*768 at 60 Hz instead of 10320*1440

I would appreciate any of your help
Thnx in advance

You should be able to run 1440p at 100Hz across 3 panels with that RTX3080. Does disabling G-Sync and VRR on both the monitors and the software alleviate the issue?

First I'd check and see if your motherboard has any BIOS versions pending update. Then, I'd advise you run DDU to remove all GPU drivers(Intel, AMD and Nvidia) in Safe Mode, then manually reinstall the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

For surround to work, all monitors need to use the exact same timings. Since you are using 3 different models they will not have exactly the same timing definition for their 3440 × 1440 @ 100 Hz formats.

You need to use CRU to edit the 3440 × 1440 @ 100 Hz profiles to make them all the same settings (front porch, back porch, etc). It will probably be located somewhere in the CTA-861 extension blocks.
