The Denon AVR-X4400H is eARC enabled.Roy, you've just sort of answered a question I was going to ask - does anything in the consumer space actually use the Ethernet channels on HDMI? To date I've never seen anything that mentions using it in the spec or manual.
Ultra High Speed HDMI Cable
Q: What is the maximum length of this cable?
A: The specification does not indicate a cable length. Cable length depends on the cable manufacturer. It is likely the maximum lengths for passive cables will be approximately 2 to 3 meters.
Q: Are active cables supported in the specification?
A: The specification permits wire, passive, active, and converter Category 3 cable assemblies.
The current FAQ still says to expect somewhere between 2-3m max for copper passive cables. Really hope they properly spec and certify a fibre solution so everyone can know exactly what they're getting. Apart from anything, it will also solve the certification issue for people wanting a certified solution for 18gbps >8m, which just doesn't exist.Back on the 4th Jan 2017 when HDMI.org first announced HDMI 2.1 the press release mentioned 48G cables and in additional Press statements mentioned an expected max length of up to 3m!
HDMI :: Press Release
Once HDMI 2.1 was formalised on 28th Nov 2017 the 48G cable naming had been dropped in favour of 'Ultra High Speed" and no indication of the expected cable length limitations for copper cables.

Thanks for the clarification Joe, thought my 10' cables were useless.'I'm confused, 10' of wire is too much to run from TV to any AV? What's the recommended length?'

HDMI :: Press Release
Current generation High Speed and Premium High Speed Certified cables top out at 8m (26') - once the Certification process has been released cable manufacturers can start to release details on expected cable lengths for Copper, Active and Fibre solutions.
Expect anything much longer than a few meters to be Active or Fibre based.

Thanks, I got some Zeskit high speed premium Cables. So far so good, was just worried I got too much length but it seems I’m good.Blue Jeans Cables Series-FE cables are Premium certified up to 15’ Premium HDMI Cable Certifications -- Blue Jeans Cable, if that’s any help.
Hi does anyone know what HDMI cables I need to achieve 4K 60FPS HDR10 content with the 4:4:4 Chroma??? I've bought so many 18Gbps Certified HDMI 2.0 cables now and NONE of them go past 4:2:0 Chroma. It's becoming very annoying now and I'm beginning to think HDMI 2.0 cables are a giant con!!
I have an LG OLED TV and am using an RTX2070 graphics card to create the graphics content. The LG TV is capable of achieving 4K at 120FPS 4:4:4 HDR pictures, and the RTX2070 graphics card is only running at about 14% capacity so all of my hardware is fully capable, it's just the HDMI cable that's proving to be the weak link.
All of the Certified HDMI 2.0 cable adverts say they can do 4K and HDR and 4:4:4 blah blah blah but I don't care which of the settings the cable can achieve in isolation with all of the other settings turned down, because I want the cable to support all of those settings at the same time like my expensive TV and my expensive computer are capable of displaying
Please help. I've even purchased 27Gbps and 48Gbps HDMI cables and although those definitely work better than the 18Gbps ones, they were both only still able to get me to 4K 60FPS HDR12 4:2:2 Chroma... I mean HDR12 doesn't even exist yet does it, except in Dolby Vision, but I think my TV is only HDR10 so cannot make use of this extra HDR12 content
I mean do HDMI 2.0 ports on TV's max out at 4K 60FPS HDR 4:2:2 Chroma or something??? I've not read that anywhere but is that going to be the maximum performance I can get out of this TV until TV's with V2.1 HDMI ports start being sold???
4:4:4 4k HDR would require 20+ Gbps - HDMI 2.0 taps out at 18Gbps that's why. Why do you think you need above 4:2:0 or 4:2:2??
