So, even using your software or using Nvidia Custom Resolution, I get a black screen because they try to create a PC resolution, not an HD compilant resolution.

There's no functional difference between PC and HD resolutions. NVIDIA just decided to list TV resolutions separately. There's no way to add 2560x1440 @ 60 Hz as an HD resolution because it's not a standard TV resolution.

HDMI 1.4 can already handle 2560x1440 @ 60 Hz. You shouldn't have to do anything special if the TV supported it. CRU doesn't support 4:2:0 resolutions yet, but it's possible to import them.

Try importing this using CRU: https://www.monitortests.com/2160p420.dat

That includes 3840x2160 @ 60 Hz as a 4:2:0 resolution in the "Extended (14)" data block along with HDMI audio support. I don't know if NVIDIA will add 4:2:0 resolutions with an override, but it's worth a try.
