just got a 4k UHD Samsung ku6500 tv. didn't realize only hdmi 1 port is enabled for hdr. I have a ps4 pro which would take advantage of this and I have directv. which one should be plugged into this port vervus hdmi port 2 and 3 which do not have hdr capabilities. Ive tried to do my research and cannot come to a conclusion of does any content take advantage of hdr, in which case I would keep directv in port 1, or does it have to be made specifically to take advantage of the technology, in which case I would put ps4 pro in port 1. Any guidance would be very much appreciated.
