UE49KU6400 HDMI UHD

[cureboi]

I am running my UHD blu ray player into the HDMI2 port with the HDMI3 ARC going back through the AV amp & have my STB going into the amp (not HDMI1 on the TV).

I am trying to set HDMI UHD to on for all 3 HDMI ports & am only able to set for HDMI1.

The other 2 are greyed out despit having active connections to them.

How can I set to on for all 3 ports?

Hi, only a year and a couple of months later lol.

I stumbled across your question as I had the same one after my PS4 told me HDR wasn't working through my Denon receiver!

You probably know by now, but thought I'd reply, as no one else has!

HDMI 1 is the only HDR HDMI port, the other 2 are only UHD...as far as I've found out.

I've only had the telly 3 years to figure out ive been using the wrong port haha.
