Does anyone have a good grasp of HDMI 2.0a vs 2.0b in terms of supporting (eventual) higher bit formats like 4K 4:2:2 10bit which i think requires 18gbps throughput (which hdmi 2.0a cant handle?) I use DP 1.2 to hdmi 2.0 from my PC. I'm looking at getting a 3-6 port HDMI selector switch that is either hdmi 2.0a or 2.0b and cant decide which to go with.. either way they arent that pricey, under $100 as cheap as $42. This to bypass my onkyo 1030 receiver, which doesnt support 4k at 4:4:4 or even 4:2:2 nor hdr for passthrough.. Of the hdmi switches these were my choices (there arent that many that are hdmi 2.0a or higher).. ***Smartooo 26041C Premium $89.99 4x1 HDMI 2.0b 10bit HDR, CES support with 2.0b (or just enhanced CES?) ; 18gbps and 600mhz; HEVC H.265 Can turn off autoswitch (a bonus) Huierav HDMI 2.0a 5 x 1 $49.99 (Same basic features as the 3 port below) ***Huierav 3 port $42.99 HDMI 2.0A **should be able to select a port that’s NOT active, though it does AUTO switch and cant turn off auto Lists 600mhz, so should be 18gbs (but contradicts HDMI 2.0a, i thought 600mhz was only hdmi 2.0b?) Any ideas on this.. i'm leaning towards the Smartooo, simply because its hdmi 2.0b, but maybe the 3 or 5 port Huierav is just as good and capable of even 4:2:2 10bit? Thoughts?
