What hdmi cable do i need for 4k uhd tv.
A video game console.
An hdmi cable is just a conduit between your tv and media device be it dvd blu ray or 4k uhd blu ray player.
Hdmi 1 4 if you want your hdmi cables to support 4k resolution you need to make sure that they are high speed hdmi cables.
So even if you bought a high speed cable when all your gear was 1080p and hdmi 1 4 it will probably work now with 4k hdr and hdmi 2 0a gear.
There is a premium certification as well but it is completely optional.
Either by word of mouth from a salesperson or looking at advertising online you may have seen cables labeled as hdmi 2 0 or specifically billed as upgraded cables designed for hdr video 4k video ultra high def video or whatever other buzzword the manufacturer or salesperson felt like throwing around.
With or without hdr you need high speed hdmi cables.
The good news is that cheap hdmi cables are perfectly fine and you don t need an expensive hdmi cable for most tvs including new ones with 4k resolution high dynamic range and dolby vision price.
