You should really read the first post, and there's no way your monitors will accept 8K anyway.

oh i read all the posts and didn't see one that would help.... i dont care if the monitor accepts the input i just need CRU to set the resolution to 8k so how to i get it to do it ? thanks for the support so far

Unfortunately DSR is not an option for me either as my primary monitor triggers DSC no matter how low I set the resolution or Hz and Nvidia disables DSR altogether if DSC is in effect. Sadly, unlike AMD, Nvidia has to enable DSR for all connected displays with no option to activate it only for specific ones.

Is there any other option I have?

Alright I'll check this out, thanks!

Hi,
i bought a new 360Hz oled monitor Gigabyte FO27Q3.

When I checked CRU to remove 4K resolutions on HDMI connection I noticed the following:

Variable refresh rate under HDMI2.1 support shows 48-360Hz range. But
FreeSync range shows 48-240Hz only

       

Any idea why it only shows 240Hz for FreeSync? It should be also 360Hz, or am I wrong?

Thank you in advance

Probably just switching to 3840p/60Hz would have been sufficient. I don't think I had to do this previously.

I have an LG C1 and was previous connecting my 3080GPU directly to the TV. I had no issues removing 4096 resolutions or doing any other common task with CRU.

Recently I am running my PC through an Denon X3800H 40gbps AVR. Now that CRU recognizes the Denon AVR as my "display" and doesn't directly see the LG C1 EDID at all, I can not seem to do this without losing signal completely until I reset back to default.

I can't figure out what I need to do to successfully remove the 4096 resolutions. I am forced to use Display scaling now rather than GPU scaling, because my Windows Active resolution is stuck at 4096x2160 even when the Display Resolution is set to 3840x2160. This results in 3840 Display res being letterboxed like 4096 should be, and 4096 res fills the screen (obviously not correctly scaled). This is with GPU scaling/No scaling.

Display scaling/No scaling scales properly, but not GPU. It's hard to troubleshoot this because besides the additional variables in the chain, so few people have HDMI 2.1 receivers with PCs attached I can't find any info about is. I need to either force Windows 11 to set the correct Active resolution or remove 4096 as an option altogether but am coming up empty.

I can't get it to work anymore. Any solution for this? Swichting to 1080p/60Hz does not work.

Edit: I was able to make it work by switching to 4k120Hz,Nvidia color depth settings RGB full 8bit. HDR and VRR was on. TV audio passthrough set to automatic. I don't know though, kinda feels like it was luck. Jesus, tech these days.

The FreeSync data block can only define a maximum of 255 Hz. The data block is proprietary, so I don't know if there is a new way to define higher ranges. It might just be there for backward compatibility with older GPUs that don't support HDMI 2.1.

I don't think you read the first post. It tells you why the numbers turn red, and it has important information about the limitations of various interfaces. CRU can't create virtual resolutions, so even if you don't want the monitor to display the resolution, you are still limited by the port used. You probably won't be able to add 7680x4320 except at very low refresh rates that fit within the pixel clock limit for whatever port you're using.

I am currently using a pc with an AMD Athlon 3000G and iGPU , the motherboard is an Asrock X370M-HDV R4.0 Bios P4.00 , Monitor is a Samsung Syncmaster 997MB , drivers up to date, Windows 10 pro 64bits , Custom Resolution Utility is not properly working on this computer, the only detailed resolution i made that works is 1920x1080 60hz cvt , anything else either blackscreens or throws me back to 640x480 60hz , i wanted to use 1920x1200 75 or 60hz cvt but when i make it it just wont appear on windows' node list , what's the issue here?

Are you using the VGA port or an adapter? Are the range limits included or not? AMD's driver listens to the max pixel clock in the range limits. Also try rebooting instead of running restart.exe. Vega 3/5's driver can be buggy with restarts.

Thanks again! It isn't perfect and I wish I wouldn't need another program just to fix the mess that is Windows' scaling but it does the job.
