There's a bandwidth limit.

Im using a dvi d (single link) to hdmi adapter on my rx 6600, i used to be able to oc my bx 2440 monitor to 75hz with my gtx 970 but now it won't let me overclock higher than 71 because of the pixel clock limit that isn't getting patched right by the ati clock patcher, probably because the card doesn't support dvi.. Any tips??

The patcher is supposed to work for that situation, but you might not need the patcher anyway. You can use "Exact reduced" timing to make 1920x1080 @ 75 Hz exactly 165 MHz pixel clock, and if that timing doesn't work for your monitor, you can add an HDMI data block in a CTA-861 extension block to go beyond 165 MHz.

Got a problem here with the latest Nvidia drivers - the moment i modify anything with CRU, the nvidia control panel loses 90% of its features.

Delete the changes in CRU, restart64 and they come back.

Anyone seen this before, and knows of a fix?

4K 70Hz so nothing drastic - change/breakage occurs when i adjust in detailed resolutions, or add in the extension block

I figured this one out - if 'image scaling' is enabled, using CRU breaks the control panel

If you end up in this situation, delete your profile in CRU, restart driver

Open NVCP, disable image scaling in '3D settings' and under 'adjust desktop size and position' make sure scaling is set to occur on display and not GPU

Thanks alot, it worked with Exact reduced timings.

I found this in trying to get my PC to display on my Samsung Odyssey Neo G9. It's shown up exactly twice at 240 hz but it doesn't want to show up at max resolution at that refresh rate. Your tool looks amazing, but i'm not sure how to use it. Any assist would be amazing

CRU is not for fixing issues like this. 240 Hz should work out of the box, so something is wrong. 5120x1440 @ 240 Hz requires DisplayPort 1.4 or HDMI 2.1 with Display Stream Compression (DSC), so the GPU must support that, and the cable needs to be good enough to handle the bandwidth required, or it might negotiate a lower speed.

Toasty beat me to it, but most likely your GPU (or possibly cabling) doesnt support the required DP/HDMI standards required

You need to set the native resolution and then see what refresh rate you can run, and compare HDMI and DP with your graphics card - quite often they're not equal.

New LG C1 owner here, using it for PC gaming. What a handy tool! I do have an issue I am hoping I can get some information on (or resolution too). I think I am hitting a bug with CRU 1.5.1

My setup:
Win11
Nvidia 3090
Latest Nvidia 516.59 Gaming Drivers
HDMI input set to "PC mode" in LG menu

Bug Replication Steps
1. Use any HDMI input
2. Enable VRR/Gsync in LG's Game Optimizer menu
3. In CRU edit HDR Static Metadata and set Max and Avg Luminance of 128 (it seems like ANY edit will do. I tried deleting 4096 resolutions too).
4. Reboot
5. Disable VRR/Gsync in LG's Game Optimizer menu
Result: black screen. TV no longer receiving a signal

More findings: if I re-enable VRR/Gsync in Game Optimizer after I get the black screen, the signal to the computer comes back. Also, if I first disable Gsync in Nvidia Control Panel and then disable VRR/Gsync in Game Optimizer the signal from the computer to the TV is not lost.

Things I have tried.
-reinstall nvidia drivers
-tried different HDMI ports
-tried new 2.1 certified HDMI cable

Any ideas?

Hello. Upgraded old Sharp TV to new LG C1. Used to hook up HTPC > Denon AVR-X3400H > TV while getting great sound options (DTS, 5.1, etc). New C1 uses eARC, and from looking at reddit threads, there is an issue where LG limits the sound to stereo. That lead me to a proposed fix using CRU, but I am still having issues.

TV: LG C1, HDMI port 4 set to PC mode
Receiver: Denon AVR-X3400H - newest firmware
GPU: AMD RX 480. Drivers - 22.6.1 released 06/22/2022
Connecting to LG C1 via HDMI 2.1 cable

I believed I followed all of the steps of drilling down into the audio formats and adjusting the max channels to 8 (7.1). This was originally set to 2. The pics attached should show all screens. Once updated I did the restart.exe and restarted the PC for good measure. However, the windows configuration still limits me to only stereo.
I tried using either of the HDMI ports from the RX 480. Something that was unique was that my extension blocks on the first screen had "0 detailed resolutions". I didn't see that come up in other people's screenshots.

Any thoughts on what I could be doing wrong?
Thanks.
