240 MHz is the limit for 2-lane eDP, and that's with 6 bpc color. The limit for 8 bpc color is 180 MHz. This is common with laptops. The patcher does nothing for DisplayPort limits. DisplayPort is packet-based and runs at fixed clock speeds.

i thought Extension blocks was what you where asking about

I meant in the extension block list, not the type. The .bin files are valid, but NVIDIA's driver has a bug that causes it to ignore overrides that don't have at least 2 bytes left for data blocks. You can delete the HDMI data block because it's not needed with DisplayPort, and you don't really need the TV resolutions either.

Thanks
will try it when i get up

My graphic card is a 2080 ti.

How do I force 4k 120hz and 4:2:0 in cru? When I add the resolution like normal there is no way of changing it to 4:2:0 and the screen goes black because the bandwidth is to high without 4:2:0 enabled.
In the CEA-861 extension block, add a TV resolutions data block with "4:2:0 resolutions" checked, but I don't know if the driver supports 4K @ 120 Hz that way. I don't know how he got it working with NVIDIA's custom resolution because that normally doesn't allow selecting YCbCr 4:2:0.

Thanks for helping me! Smile

I removed "4:2:0 cabability map" from Data block. Then I added a new data block "tv resolutions" and then I added 3840x2160 with 4:2:0 enabled. I then restarted and tested the resolution and this time I didn´t get black screen instead it shows 3840x2160 and 120hz when I click info screen on the remote. The problem is the screen artifacting like if you choose a resloution that the HDMI 2.0 can´t handle. Partly green screen with artifacting horizontal lines. So it seems it doesn´t work. My cable works with HDR and 4k at 60hz so the cable should be able to output the bandwidth of 3840x2160, 120hz and 4:2:0.
I just don´t understand how this person got it working: https://lebgeeks.com/forums/viewtopic.php?id=18305

Do you think there is a solution for this or the x930e probably isn´t supporting 3840x2160, 120hz and 4:2:0?

thanks it worked i deleted the hdr static metadata
and its fine now

I actually tried doing that with my vega 64 but it still showed hdr

that fixed a long running problem of dx12 games auto turning on hdr
when i dont want it as it looks worse than my settings

Hello!
I have MSI RX5700 Gaming X and MSI Optix G241.

I want to set custom resolution because when I have 144Hz my GPU Vram working hard on +1700MHz. I tried set this in drivers but I can't save customs settings. When I try set profile with 143 or 142Mhz my display turns off for 20 seconds, after this time appears "HDMI no signal", display turns on and still working on 144Mhz. I tried make a new profile in CRU. Custom profile from CRU also didn't work. I can set a new profile but vram still working on max value. What I should do? Do you think display port cable can resolve a problem?

You need to keep the pixel clock under 340 MHz for HDMI 1.4. DisplayPort will allow up to 360 MHz.

Hi,

Need some help to configure CRU.
My setup: a laptop (CPU is i5-1035G4) running Win10 -> HDMI to DisplayPort adapter -> Apple LED Cinema 27 Monitor (A1316). The computer detects the monitor, but could not make it active, monitor remains black screen.
To verify that the monitor is okay: with the same setup, except booting into Linux. the nonitor works just fine.
To verify that the "HDMI to Display Adapter" works in Win 10, I swapped out only Apple LED Cinema 27 monitor with Dell 27 monitor, everything works fine too.
What shall I change in CRU to make original setup working?

Thanks in advance!

I found problem. When I connect main monitor (MSI G241) via DisplayPort and set 142Hz GPU work correctly but when I connect second monitor (LG E2251) via HDMI or adapter DP>HDMI vram again jumps to +1700MHz. Have you guys an idea what to do after connecting the second monitor so that the value does not increase?

Both monitors must run at the same resolution and refresh rate with the same exact timing parameters to synchronize the monitors. The memory clock changes during the blanking period to avoid screen corruption. If the two monitors aren't synchronized, it can't change the memory clock without corrupting one of the screens.
