Problem is that when I change something with CRU and then when I either turn monitor off and then on (manually or through windows) or enter sleep mode and then resume working, screen became fading, like there some dark filter on screen. It return to normal if I change resolution or refresh rate or turn off/on gpu scaling in driver settings. This problem occur with all Adrenalin 2020 Edition drivers, but previous 2019 Edition drivers works fine.
As I wrote before, it didn't matter what I change via CRU, problem occur only when I change something. But I'll write what I ussally change, just in case. I delete all resolution that above monitors's own (2560x1080) and I change Freesync range from 40-75 to 25-75.
My monitor is LG UltraWide 29WK600-W connected via HDMI, GPU is AMD Radeon RX 580, CPU is AMD Ryzen 7 3700X, Motherboard is MSI X570-A PRO.
P.S. I think I made a lot of mistakes in the text, but English isn't my native language so I hope you'll forgive me for this.
Sounds like an HDR bug in the driver. If you don't need HDR, try turning off HDR in the Windows display settings. If that doesn't help, try deleting any HDR metadata blocks in the extension block.
HDR already turned off in Windows display settings and I just tried to delete HDR metadata block and it didn't help.
As far as I noticed this problem occur when I changed something, no matter what exactly so it happend when there is override and since it's occur only with new drivers, I think the source of problem is driver, but I tried different driver settings and none of them solve this problem.

Hi,

Was there ever a solution found to this problem? Tried searching this thread, but didnt find any further discussion.

I have the same problem and haven't been able to use CRU with AMD 2020 drivers. There is a thread about this on AMD forums: https://community.amd.com/thread/246376

There is a proposed solution of enabling 10bit pixel format under Graphics settings. While enabling it removes the dimming problem, it effectively brokes Freesync functionality as 3D apps become totally unusable flickery and stuttery mess. Plus lots of screen blackouts during launching and exiting 3D applications.

Im using Vega GPU and Samsung CF791 display. Anything that could be tried?

Yes, delete the default extension block with CRU. Why do you have three extension blocks? Why did you delete the detailed resolutions? Where is the HDMI data block that I told you to add? You need one extension block with HDMI support and 4:2:0 resolutions. You need one detailed resolution to define the native resolution.

Ok I did what you said,and im missing something because I have lose all 4k resolutions,only 1080p left to choice in windows.Also I can add 4k res by hdmi support at picture 4 but only 30hz..

Hey ToastyX! I'm hoping you can help.

I have an Acer ED273UR 1440/144Hz display connected to my gaming PC (RX 5700 XT) with DP, 1440, Freesync, all good. Nintendo Switch on the HDMI input, also good (though 1080p obv).

On the DVI input, I have a Thinkpad dock connected to an HDMI KVM, then to the monitor with an HDMI-DVI cable. The dock is shared between a T450s (i5-5300U) and X270 (i5-6300U). When I first connected this, it was finicky, but it worked at 1440/60 (albeit with very minor artifacts). Something happened yesterday and now it refuses to recognize 2560x1440 as an available resolution.

I tried creating a custom resolution in the Intel control panel but I get "The custom resolution exceeds the bandwidth capacity."

I downloaded CRU and added 1440/60 to the Detailed Resolutions, but it's still not available. Not sure if the Intel driver links on the first post of this thread are accurate, but they reference v15 and I'm on v20 and v26. The Intel links also say the drivers are only for Win 7 and 8.1, but I'm on 10.

If I connect the HDMI cable to the Thinkpad dock, it recognizes 1440 fine. I'm hoping there's some way I can capture this config and then force it even when it's unavailable.

You need an HDMI support data block in the first extension block. Intel changed the links at some point. I don't know which drivers work with EDID overrides. The way they handle drivers is confusing. They have a bunch of different driver versions and multiple branches for different GPUs instead of a single unified driver like AMD and NVIDIA. Newer drivers should work, but some people had issues with DCH drivers.

Try changing the first detailed resolution to 30 Hz. If 60 Hz still isn't available, then the driver doesn't support YCbCr 4:2:0.

What exactly did you change?

It has to be a driver bug related to HDR. Maybe try deleting the HDR data blocks from the extension block and remove all higher than 8 bpc color formats in the HDMI and HDMI 2.0 data blocks, if this is HDMI.

Normally laptops with Intel GPUs only support up to 300.99 MHz pixel clock with HDMI, which isn't enough for 1080p @ 144 Hz, but then 3840x2160 shouldn't have worked unless it was 30 Hz or YCbCr 4:2:0, so I don't know.

Ok, thankx for teaching me some of your knowledge, and just one other thing, do you know something about the screen sometimes blacks out for 2-3 seconds than goes back to normal. It's really random i dont know how to reproduce this, and in the screen doesn't show any "connection loss" message, it's like when you change the resolution.

Thank you for answer,seems that drivers doesnt support 420 at 60hz but 30hz does as you can see on picture 3,Im not able to add 3840x2160 60hz no matter what..Just dont know why 2k60p can be added by same way.Confused...
