My screen LG 27UDP68 supports 4:2:0 color.

It doesnt work with the default extension block, so maybe with the second option.
When I add HDMI support there is only 3840 2160 30hz option so I tried to add the HDMI 2.0 support.
Everything I tried there didnt work.
Add HDMI support, not HDMI 2.0, and you need to have at least one detailed resolution for the native resolution. Are you sure the GPU is dedicated and not switchable? If it's dedicated, CRU should have been able to read the extension block. If it's switchable, Intel's GPU takes over the inputs, and I don't know if Intel supports 4:2:0 resolutions.

A bit late Big Grin , still it doesnt work
The computer is Lenovo y50-70 - intel graphics 4600hd (i7 4720HQ) with Geforce 960m
I did a reset to the CRU application and tried again like you said
Here in the picture you can see I added HDMI support and 4:2:0 resolution with the resolution I want 4K60HZ.

Thanks for your help

First, you should check if Intel's driver supports EDID overrides for your GPU by adding a lower resolution. If that doesn't work, then nothing you do in CRU will have any effect. Second, I'm not sure if Intel's driver allows adding 4:2:0 resolutions using EDID overrides. Make sure to delete the first 3840x2160 @ 60 Hz detailed resolution because that's for 4:4:4 resolutions, so you can't use that with HDMI 1.4. You might have to add 3840x2160 @ 30 Hz as an HDMI resolution in the HDMI support data block as well.

When I add a new resolution I can choose it on the intel's driver so I think the driver supports EDID overrides.
I also deleted the 4k 60hz from the detailed resolution, and added a 3840x2160 30hz in the HDMI support
Still cant choose 3860x2160 60hz in the graphic's driver Sad
