If anyone can help me get 2304x1440 into my choices for custom resolutions that would be amazing as this is driving me crazy.

It's this issue mentioned in the first post:

Please report this issue to NVIDIA. 5000-series GPUs have a higher single-head limit. 3000/4000-series GPUs can use SRE for custom GPU-scaled resolutions but not custom refresh rates: https://www.monitortests.com/forum/Threa...Editor-SRE
The only way CRU could have worked before is either you disabled DSC in the monitor or you used this registry tweak:

That would disable 360 Hz at the native resolution though.

Some how I have the custom resolution inside the game application (It shows 2560x1440, but this is definitely the 2304x1440 I put in CRU), yet it does not show up in my nvidia or windows display. Yet my mouse alignment is very much off.
Hello, I have an issue with NVIDIA Control Panel after using the CRU utility to remove unwanted resolutions (4096x2160) from my monitor. After removing all entries in CRU of 4096x2160 the NVIDIA Control Panel loses most of it's settings leaving me unable to make modifications to my configurations. Upon reinstalling the NVIDIA driver or undoing the modifications using reset-all the missing settings return. Any help with this issue would be greatly appreciated.
My PC:
Monitor - LG C2 42" OLED
GPU - RTX 4090
Cable - HDMI 2.1
CRU Version - Latest 1.5.3
Driver Version - 581.08

You should report that to NVIDIA because it's a bug in their driver. Someone mentioned switching from GPU scaling to display scaling in the NVIDIA control panel before using CRU might avoid the problem.
I'm trying to edit the VRR/LFC range for my monitor. It looks like there's at least 3 different locations to do so, does anyone know the differences?
- Display Properties -> Range Limits -> V Rate
- Extension Block -> FreeSync Range
- Extension Block -> HDMI 2.1 Support -> Variable Refresh Rate

DisplayPort adaptive sync uses the range limits.
AMD FreeSync uses the FreeSync data block. NVIDIA ignores this.
HDMI VRR uses the HDMI 2.x data block.
Hello!
I need help with working the display scaling stuff. I would like to be able to use true stretched res and be able to make my monitor native to an odd res maybe something like 1550. I’ve done this process before on another monitor I've used in the past and I've done everything the exact same. Everything goes perfectly until I want to use the new res I picked out. When I go to nvidia it would normally show that I can’t use both GPU scaling and Display but after I used “restart64.exe” my Display option was gone and got swapped to GPU only. I cant use native res because of this and it does look like my monitor should be able to use CRU because I’m always given the option to choose between Display and GPU until I press “restart64.exe”. I went back and tried this on a different monitor and it worked just fine but it wont work for the one I want.
Specs:
Monitor- Dell S2522HG
GPU- 3070
CPU- Ryzen 5800x
(The images below show with and without Display. The image that shows display scaling as an option is before I press “restart64.exe”. The one with GPU is after I press “restart64.exe” and it only locks it at GPU and no longer gives me the option to use Display.)
If there is a way to fix this or something I’d love to know. Thank you.

You need to show what you're doing in CRU because I have nothing to go on. Also the native resolution is never scaled by the GPU regardless of what the control panel says. The display scaling option will only appear if there is a lower resolution to scale.

Oh you're right sorry.
I'm trying to get a new resolutions by making it my native resolutions. What I've been doing is I go to extension blocks and copy one of the detailed resolutions (the one with the Hz I normally use which is the highest). Then delete all extension blocks, delete all standard resolutions and detailed resolutions. then I make a new standard resolutions that matches my monitor but leave it at 60Hz. Then I make a new Detailed resolutions and paste what I took from the extension block and instead of having 1920 x 1080 I swap it to something I want.
I assume I'm doing something wrong because I am removing a lot of stuff. I've followed videos and it is what they say to do.
When I have done this in the past it worked and showed that my native resolution of 1920 x 1080 was no longer recommended and the one that was now my new recommended was the one I just made on CRU. But I cant find the new res I made.
