Custom Resolution Utility (CRU)

[Maxfreshwes]

Hi All,

Hoping someone can provide me with a bit of insight on an issue i've been having.

Running

Radeon 5700xt through a HDMI 2.0 Cable to a Denon AVR (2300w) and a Vizio 70" 4k TV (Compatible with 4k@60hz)

My reason for running CRU is to enable 3440x1440 to stream to my ultrawide monitor in another room (using Parsec or Steam IHS)

After a bit of trial and error, i was able to add custom resolutions using CRU and stream 3440x1440 while running parsec.

When i added the custom resolutions, running any resoloution 1920x1080, 3840x2160 would work fine @ 30HZ, but as soon as something would attempt to run at 60hz, or i would switch to 60hz in display settings, the screen would go blank, and resolution not supported would display on the TV.

if i delete my custom resolution, everything works fine @ 60hz.

any ideas what i'm doing wrong.

thanks

Apologies if this has been asked before, but is there a way to enable 10 bpc colour dept in Nvidia Control Panel when using a custom refresh rate?

I've got a Dell S3220DGF, which has 60Hz, 120Hz & 165Hz modes over DisplayPort by default.

I'm trying to create a 144Hz setting with CRU, which works, but Nvidia Control Panel always detects it as a custom resolution (even when modifying the default 120Hz mode) and forces the monitor into 8 bpc. I can select 10 bpc from the colour depth drop down, but as soon as I hit apply it reverts back to 8 bpc. Windows Display Information also confirms it's still in 8-bit mode.

Not sure if I've got something set wrong in CRU, or is there a way to force Nvidia Control Panel to see it as a native refresh rate instead of a custom one.

GPU: GTX 1080 Ti
Latest drivers installed.

That's weird because only NVIDIA custom resolutions are supposed to be listed as custom. CRU resolutions should appear under "PC" unless they changed something recently. Try an older driver like 446.14.

Show me what you're doing. Export a before and after file.

If I edit the default 60Hz resolution in CRU to 90Hz, it shows up in NVCP as a 'PC' resolution. Changing it to 144Hz, or creating a new 144Hz entry always puts it under "Custom resolution".

Hello! I had trouble when doing export/import in app - was doing to figure out how to override edid on intel with build-in display. So I'm trying set correct display size (width, height) as my display hasn't, to get proper interaction in multimonitor setup - can You please explain or in any other way show how to do it (mean override edid for intel gpu)?

I don't know what you're trying to do. What is wrong with the display size? What is wrong with the multi-monitor setup? Built-in displays usually don't support non-native resolutions, so other resolutions won't display correctly anyway without GPU scaling, which would only work for lower resolutions.

Sorry for wasting Your time - I had wrong use of edid_override in windows. I've figured out how CRU manages my custom resolution and now I'm able to write my changes. Thank You for attention and great software!

There's no way you're going to get 2560x1440 @ 100 Hz over HDMI with the HD 5450. It doesn't have HDMI 2.0. What settings do you want to import? You can export the settings to a file and import the file.
