Your TV ports are all HDMI 2.0 based, getting a cable rated for 2.1 isn't going to change things. Is it my cables or is it just the way it should work. I see belkin have released an 8K cable which actually says 2.1 in spec, the 4K vision cables does notīut isn’t 2.1 48gbs vision ? What I read online is even though belkin don’t say it on there site others say it is, maybe just a sales ploy to sell the 8K one at twice the,price. Is it possible to do this or is the MKV file just not right to transmit via arc, just perplexes me how Netflix works fine do they do something special ? Same with apple that works fine from apple store movies I’ve played with all settings in Plex to no availīoth sound bars are 2.1 compliment as well as TVs

If I play Netflix I get vision and Atmos fineīut if I stream a 4K Dolby Atmos film from Plex all I get is Dolby digital 48kz Dolby surround LG B7 connected to Sony HT5000 Atmos sound barīoth are connected via the belkin 48gbs vision cable which I believe are 2.1 compliment

Ok so I scoured the net looking for the answer but have yet to find it
