Custom Resolution Utility (CRU)

[Dinkles]

Hey,
I’m wondering if anyone can help me.

I have a AG493UCX monitor with a 5120x1440@120hz native resolution.

However, the monitor/windows appears to believe the native resolution is 3840x1080 which is a huge issue for a number of reasons.

For example,
When I switch to my other monitor and return to this monitor (via NCP) windows resets the resolution to 3840x1080.

When I play a game using NIS the game is actually downscaled to 3840x1080 then stretched up to 5120x1440 which looks beyond awful and really makes NIS unusable.

The monitor works perfectly at 5120x1440@120hz
The monitors native resolution is 5120x1440@120hz
I am using DP

The monitor basically tells windows (for some unknown reason) that its native res is 3840x1080 and this causes me so many issues. If there is any way to use CRU to change the “recommended” resolution or simply have it always default to 5120 that would be great.

I tried using CRU and simply changing the resolutions to 5120, however the numbers turn red and don’t allow me to save them, even though I am using the correct resolution and timings.

I googled the issue and found a Reddit post that led here, is there anyone here who can help me out with how to get this 5120x1440 monitor to simply recognise and register its actual “recommended” resolution by default.

That’s folks, and also thanks for creating CRU as I just used it on my C3 to delete the 4k resolutions that were also causing issues with scaling, so thanks for that info, the tool and the guide.
