Another AppleTV 4K HDMI cable question

[GIZBUG]

Not able to get chroma 4:2:2 and the display on my Samsung Q8FN w/ Denon X2400H receiver flickers / blank screen sometimes.

Was told to replace the HDMI cable. So I bought the belkin ultra HD from Apple, and ran it from appletv 4k to receiver. Same issue. So now I’m looking to replace the cable from tv to receiver. The belkin is 6 for long. I need at least 15ft to be safe. Any recommendations so I can get this issue fixed and not have to rerun cables again (cable is in the wall)?

Thanks

So i had the same issue, but my problem i already had all cables run in the walls. I have a 50 ft hdmi cable running to the receiver.
So after extensive research i ended up getting a fiber optic hdmi cable and now getting full 4:2:2 and HDR

That Belkin is over priced. Any cable that is certified for the intended use will do and cheaper are available. There is the maximum distance any HDMI cable can be certified for (10' I think? Edit. Should be Yards, so 10 yards. Apols). If it works at 4k full fat longer than that crack on but it would not officially be certified and you take a chance buying it (free returns for non workers would be handy).

However, can you connect the Apple TV direct to the TV with the cables at hand to prove the cables or the receiver. Even if it is a lash up just to test it.

Are your cables all to the spec for the signal you want to your TV?

i got this one in 50FT comes in 25. I couldn't be happier now that I have full HDR 4:2:2 i can't really tell apart. Before when i turned full HDR and sub chroma on my Yamaha receiver everything just went black. Now everything works and when I run through apple tv test cable feature, it fully supports everything.

Thanks. Says cable isn’t bidirectional. I’m not sure if that is an issue or not. A bit pricey, but maybe you get what you pay for

HDMI cables are a nightmare. Certification to a standard doesn't guarantee that it will work in your environment.

I fixed a similar problem that I had with my DirecTV box by replacing the cable from my Yamaha to the TV with a better cable.

As you move to a longer the cable you also have to increase the cables quality, as implied by goudok. Here's a quote from an email exchange I had with Audioquest 2 years ago. May not be current, but shows the problem:

"The cable that carries that signal can still be improved upon. It is still at basic principles a signal that consists of voltage and current. If the cable material is inferior it will be a hindrance to that signal. If you improve the cable material and shielding. It will flow much better and provide a better signal."

"All of our HDMI cables up to 10m are high speed according to the HDMI org standards for spec 1.4. Spec 1.4 provided that the cable would be around 11Gbps and above and would work for 4K and 3D but would only allow about a 30hz frame rate. Now we have spec 2.0 which provides for speeds “up to” 18Gbps. This improves on the previous 1.4 spec but also allows faster frame rates for 4K. We have sent in our cables for certification and we have received back that our 5m lengths and below can handle the full 18Gbps speed. Anything beyond 5m and up to 10m would be slower than 18Gbps but still above 11Gbps which is still high speed per the 1.4 spec."

If you are concerned about 4K and want the full 18Gbps than stick to our 5M lengths and below. If you think you are ok with 1080P and /or slower frame rate 4K/3D than you can go up to 10M in length. Anything beyond 10m will be standard speed cable and can normally only handle 1080i not 1080p."

And here are two old cable tests, showing that a lot of cables fail:

Check that your TV has 2.1 hdmi enabled as my TV default was 1.4. I ran through several cables before realizing that a TV setting fixed my issues. Currently using this cable in 6ft and 3ft:

A very quick check on the user manual for your TV states:
For watching HDR content via an HDMI connection, it is important to set the 'HDMI UHD Color' on for each HDMI input that will receive the HDR content. This will permit the HDMI port to transmit all the bandwidth needed for HDR and tells the TV to expect a 10-bit color signal on that input. If the 'HDMI UHD Color' is not turned on, some devices will not detect the Q8FN as being compatible with HDR. For HDR content, it is also preferable to set the 'Backlight' to maximum, set 'Local Dimming' to 'High' and set the 'Color Space Settings' to 'Auto'.

I really would test out the existing cables first, and assuming they are the correct specification for your needs, some basic testing at least. Bypass the amp and go direct to the TV and prove the TV and Apple device will work together for the settings required. Then build on that test.

I Know nothing about amps but in multiple device systems, make it simple then test. Lead works at the correct rate to the TV from the Apple TV then the lead is OK and there is another issue somewhere.

Edit. I did say 10' earlier, it was wrong. Should have been yards. Apols.

Bi directional absolutely matters. It can only go one way. But how is that an issue? You just have to read the labels on the end of the cable.
Under 6 feet i dont think it matters as long as the cable is high bandwidth. I never spent any more than what I had to on a cable, but now this is costing me way more than a cable since I had to open up walls again.

In case this helps, I was able to get Chroma 4:4:4 in 4k SDR 60Hz (my TV doesn't support HDR) on my Samsung TV with this cable.

I did have to turn on UHD on the HDMI input for it to work.

I learned that lesson as well. The second time I ran a straight conduit to attic. Now I can push/pull just about any cable quite easily. Cables will fail, you will add something else in the future.
