6 Meter HDMI 2.1 cable Do they exist ?

[Grim5]

To answer OP's question, yes you can buy HDMI 2.1 cable up to 100meter

Thanks for the replies, yes it seems 5M is the limit, unless you go optical hdmi 2.1 ?
I wonder if anyone has tried optical hdmi 2.1 from GPU to TV ?

Seems like its my only option short of moving the whole hifi rack.

For a passive copper cable, 3 meters is the limit (unless you enjoy black screens or green artifacts on your screen). Anything over 3m should be an active cable.

And yes HDMI cable is backwards compatible so you could use a 5m meter passive copper cable with an older HDMI 2.0 device just fine, but plug in a shiny new RTX3080 and you will get artifacts and black screens

these are the only ones ive seen that people are reliably saying will carry the higher bandwidth signals. The require you to plug them into a USB port for power.

I'll be getting one of these if a company ever wants to take my money for a new card......

As folk have said; 3m is about the limit for 2.1 unless you go fibre. Some folk have had success with up to 5m, but it really is a gamble - you can't reliably do it.

Just to happily report!
My cable arrived from the states and I plugged it in and....It works straight away!
20 foot Fiber HDMI Gen 3/B Cable from Ruipro, is currently supporting 4k 120hz 10bit & Gsync and HDCP all working.
I can now move my PC back to the Hifi Stand, yay!

Maybe OCUK should conciser selling this brand.

P.S I didn't need the USB power dongle that comes with the cable, it worked without it.

This was going from Ampere 3070 to Oled B9

 

[ik9000]

does it need supplementary power from usb/mains?

 

[LaRZ]

ik9000, it worked without the usb dongle it came with.

 

[ik9000]

have you checked it's giving you the full frame rate?

 

[LaRZ]

Yep, 120hz
Only thing I haven't tested is e-arc, but it says on the box it supports it.
It also supports 12 bit just checked that works, but is a bit pointless for me as the B9 only has a 10 bit panel I believe.

If buying this cable it must be ordered from Amazon US and be a Gen3/B cable.

a hundred quid for an 18Gb cable eek:

 

[LaRZ]

Its 48gb, but Ya at $200 its the most expensive cable I ever purchased, but money well spent as it works perfectly.
P.S no one should be buying these cables unless you need more than 3m on hdmi 2.1 48gbps or you get interference on your current copper cable.

I have had HDMi cables black out from wifi interference, which as I understand it, cannot happen with fiber.

 

[james.miller]

The cable streetlow linked to is 100 quid. Well, 110. For 1m. But away, you can get a 3m 48Gb 2.1 ultra certified cable from kabeldirekt for 20 quid. 7-8x the price for a 6m cable., active or not... nope. nope nope nope.

Sorry yeah the link to the page defaulted it to 1m but the options are there for the longer cables.

You're right, over a short distance <3m i don't think its an issue. Anything over that and the cheaper ones are going to start producing problems.

 

[LaRZ]

Yes if you only 3m hdmi 2.1 cable = I would stick with copper HDMI 2.1.
If you need more than 3 meters and need full spec 48gbs speeds, I would recommend optical.

Also this optical cable is easier to route via conduit as is a lot thinner cable.

I'm after a 10 metre 2.1 cable, this company/seller says they will being doing a 3000 series compatible one soon,

https://www.amazon.co.uk/dp/B07VRQP...colid=29HS78OXJW61Y&ref_=lv_ov_lig_dp_it&th=1

If look at the question/answers section the seller/maker says one month, that was posted on the 3rd of January.

As for smaller cables @ 2.1 spec I've been using the following,

https://www.amazon.co.uk/gp/product/B082775CMS/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

They've been working very well.

This is the only passive 5 metre officially certified full fat 48Gbps cable that I know off.

Have you tested it? That's pretty cool if it works but I wonder how they fixed the line signal noise over that length.

I did look at the Amazon reviews

there are people with Xbox giving 5 star and people with rtx 3080/3090 giving 1 star so your mileage may vary

I've not tested the Zeskit one, I have a 2 metre UGREEN one I linked above that works fine, 4k 120hz with 3080, I'm waiting for the ConnBull (first link) to get their 10 metre 3080 compatible cable in stock and I'll purchase that and will test and report back.

What I don't get is that the Zeskit one is officially certified, but as you say people in reviews are saying it isn't working with their 3000 series GPU's, then what is wrong?, does the offcial certifcation only take into account home cinema use case and not GPU's?, ConnBull have their cable specced as full 2.1 48Gb/s, yet acknowledge that a 3000 series compatible cable is coming, so what do you presume is the difference is these cables that make them 3000 series compatible?

HDTEST vouched for zeskit?
