Hi, I'm looking for hdmi cables that definitely work with the ATV4K for HDR10 and Dolby Vision. There's lots of difficult info online, I'm looking for cables that are confirmed to operate correctly. I need a few shorter ones (6ft or less) and one 10'-12'.
Thanks
Any HDMI cable that is truly 18 Gbps should work. Nothing wrong with extra labels and testing, but HDR or Dolby Vision is not a cable property. Bandwidth is the factor that matters. The HDMI 2.0 port on your Apple TV 4K will never exceed that 18 Gbps limit, as these devices have to comply with the HDMI standards that specify these things.
While Belkin sells the Ultra High Speed HDMI cable (48 Gbps), they also sell the Premium High Speed HDMI cable (18 Gbps), that would work just a fine for this.
Any other brand is fine too, as long as you can trust the bandwidth specification on them.
Don’t get the ‘High Speed’ (10.2 Gbps) or ‘Standard’ (4.95 Gbps) cables though.
I found this on Apple Support on a page titled, "About 4K, HDR, and Dolby Vision on your Apple TV 4K".
Check your HDMI cable
4K video, especially HDR10 and Dolby Vision, requires an HDMI cable compatible with these formats. Apple recommends HDMI cables that have the Compatible Dolby Vision mark as they have been tested with Apple TV 4K and a wide range of televisions. An example is the Belkin Ultra High Speed HDMI Cable.
If there's an issue with your HDMI cable, you might see a message on your Apple TV that says that your HDMI cable might be having trouble maintaining a stable connection. To check your HDMI cable connection, go to Settings > Video and Audio and select Check HDMI Connection to run a 2 minute test.
If you still experience issues with your HDMI cable connection, check all of your connections and make sure that your HDMI cable has the label “Compatible Dolby Vision.”
There seem to be a lot of people having this issue if they use a high speed premium cable that is certified for 4K/HDR and has a data rate of 18GBPS but it might not be specifically compatible with ATV4K and Dolby Vision. Maybe this issue has been fixed in an update. I was hoping for suggestions of brands other than Belkin that might have Apple's stamp of approval “Compatible Dolby Vision”. I do recognise that other brands might not exist.
Thanks
You will need a high speed premium cable that is certified for 4K/HDR and has a data rate of 18GBPS.
