Custom Resolution Utility (CRU)

However it always causes extreme ghosting like green and black ghosting in game. Is there anyway to solve this or should I just stick to the in game 4:3 or 3:2 setting. I would prefer 17:12 but the game doesnt have an option. Im also on an AMD Radeon Card (7900 XTX). Thank you

I don't see how changing the aspect ratio would cause ghosting unless the monitor can't handle the resolution correctly, in which case you can use GPU scaling, or add the resolution you want with SRE instead: https://www.monitortests.com/forum/Threa...Editor-SRE

MSI MAG 321UPX QD-OLED (same as 312URX) , trying to set 230 max fps, no matter what i fix in the CRU, the system-display and nvidia panel wont see it, looks like it is saving in the CUR after restart but windows just won't pick up it.

What GPU do you have?

The issue is described in the first post:

NVIDIA and DSC - ToastyX Wrote:NVIDIA's driver currently ignores EDID overrides when Display Stream Compression (DSC) is active and the maximum resolution @ refresh rate combination exceeds the GPU's single-head limit (around 1350 MHz pixel clock for RTX 3000/4000-series GPUs). 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

if that is the case, what driver version should i use to get cru working? i can duu current driver and use anything, vrr flicker is killibg me , its my only hope. if not, i will have to use 180 refresh rate

There is no driver version I know of that works. The only workaround is to disable using multiple heads internally, but then you'll be limited to 1350 MHz pixel clock, which is only enough for about 150 Hz. 5000-series GPUs don't have this issue.

alright, thx for the replay, at least i know buying 5080 will fix my problem

Please, somebody help, im tired of gooling for 3 days

I need to add 2 10Bit resolutions to my dongle [I do CRU, save file and then flash it to dongle, it works]
I can add resolutions fine, but they always 8bit
Please for the love of god, help me, how to add 10Bit resolutions?

I copied all HDMI 2.1 and HDR settings from my main display S95B oled, DIDN'T help, I can enable HDR on the dongle but only 8Bit + Dithering


These are the 2 resolution i need to add:

2816x1940 /10bit
1408x970 / 10bit

Thanks in advance

Is 30-bit deep color and YCbCr 4:4:4 deep color enabled in the HDMI data block? Are you able to get 10 bpc with TV resolutions such as 1920x1080 or 1280x720? Does the dongle support HDMI 2.0? It won't be HDMI 2.1. If it's HDMI 1.4, bandwidth will be limited. What GPU do you have?
