Hello,
I’m running Fedora 25 on Lenovo T460p with Intel HD Graphics 530 in processor and NVIDIA GeForce® 940MX. When I use CAC-1170 I’m able to get 3840×2160 at 30 HZ and even at 60 HZ but definitely not with 4:4:4 color sampling. However when I use Lenovo reduction I’m able to get 3840×2160 @30 HZ with 4:4:4 sampling.
Any idea why CAC-1170 won’t do 4:4:4 even @30 HZ?
Thanks!
