Custom Resolution Utility (CRU)

[groovesalad89]

Hello ToastyX
I've bought a couple of mighty CRT displays but can't make detailed resolutions work properly.
I'm using Win10 and GTX1060.
1) I go to CRU;
2) Choose display;
3) Create detailed resolution;
4) Click "OK" and run "restart64";
5) Restart PC
At the end of this I see only 1024x768 120Hz, that I've added. But there's no others like 1280x1024 115Hz or 1440x1080 100Hz. I can't see them in properties of my video adapter (((
What am I doing wrong?
Help please! Thanx a lot!

How are you connecting the monitors? GTX 1060 doesn't support VGA.

DisplayPort - VGA cable

That would be an active adapter, which might have its own limitations. You're probably exceeding a pixel clock limit. You might have better luck with an HDMI-VGA adapter instead.

Fixed in today with nVidia Control Panel using CVT sync standart. Works perfectly with my cable. 1280x1024 115Hz, 1440x1080 100Hz. Display is HP P1130 if you interested.
Thanx anyway! All the best!

If you click the "Edit..." button at the top, what does it report as the max pixel clock? I think the driver might be limiting EDID resolutions to that. The NVIDIA control panel uses a different driver-specific method.

It says "Max pixel clock: 300 MHz"

That's strange. Those resolutions should fit within 300 MHz pixel clock, and if you're able to add those resolutions with the NVIDIA control panel, then it's not an adapter limitation. The only thing I can think of that would stop refresh rates from appearing would be if GPU scaling is enabled in the NVIDIA control panel, which you don't want with a CRT monitor. The only other issue that comes to mind is NVIDIA won't read more than 8 standard resolutions, but you said you used detailed resolutions.

Yep. I turned off GPU scaling. Anyway. All works and I'm happy with results I have

I registered only to say thanks. I successfully forced my monitor with 4-6 check boxes in HDMI edit, to go from 8bpc to 10/12bpc. I cannot confirm if this is placebo effect due to my mind and eyes seeing 12bpc, but I know that colors popped up!

The same happened with my Xbox One X, automatically gives 8bpc (perhaps idiotic monitor EDID) but custom gave me 10/12bpc. Thank you for this tool. I couldn't find a way to do the same with Windows 10 OS. AMD radeon settings were blind.
