Custom Resolution Utility (CRU)

I'm afraid it's monitor limitation. I tried default 60Hz resolution that has only 1/3 of pixel clock, but screen still goes black below 48?

I've been using CRU since I bought an OLED C2 in early 2023. The software is exceptional, it helped me set the 3840x1600 ultrawide resolution as native in the NVIDIA control panel

About that, since the latest 556.12 driver, the 3840x1600 ultrawide resolution is locked at 60Hz only

There is nothing wrong with the CRU, just the NVIDIA drivers are problematic, as always

Several other users are reporting to NVIDIA, including me, waiting for a solution

Yup! Same setup, so I'm on the same boat.

Were you able to find a solution? A downgrade? Or do we wait for a new driver?

Integer scaling should give you access to the same refresh rates as your native resolution.

Hello!,

Whenever I use CRU to remove TV resolutions my NVCP goes away. Does anyone know how to fix this? My ultimate goal is to use DLDSR at the correct resolution but it doesn't scale correctly because of the TV resolutions.

TL;DR.

Is there any way for me to use CRU to remove TV resolutions without making my NVCP non functional?

Thank you.

That's an NVIDIA control panel bug that you should report to NVIDIA. Also if you are removing 4K resolutions, make sure that you remove them from the HDMI data block as well.

Hi, I have a question. Is there a way to see what numbers were selected for an active timing that the video card created, e.g. with its inbuilt custom resolution utility? CRU is a calculator that can provide numbers but it can't show what is in use.

I looked in the Windows Registry section for the Intel graphics driver, but I don't see anything obvious that involves timing-related information.

I had this bug few times last week when I was messing with VRR range or removed some useless resolutions.
I think this bug happens randomly. For example I've change VRR window 5 times and after 6th change NVCP goes away. I've lost like 10h trying to figure out what is going on, but I figured out that you need to uninstall your Nvidia drivers with DDU, install fresh driver again and the same change in CRU will work next time.

I need some help. I have a TCL C855, and I use as my monitor. NVIDIA GPU using a HDMi 2.1.
My problem is, when I try to use the DSR feature, he uses the 4096x2160 resolution with 24hz to multiple, and downsample to it.
I want the driver to use the 3840x2160 120hz.

I downloaded the CRU, and deleted the 4096x2160 24hz in the CTA-861 Extension Block. But this resolution still appears on the Nvidia Control Panel.

What else do I need to do, to complete erase this resolution?

Did you delete it from the HDMI data block as well?

I don't know if there is a way to get the timing parameters from Windows. AMD shows the current timing in their control panel. NVIDIA shows the current timing when adding a custom resolution. I don't know about Intel.
