Custom Resolution Utility (CRU)

Quote:The only way around this would involve losing 360 Hz.

I agree. Please tell me how to make 60,000 and 120,000?

You need to edit the registry as described here: https://www.reddit.com/r/OLED_Gaming/com...and_other/

That will disable using multiple heads internally, which will allow EDID overrides to work, but you will be limited to around 1350 MHz pixel clock.

Active is in the detailed resolution dialog. In Radeon Settings, the resolution is the desktop resolution and the timing display is the active signal resolution. CRU only deals with the active signal resolution, and the desktop resolution should always match if GPU scaling is disabled and you set the resolution through list all modes instead of the display settings.

Either the monitor isn't handling the resolution correctly, or the adapter is not converting the resolution correctly. Did that also happen with the Insignia adapter?

Hello and thank you for this really useful software!

I have a question regarding VRR. I have an AMD gpu and a 4k60 monitor with a default VRR of 48-60.

Thanks to the CRU, I increased the VRR to 30-60 without any issue. However when I overclock the vertical refresh rate, the VRR is broken even if I keep it at default, and the games stutter a lot even at a stable frame rate inside and outside the VRR range.

The monitor can go up to 80hz without issue except in game (it is advertised to go 23-80). For reference, here are the specs: https://www.usa.philips.com/c-p/436M6VBP...h-ambiglow

Also, my gpu is rx 6800 xt. To explain, I would like to have the highest refresh rate for every day use and keep the VRR working for games (by locking the frame rate at 60 in-game).

Do you think there is anything I can do to make the VRR and overclock work together?

I'm not entirely sure where to post this but I'm having trouble setting up specific custom resolutions on CRU.
I'm using this on a 1920x1080 120 hz laptop with a relatively recent AMD iGPU.
I can't seem to add a custom resolution of 1080x1080 (yes 1:1 aspect ratio), when I try adding it in the custom resolution option, one of the height/width option would turn red not allowing me to proceed.
I was curious if I'm doing something wrong, or if there is some other way of getting this to work.
Thanks.

The VRR range must include the refresh rate you're using for VRR to activate, so the VRR range would need to be set to 30-80 Hz or 48-80 Hz. If the TV can't handle VRR correctly at 80 Hz, then you'll have to set the refresh rate to 60 Hz in the game's settings, or switch to 60 Hz before running the game if it uses the desktop refresh rate.

You should really read the first post before using this software. Also you're better off using SRE in this case: https://www.monitortests.com/forum/Threa...Editor-SRE

Thank you very much! I confirm the working solution!!!

Hey ToastyX, I have a question regarding VRR/FreeSync/G-Sync support when using a USB-C dock with a DisplayPort 1.4 output.

I’m using a laptop with an Nvidia 4070 and a monitor that supports FreeSync Premium, but only via DisplayPort input (it also has 2x HDMI 2.0 ports). When I connect the laptop directly to the monitor with a USB-C to DisplayPort cable, G-Sync works perfectly.

However, I’d like to use a USB-C docking station that has a DP 1.4 output, and I want to achieve the same G-Sync support through it. Is there a way to force VRR/FreeSync/G-Sync via the dock using CRU.exe?

For reference, I was previously able to force enable FreeSync on HDMI output using CRU, and for a moment Nvidia Control Panel showed G-Sync as supported. But the monitor kept flickering, which I assume is due to hardware limitations of HDMI 2.0. So now I’m mainly trying to get G-Sync to show up as supported in the Control Panel when using the dock—even if it's just a placebo.

Any guidance would be appreciated!
