Is there any solution to this strange behavior?

That's a monitor-specific issue, so you'll have to figure out if the timing parameters can affect the positioning. Normally the timing parameters don't affect positioning with digital signals. Many monitors will not accept refresh rates less than 50 Hz, so more than likely the monitor was not designed to handle low refresh rates and can't display them correctly.

First of all, HUGE appreciation to ToastyX for developing this Editor and providing immense support for all these years. My man, you are a rockstar!

I have been using a 34" LG 21:9 monitor for a few years now. This week, I picked up a couple more 34" LG 21:9 monitors (different models compared to the original) to build a triple-monitor setup. Each monitor is running at 2560x1080 @ 75 Hz. So, with NVIDIA Surround enabled, the displays should be running at 7680x1080 by my calculations. However, NVIDIA will only let me select 5760x1080 for some reason (as shown in one of the attachments.)

I'm not exactly computer savvy, so I have been following this YouTube guide to resolve the issue. I downloaded CRU and followed the steps described in the video, but I'm still only able to select 5760x1080 with NVIDIA Surround.

Please help! This 45 year old gamer is just so excited to FINALLY play on a triple monitor setup!

I attached some screenshot images that hopefully give you the information you need, but please let me know if you need anything else. Thank you so much!

That video doesn't explain the issue you're experiencing. The timing parameters and frequencies for the detailed resolutions you want to use with Surround must match exactly on all three monitors. The values aren't important. Just make them match.

NVIDIA's driver has a new bug that might cause the driver to crash on boot after using CRU. The bug only affects certain monitors, but you only need to edit either the old one or the new ones. If you're not able to edit either, then try installing NVIDIA driver version 471.11.

NVIDIA's driver also has a bug that causes the Surround to disable after rebooting when using EDID overrides, so you might have to enable Surround after every boot.

Matching the Detailed Resolutions settings did the trick! I was able to select the correct 21:9 resolution. Thank you, ToastyX!
However, after I rebooted, it went back to 5760x1080. Is there any fix or workaround to the bug that causes the Surround to disable after rebooting?

I looked at the extension block should i delete the 4k resolution in detailed resolutions(second resolution is 1440p)?
You can add the resolution you want as a detailed resolution on all three monitors. If the resolution already exists, make sure the timing parameters match exactly on all three monitors. You can delete higher resolutions if you don't need them.

Tried to add a resolution, but after using the restart 64 my pc freezes and need to hit the reset button, after rebooting it freezes again as soon as Windows starts.

Report the issue to NVIDIA. Their driver is broken. Try 471.11.

I don't know of a workaround. Does anything change if you uninstall GeForce Experience?

No luck, used DDU, installed 471.11, changed displays to 1080, hit the restart, screen went black and pc froze

Are all three monitors identical? Export a file with and without the changes and post them here. Try 466.77 also. I don't know the exact version where the problem started happening, but it's around that time that I started getting reports.

Hi, yes 3 identical monitors.
