Hi, I'm thinking of upgrading my TV and AV receiver to 4K and HDR. Currently looking at KD-49XF9005 TV and Sony STR-DN1080 Receiver. Currently I have Sky Q box, PS3 and Sony Blu-Ray and player (and TV) hooked up to my current receiver Yamaha RX-V673 through 4x 7m HDMI cables which run under my living room carpet. These cables are from 2007 and possibly 1.3 spec, so I'm assuming they will need to be upgraded for 4K and HDR. Could I use an HDMI switch in this setup? Presumably I then get 3 short cables from the devices to the switch and have 2 long cables (1 to the receiver from the switch, and 1 from the receiver to the TV). Or is there a better way to set this up? Any advice gratefully received thanks.
