Custom Resolution Utility (CRU)

[KoKlusz]

Hi, I'm apologize if this was discussed before, but googling gave me nothing.

My question is: is it possible to use custom resolution with Nvidia sending 4:2:2 10/12bit to the 4K display via HDMI 2.0? No matter what settings in CRU I'm using TV (UEKS7000) always rejects the signal.

I make custom resolution in CRU (I used auto LCD Standard timing before and it worked fine) but it doesn't work anymore. I even did manual and copied timings (which were the same) and whenever I switch to the resolution, my monitor goes out of range. When I do same timings and resolution through NVIDIA control panel it works fine.

What monitor? With the NVIDIA control panel, does the resolution still work if you change the standard from "Automatic" to "Manual" with the same timing parameters?

Yes if I change to manual and keep the timings it still let's me use the resolution.

That's strange. The same timing parameters should work with CRU. Are you using DVI? Any adapters? Export a file and post it here so I can see if there's anything strange.

Custom resolutions don't have a way to specify a color format. YCbCr formats are normally limited to TV resolutions. If you're trying to add lower resolutions, try GPU scaling.

No adapters Yes I'm using dvi I even tried dual link, and export what file?

Hello, I used this program and played around with it not knowing what I was doing to be honest and I turned off my computer last night and then turned it in this morning and it would boot up but when it got to the login screen it would just be black and then my monitor would say check video cable. I’m not sure what to do and hope you can help. Thank you

Boot into safe mode. Then run reset-all.exe and reboot.

Export a file from CRU, any format.

How do I get to safe mode?

Yes I do DP -> VGA, some generic cheapo one, pushes somewhere close to 240mhz, waiting for better one with way higher clocks to arrive.
