I have the Q900.   I was able to get 4k120hz working with my Series X when i plug the 2.1hdmi cable that came with the console into port 4. But I had to turn off Freesync for the picture to not go blank. Is this the correct way to do it? Is there an update that will enable freesync with 4k120hz?   MORE IMPORTANTLY: why am I not given an option to do 8k60hz or 8k30hz when the TV and the console are both 8k??   Thanks in advance! ...
