A:AnswerYes, try new high speed cables.. You will need a ultra high speed hdmi cable with at least 18 Gbps(maximum bandwidth) or greater for your 4k bluray player. If you have an TV with eArc with hdmi 2.1, connection, there now appearing ultra high speed hdmi cables with 48 GBPs for Dolby vision and Dolby Atmos for 8k Tvs. For at least, 4k, try audioQuest- pearl or cinnamon ultra high speed cables.
A:AnswerYes, if the Xbox or ps3 has hdmi out, the cable will work. Make sure the cable is long enough to reach the tv or if you are using a sound bar from where your game console is sitting.
A:AnswerYes, it should, works with any system that has the arc hdmi input. It'll blow your mind and you'll think someone is breaking into your house with the amazing sounds,lol!
A:AnswerHi. If it’s a fire TV edition you shouldn’t even need an HDMI to make it work. It should just be built in to the TV and have a button on the remote. Like a Roku TV. Otherwise, if it’s a stand alone unit like an Apple TV box, it would have to go from the fire unit to the HDMI in. But I think you just need to hit the fire or amazon button on the remote to pull it up. Hope this helps.
