Sometimes Intel driver starts to output 4:2:0 and I have no controls to change it, need to find a way to disable all modes except YCbCr4:4:4 , thank you beforehand. Need 4:4:4 at least in 3840×2160@23.9 mode, I don't highly care about the other modes. Also no hdr is necessary.
My DP-HDMI adapter is ugreen 4k@60, don't know, it's warm when it's working, so probably it means it's active, I suppose.

The problem is you're using a DisplayPort to HDMI adapter, and Intel doesn't seem to provide a way to change the color format with DisplayPort. There is no way to disable RGB, so there's no way to force the driver to use YCbCr 4:4:4 if the control panel doesn't provide a way. I can try adding YCbCr 4:4:4 as if it were DisplayPort and remove YCbCr 4:2:0/4:2:2, HDR, and anything higher than 8 bpc, but if the option to set YCbCr still isn't available, then it will be RGB 4:4:4.

Thank you! Is it correct way to install, if i import it, then export as exe, then install that exe ?

Also, I know it's offtopic here, but as i have no luck on windows with intel driver to set ycbcr on DP, will another os'es able to do it, like ubuntu or etc?

You shouldn't need the exe method with any recent Intel GPU. Just import the file and restart. In Linux, YCbCr support would depend on the driver.

HDMI 2.0 has enough bandwidth for 3840x2160 @ 120 Hz with YCbCr 4:2:0. Even though this wasn't officially specified until HDMI 2.1, I don't see anything in the HDMI 2.0 specification that forbids this, so I would say this is an AMD driver bug or an intentional limitation for some reason. If you export a file and post it here, I can check if YCbCr 4:2:0 support is defined correctly.

I've attached an export, thanks. I am able to use 4:2:0, but it doesn't affect what resolution/refresh rate I can output at. And when setting a custom resolution the calculated pixel clock and 600MHz limit aren't affected (I'm not sure which would change?).

Greetings to all! Thank you for this application, it helped me set up a custom resolution and increase the frequency of the monitor, but there is such a question, is it possible to overclock it even more and how? I have a Lenovo Ideapad Gaming 3 laptop with a Full HD 1920x1080 monitor, the refresh rate is 120, there are 2 video cards, built-in AMD Ryzen 5 4600H, and a discrete 1650Ti. The monitor was able to overclock to 144 Hertz using your application, but I wonder if it can be overclocked to 165 or higher. I'm playing CS 2 with a resolution of 1280 by 1080 and I can go to any tricks to overclock the monitor to even higher frequencies.

Radeon Software states Custom resolutions are not compatible with clone mode, Eyefinity, and FrameLock/GenLock configurations.

Knowing this, is it possible to add a custom resolution to each monitor, and somehow make the radeon software make an eyefinity resolution, from that custom resolution?

These are the standard resolutions for the monitors, and the only resolution allowed thus is 5760x1080.
I would like a different resolution with same aspect ratio of 48:9
like 4800 x 900 for example
Reason is, my gpu struggles to make acceptable framerates in some games.
ToastyX maybe you have some idea?

Hello ToastyX whenever I create a custom resolution there is a mirrored line down the middle of my monitor, can you help me?
the resolution im trying to get is 1720x1080 Im using the Odyssey G40B 240 hz monitor connected to nvidia rtx 3060 ti, also Im using it connected via DVI port I think, im not sure, all I know is that it is not hdmi

Just signed up to say that I've used CRU here and there as I've wanted to tinker or explore limits of an old laptop monitor and so forth. Two questions I suppose:

1) Is the workflow essentially use CRU to figure out your display's limits and then use the EDID utility to write those changes to the display? (The goal here is to use two old monitors with Linux but getting all the settings correctly set up is kind of a nightmare there. Your software is just amazing for tinkerers and is, in itself almost always a reason to have a Windows partition when wanting to tackle the display.

2) Would you consider submitting it to winget? I also just started exploring package management on Window? (even if like... living within the winget folders and not being truly "installed" anywhere? Automated updates... even if its living in the downloads folder... would be oh-so-lovely: https://github.com/microsoft/winget-pkgs)

(I just found with 1.4 or whatever their latest package management standards are that Windows package management is finally viable.) So I decided to use it to manage a bunch of third party applications and keep them up to date. Thinking maybe having a powershell scripts to automate times for an "auto update command" like winget upgrade --all --include-unknown --accept-package-agreements. Its nice to get a Linux-like package manager experience for finding, using, upgrading third-party applications via command-line, but there are still some installers that pop up here and there. Usually all automated though.

In the CTA-861 extension block, delete the 4:2:0 capability map data block, and then add a TV resolutions data block with 4:2:0 resolutions enabled, and try adding 3840x2160 @ 120 Hz in there.

You didn't say what happens if you try to go higher.
