Custom Resolution Utility (CRU)

With CRU I've edited them in "officially" so the dongle believes it supports those resolutions - that's fine.

However - because at other resolutions the dongle supports up to 120hz, if I launch something where I can't control the refresh rate manually, the dongle then resorts to 1920x1200 @ 120hz which gives me the Active and Desktop signal disparity again.

Now usually I'd just delete all other resolutions and be done with it, but I still need them at times. Is there a way to just remove those higher refresh rates from that resolution itself (if that makes sense).

I don't understand. Why would there be a disparity? You're not giving me enough information.

Any idea what could be causing this?
4 second clip:

Horizontal white line flicker on OLED, seemingly only at 360Hz, regardless of HDMI or DP cable or port, VRR on or off. I can find various results of different monitors, TV's, QDOLED, WOLED, Dell/Alienware, LG, MSI, 27", 32", etc of this issue.
No real solutions or explanations, besides lowering refresh rate which isn't much of a solution imo. Also CRU seems to do nothing on this specific display.

Which may because DSC seems to always be enabled, no CRU changes take effect. Also perhaps this is what's causing the horizontal white line flicker at 360Hz, but if it's still in effect and unproblematic at 240Hz, why? MSI says they will be releasing a firmware update soon that allows DSC to be disabled, but even with the full 48gbps 2.1 HDMI I don't think this will allow for 360Hz 1440p at 10bit, though probably 8bit... so if it were a DSC issue, ideally it would be fixed at 360Hz. Not like I can adjust timings or anything or even try a refresh rate like 320Hz since CRU is completely ignored with this display currently, so it's either 360Hz or 240Hz...

Hoping ToastyX or some people might have insight on why this is happening and what could possibly be done about it, I really can't find anything of substance, just reports of various displays on Reddit etc with never any explanation or solution discovered... I guess people just give up, run lower refresh, or return, or it magically disappears and they never say anything.
Thanks

Also the horizontal white lines that flicker are in random places, sometimes wider, sometimes go minutes without happening, I don't know how to trigger them if it's something specific.

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

Edit: never mind, that's not the solution...
It seems that simply applying any change in NVCP that restarts the driver (black screen for a second) is what somehow fixed the issue, temporarily...
Some weird behavior, where reinitializing things solves something...

I don't understand. Why would there be a disparity? You're not giving me enough information.

Basically I can force my dongle to show that it's native resolution is 1920x1200 @90hz. Because it also can technically do 4k@120hz, Windows I think adds that refresh rate to 1920x1200 at a driver level. If I select 1920x1200@120hz it shows desktop resolution at that but, active signal mode at 3840x2160@120hz.

This is mostly fine as I can just choose 1920x1200@90hz manually, however, some applications force the highest refresh rate at a selected resolution so I end up with the wrong active signal mode which buggers up colour, I can't use RGB Full, only 4:2:2 etc.

Also one other thing, when I cloned the EDID from my LG TV I edited it then flashed it to the dummy plug, but forgot to check Range limits with the "include if slot available button", will that have any effect?

so i set all the settings in CRU that i need, everything is fine. however i have one question; should i leave DDC/CI enabled or disabled in my monitor OSD? i notice a difference between on or off. could this interfere with custom EDID override settings?

Hi all!

CRT: Mitsubishi Diamond Plus 230SB

First time using CRU, trying to override the default resolution with new 1024x768 125Hz.

Tested this new resolution in NVIDIA Control Panel and it works perfectly as shown in this screenshot:

Since none of the timing presets in CRU result in these timings, I guess it's just a case of copying these timings into CRU manually as shown:

Yeah, this seems like an obvious question but I just want to make sure I'm not going to mess anything up, cheers!

Hi,
I have a setup with an Intel HD 530 card connected with DVI and an awkward LED matrix screen of 384x128px connected with HDMI.
From my experiments, an extended screen dual-monitor setup always seems to work on the LED matrix screen as a secondary monitor, when the "Active Signal Resolution" is 1920x1080@60Hz but the "Desktop Resolution" is the native resolution of 384x128.
For some time I had it running (!) by creating a Detailed Resolution of 1920x1080 and an extension block with HDMI support and a resolution of 384x128.
For some reason now, I can't repeat that success. Both (Active Signal and Desktop) are always 1920x1080, no matter what I put into the extension block. This drives me mad. Is there any obvious reason why this was once working and not any more? I've tried for hours now and will install Windows 11 anew.
This is extremely frustrating when you know that there is a woking configuration but you're just not able to recreate it.
Does Windows 11 generally interpret the Detailed Resolution as Active Signal Resolution and the resolution in the extension block as the Desktop resolution? How can I control these two resolutions separately from each other?
Would appreciate any help on this, before I consider jumping the window

There's nothing different about resolutions in the extension block. You're talking about GPU scaling. CRU only deals with active signal resolutions, but lower resolutions can be scaled to the first detailed resolution if you enable GPU scaling in Intel's control panel. The problem is Windows doesn't provide a way to set the resolution below 640x480, so assuming the driver allows 384x128, you'll need a third-party program to actually set that resolution. I don't know how you did it before because that was always the case.

That will work. The timing matches "Automatic CRT" at 1024x768 @ 85 Hz, but with 125 Hz for the refresh rate. You should try the CVT or GTF standard if you want something easier to test.
