But make sure you have the correct 4K HDMI Cable and If your 4K TV supports HDR make sure that the 4K HDMI supports HDR as there are many out

I had a hdmi cable, very convenient and the price was right $124.95.

I have the player plugged directly to the TV and an optical digital cable returning sound to the receiver so that I can enjoy the better video quality

And yes I do have the right cable - my husband is a wizard at installation.

The remote doesn't seem to work as you'd expect either.
