I have been able to use the default settings to add the resolution at the desired refresh, however there is a thin bezel around the display which shows GPU artifacting of stuff rendered at the edge of frame. What settings do I need to change to effectively "overscan" the image?

You can't overscan with a custom resolution. Use GPU scaling if the monitor can't display the resolution correctly.

Hmm, I am already using GPU scaling. I believe what's happening is that because it's an OLED, there's a bezel around the image where the monitor will offset the image a pixel or two every 10 minutes or so to prevent burn in. Just in official resolutions, this is blacked out/overlaid with a border - while in the custom resolution, it's black but still renders what's at the edge of the screen.

Using the standard Nvidia custom resolution works and prevents this artifcating - however Nvidia's implementation doesn't allow for HDR in these custom resolutions (which is how I was directed to CRU). Seem to be stuck between a rock and a hard place! Guess I may need to just eat the performance loss and stick to the native 3440x1440 resolution :/

This is what I have:

Show me the whole EDID. Export a file and post it here. What GPU are you using? Have you asked Sonos support?

I have a GTX 1660 ti.

EDID Export:

  EDID.bin (Size: 256 bytes / Downloads: 255)

I haven't reached out to Sonos support since other devices are getting 5.1 without any problems.

On 6700XT I was able to force 4.2.0 Chroma to get my 4K TV 60HZ do a 120 HZ with 2.0 HDMI. Not so much with 7900XT. Am I to assume that is a driver issue?

Report EDID overrides not working with the 7900XT to AMD using their bug reporting tool: https://www.amd.com/en/support/kb/faq/amdbrt

Thank you sir. So AMD has to update their driver for it to work, correct?

My motherboard (ASRock x570 ITX TB3) has a TitanRidge TB3 controller with DP1.4, so there's enough bandwidth to support 6k...but, as reported by others ( https://forums.macrumors.com/threads/app...t-29114824 ), Windows doesn't seem to expose a 6k resolution when using TB3. On the other hand, I'm able to support 5k with 10 bits (or even 12, despite the monitor only being 10 bit), which is more bandwidth than 6k8bit -- so I'm convinced this is an EDID problem.

Can you describe how everything is connected? From what I've read, you need two DisplayPort cables from the NVIDIA GPU to the Titan Ridge controller, but I only see one DisplayPort input on the motherboard. The 6K resolutions don't fit within the max pixel clock for DisplayPort 1.3/1.4 HBR3 (1080 MHz pixel clock at 8 bpc), so either it requires two streams or display stream compression (DSC). Maybe the Titan Ridge controller is preventing DSC from working. Why not connect the monitor directly to the video card using the Moshi USB-C to DisplayPort cable?

I don't think anything is wrong with the EDID. The reason CRU doesn't list the monitor is because the reported EDID in the registry is supposed to be the first 128 bytes only, but apparently that changed with Windows 11, and your monitor is reporting 5 extension blocks, while older drivers only supported up to 3, so CRU saw too much data and failed to process the monitor. I will fix that in the next version. For now, try this: https://www.monitortests.com/CRU-EXT.zip

This post has a lot of great detail on how Apple accomplishes 6k60 using Thunderbolt 3. You don't need more than a DisplayPort 1.4 cable -- with DSC, you can run 6k60@10bit at 14.66GB/s, which leaves enough for 5GB/s USB 3.0 over Thunderbolt.

I have recently upgraded to the Pro Art X670E, where the JHL8540 Controller lets me get full 6k60@10bit over a TB3 cable using the iGPU. However, when I connect the DisplayPort passthrough from the GPU to the Motherboard, I get a black screen. After Chrome Remote Desktoping to the computer, I see it's connected at 6k60 6bpc, which I don't think the display supports. Is there a way I can set a custom resolution to force the correct settings since it looks like Intel's TB4 controller is doing odd things? Of note, I'm unable to set a custom detailed resolution at 6k -- the text is red. I think CRU doesn't account for DSC since those resolutions are possible over DisplayPort 1.4, right?

Would appreciate any help!

No, that's not correct. Read the first post for detailed resolution limitations, but there's no point in adding a custom 6k resolution anyway because the monitor already defines the correct 6k resolutions. DisplayPort only drops down to 6 bpc if there's a bandwidth limitation, so something is wrong with this setup.

I don't see anything unusual that would prevent it from working, so I have no idea. The only thing I can suggest is since the graphics driver is responsible for the HDMI audio driver, try reinstalling NVIDIA's driver after using DDU: https://www.wagnardsoft.com/display-driv...aller-DDU-

I don't understand what you're saying. How can it be black and render what's at the edge of the screen? There shouldn't be any artifacts. The monitor doesn't black out any part of the image. The panel has extra pixels for shifting. Try using Scaled Resolution Editor instead: https://www.monitortests.com/forum/Threa...Editor-SRE

Hello again ToastyX and friends
New monitor, new fun
(Well, cheap second hand monitor)


This one supports DP 1.4 in it's OSD, but seems to not give any more bandwidth than when ran at DP 1.2
Two cables tested, both claim to be DP 1.4 / 8K capable

GPU-Z shows 5.4Gb/s x4

The monitors values are very different between HDMI and DP, but i'm hitting a wall where it blanks out at even 590Mhz on DP, despite it going higher on HDMI (for a lower refresh rate)

Anyone got suggestions beyond running CVT-RB2 and hoping for the best?

Also If I enable free sync it seems to have more problems - should I be altering the Display properties to match the new overclocked refresh rate (an entire 66MHz, yay) - or leaving it alone?

Yes, something is indeed funky -- I'm pretty sure the JHL8540 is negotiating the wrong protocol, which should be HBR2+DSC, to connect to the display, so I've told Asus about the bug.

For anyone in a similar boat, everything works with the Belkin Cable + CalDigit TS4 dock. You can find my solution here. Hopefully Intel pushes out changes that make this more streamlined.
