Hey Guys,

After a quick bit of help cutting through the noise of HDMI standards and fake advertising.

I need to run a HDMI cable in my wall for my TV before I put the Jib on, cause once the jib is on there is no going back- I cant run conduit to put one in after as the cable wouldnt make it.

I want to future proof and put in a 8K HDMI cable that is about 15m long, does such a thing actually exist?

HDMI 2.0b or 2.1 will do it. 2.1 to be safe.

I believe you will need an HDMI 2.1 capable cable.

Look for gear with HDMI 2.1 support. Think it's 48Gbps they can handle. 15m though, that's not likely....maybe 3m if you are lucky at the moment.

Edit - Dynamix have up to 5m.

The problem is none of the standards required for 8k have really been finalized yet. Perhaps look to design the setup in such a way that a cable can be replaced easily. Maybe run a conduit especially for the HDMI cable.

Would the 15m run be for a projector? If so, you are quite likely to need a splitter/amplifier too, which probably doesn't exist yet for 8k.

From my experience from 4K don't expect to future proof. I had trouble getting a good quality 6m cable to work properly at 4K.

Future proof by running ducting that you can pull a new cable through.

'Thirded' the advice to run conduit.

I seriously doubt there's any suitably tested 15 meter 8K cables on the market, least from Dynamix...

The new spec was designed to run the standard distance for HDMI - ie the length of the designers desk.

Everything beyond that is un-tested water.

This is exactly why the industry needs to be quickly moving towards video over fibre. But, cost... although, you'd think it would fall quickly if it became a standard. Rant over :)

Thanks so much guys, I sent the sparkies of to the wholesalers but their top quality cable was HDMI 2.0 10 gbps throughput

Im just seeing what I can get online now, if only Dynamics had a 15m one of these but even a 18gbps will be an improvement

Edit: at this point I might order something form overseas, it looks like I can get a Fibre HDMI 2.1 cable to do the trick - if anyone has any recommendations, dont be shy.

Don't put anything in the wall until you have thoroughly tested it, at 15m i suspect you will be fine for 1080p but that's it, set your expectation at that otherwise you will be disappointed. I had success running an optical audio return from my TV to my receiver for 4K content on my TV (Native Apps) I suspect this is the future for us (Native, or dongles like the Fire stick 4K), and not trying to do long HDMI runs. I've effectively given up trying to go 7 meters for 4K.

Have a HDMI 2.0 in my wall after replacing a 1.4, it's 15 mtrs long with no conduit and goes to another room where I keep all my equipment. Just make sure the holes are in line and you should be able to pull a new cable through, that's how mine worked anyways.

I have 4K60 Dolby Vision at 15 mtrs. You just need to get an Active fibre Optic HDMI cable, standard copper won't do it. Active Fibre Optic are also directional so make sure you put it in in the right direction. This is the one I have https://www.amazon.com/gp/product/B07287LTRZ/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

Yeah, I worked out you need the fiber version for the long lengths. Copper only works for <3m.

Do you have any brand recommendations?

That is good to know that you were having success with that cable, I was looking at a 10m one but wasn't willing to commit, without buying one that I could easily return.

What do you have at each end of the cable and what 4K sources do you use out of interest?

With my current cable I found playing a 4k HD disk would play fine on my TV from an 'Xbox One X' but if I tried to game on the Xbox the signal would fail.
