They obviously can be set from custom resolutions in my control panel but then then gives me desktop resolution and active resolution disparity. 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.

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.

DDC/CI is for controlling the monitor's settings such using a program, like you would through the monitor's menus. It doesn't affect anything related to the EDID.

Why would that affect custom resolutions in the control panel? With CRU, you can just add 1920x1200 @ 120 Hz to make it not scale. CRU automatically includes the range limits if needed, so it shouldn't matter.

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

You posted this already. I said use GPU scaling. Why not just use SRE?

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.

That looks like a signal quality problem, but if it's not the cable, then either it's an internal problem with the monitor, a bug in the monitor's firmware, or a bug in the GPU's driver with regard to DSC. If CRU doesn't have any effect, that's a GPU driver bug.
