Hi I have a 4k Comcast cable box and Netflix and Amazon prime and so on...
I have a Samsung qn75q9fna.
The video can be Super grainy with hdr mode on. Also under gamma should I be using bt.1886 or st.2084 or hlg?
I have tried streaming the same 4k HDR show Jessica Jones on Netflix using my Comcast 4k cable box and using the smart TV and I have the same issue with HDR on. Any suggestions would be great at this point. I have even unplugged the power to the one connect box and plugged it back in. I know that resets some stuff. Help! Super grainy picture! My 4 or 5 year old 60 inch Samsung 1080p tv picture looks so much better.
