I thank you for this feedback. It would be nice that new drivers would have it to support 4k at 60hz.
I hope so, and i wondering is there a way to make request for this? or somehow give that information to driver developers team?
I wondering in recent version of drivers are we able to set 4:2:2 Y'CbCr colors? Because this is the whole trick to reach 4k 60hz via 1.4 hdmi, maybe we don't need a new version of drivers?
