Custom Resolution Utility (CRU)

[Man]

Does CRU works on the new RX7600? Or has AMD completed fused-off third-party EDID access with RDNA3?

Can anyone confirm it?

Thanks!

EDID has been broken for all AMD cards since the 22.12.1 driver that was released alongside the 7900 cards. Use the bug reporter tool to report EDID overrides not working and hopefully it'll get fixed at some point. I've been filing bugs for every release.

The thing is, I'm using an old CRT 1680x1050 60Hz monitor connected to a GTX 1650 via a VGA to HDMI adapter, so when I first install Windows, the system thinks my native resolution is 800x600, and after installing the drivers - 1024x768. On Windows 10 I just added my native resolution to the CRU and everything worked just fine, but Windows 11 just ignores any changes to the CRU as well as the SRE. The only thing that works (kinda) is the NVIDIA control panel, but the colors start to get distorted. For example, some color wheel looks fine, but the gray to white gradient looks like a bunch of big gray bars. And by the way, it shows me that i'm using "DVI-PC Display". What can I do to make everything work the same as in Windows 10? Once again: CRU doesn't work, and neither does SRE.

What does CRU show? If you see "Generic Non-PnP Monitor" with no resolutions defined, then the monitor doesn't have a valid EDID. Windows 11 doesn't seem to support EDID overrides for monitors without a valid EDID for some reason. You would need an HDMI to VGA adapter that provides its own EDID, or you can add an HDMI EDID emulator like this one: https://www.amazon.com/dp/B08RCMFLMK/?tag=mtests-20#ad

So far I haven't heard any reports of EDID overrides working with RX 7000-series GPUs.

The problem only affects RX 7000-series GPUs.

Laptops don't have scalers and can't display non-native resolutions without GPU scaling, but Intel doesn't seem to provide a way to add custom GPU-scaled resolutions with laptops.

That is accurate. Still no support for custom EDID's on my 7900XT.

Hi. I've got a spare 65" 4k tv (3840 x 2160 px) that is slightly damaged in the bottom part of the screen only, and rather than dispose of it or sell it for peanuts, I want to use it as a desk monitor, so that only the top 1600 px or so is used by the operating system and the bottom pixels are unused (as screen damaged there). I have it sitting on a stand behind my desk and is already lowered so that only the top part of the telly is above desk height. I would like the windows taskbar to be at desk height which is 1600px from the top of the screen.
I found out about ToastyX on Google, but I have no advanced knowledge of graphics cards and the inner working of monitors etc., so I'm a bit nervous of bricking my monitor. Can ToastyX achieve what I need, and if so, how could I blank off the bottom x number of pixel rows off my screen? Any help would be much appreciated (via Patreon also).

Hello.

I recently discovered CRU and have been using it to create custom resolutions for myself. They've always worked within the normal range for me. I basically use the program to create native 60hz resolutions and then create a custom 77hz resolution through AMD Radeon Software (it's safer to do it that way in my head). I created many of them (1440x1080, 1600x1024, 1280x1080), all with 77hz (maximum my monitor supports, above that it has no video response). But recently I've preferred 1920x1080 since my game (Valorant) doesn't have in-game differences between 4:3 and 16:9 and I ended up finding it a problem. At 1920x1080 the maximum I can put is 73hz. I was curious and went to try to understand why. I read the whole document and understood that the reason for this is probably the "max pixel clock" which in my case is 170MHz (as in the image). But the doubt came to me, shouldn't my limit be 300MHz? I have an RX 570 (which has an HDMI 2.0b output) and an HDMI 2.0 cable as well. Shouldn't it have a higher pixel clock number? Or does this parameter depend on the monitor?
