You could run down to Walmart they have some good HDMI cables You should only need two one from your 4K play to your AVR and one from your AVR to your 4K HDTV that should do it. Have you tried another movie just to see? or one of the apps in your player?\n\nI already ordered 2 certified cables from Monoprice. They were under $20 for a 6 foot pair. It does play a Transformer movie but it’s not 4K hdr Dolby vision\/atmos. I’m hoping it’s just the old cables or some setting I missed on the blu Ray player.
