Issues with 50' HDMI run

I have a dedicated home theater and ran 50' of in-wall HDMI cable. I do have a conduit, so I can replace the cable easily - just knowing how easily an HDMI cable can fail, or go out of date.

This is the cable I used: https://www.amazon.com/dp/B013SPOBX0...018DS1PZO?th=1

It's hooked up to a JVC X570 Projector at one end. A Marantz 7702 MK2 processor at the other.

I can't seem to get it to work. I've tested with an Apple TV.

- The Marantz produces a picture through the 50', but it's only 480p
- When the Apple TV is hooked up to the processor via the 50', there's no picture (and the Apple TV is only set up for 1080p right now, projector supports 4k HDR signal)
- When the Apple TV is plugged in DIRECTLY to the projector via the 50', there's no picture
- The Apple TV hooked up to the projector with a short cable is fine

So I've concluded it's likely this long run.

I tried this from Best Buy, and it did not work: https://www.amazon.com/dp/B013SPOBX0...018DS1PZO?th=1

So I figure I have a few options:

- Get a better repeater. Any recommendations would be great.
- Get a shorter cable. It will be a pain to rerun through the conduit so I'd love to avoid this. But I could probably go down to 40'. I had quite a bit of excess cable in the closet where the gear is.

Any recommendations would be great!

50' can be difficult for any cable. The links you provided are to the same passive 50' cable. It's good you installed a conduit because that will certainly help in installing a new cable. Video technology will always outpace connection technology so finding a cable to work with all devices and setups can be a bit of trial and error. No cable mfr can guarantee that their cable will work 100% of the time with all setups regardless of their slick marketing and product promises.



Make sure that your HDMI connected devices have the same HDMI chipsets at source and sink. IOW, HDMI 2.0 to HDMI 2.0, not HDMI 2.0 to HDMI 1.4. If the chipsets are different, you will only be able to use the in-common protocols which can cause issues.


For the HDMI cable, certification by HDMI.org for passive cables is only good up to 25', so you won't be able to find a Premium High Speed HDMI cable beyond 25'. Active cables cannot be certified by HDMI.org at any length. Do not daisy chain your cables either, especially an active cable.



The most reliable run, especially for 4k HDR, is a single cable from source to sink, with no wall plates, extenders, or adapters in-between. That's not so much of a problem for HD (1080) but 4k HDR and beyond can be really finicky with its connection.


At 50', for 4k HDR, the recommendation is to use a hybrid fiber cable (Ruipro4k). However, they are expensive but do have very favorable reviews from actual AVS users.

I never trust an atom, they make up everything.

Get a 40-50 ft fiber optic HDMI cable. Ruipro is a good one as is this one from Furui.

The posters above are correct - for anything over about 25 feet you'll need a fiber optic HDMI cable for 4K/60. I even had some issues with shorter HDMI cables that were a couple of years old.

Is this a recommendation from your personal experience?

Yes I have owned two of the Furui cables, a 30ft and a 50ft. Connected to my Epson 6050. I personally have not tried Blue Jean's but @biglen has used his BJC with his Epson 5050. Ruipro is well known in the JVC 4K owners thread. I lurk there most days in envy. I gave the 50 ft to a friend and it works great with his JVC NX7.

That's good. Thanks for the clarification.


What BJC cable? Who is biglen?

Blue Jeans Cable. Big Len is just a friend who can vouch for the BJC cable.

BJC does indeed make good cables. I have not tried any of their hybrid fiber cables (didn't know they made them) but have used their Premium High Speed HDMI cables and they worked as expected.


I have heard of Furui cables and looked into them a bit.

I don't think blue jeans makes any Fiber Optic Cables they are just mentioned as an alternative to fiber optic for longer runs

Do you have a link or info on that particular cable for BJC?

Thanks for the clarification. I didn't think they did but it's been awhile since I've been to their site. In my testing of same length BJC Premium High Speed HDMI cables to the Ruipro4k I found that the performance was the same. That's why I'd recommend their certified cables up to 25'. After that, I'd recommend the Ruipro4k.

Wireworld makes good cables from user reviews. Their 40 ft cable is $300. Not inexpensive.

The Wireworld cable referenced above is a passive cable with basically a voltage inserter at the sink end. At 40', and at that price, I'd still recommend a hybrid fiber cable, which is active. $300 for a 40' cable is expensive, especially if there is no indication of how the HDMI 2.0 options sets were determined. If it works as expected that's all that matters.

Thanks everyone, I wound up getting a 25' Ruipro. I actually wound up way overshooting what I needed in length.

I think a normal cable would've been OK at that length, but I didn't want to take any chances.

It's an active cable, it has a USB dongle that is plugged in my case to the back of my projector.

As you said if it works then that is all that matters, i would rather spend a bit more on an HDMI cable especially a long run like this one from my PJ to my AVR than to buy a cheaper one and experience issues.

Yeah, the USB dongle is either just a voltage inserter or it has the active chipsets embedded in it. Hybrid fiber (which is not cheap either) is probably the best bet for long run 4k HDR, but if the Wireworld works, for now, then stick with it. Cost doesn't always mean reliability.

The Ruipro works perfectly with 4k 60hz 4:4:4 over 25'

I had a scare where I thought I may have bent it and broken it when I was passing it through the conduit, but thankfully it works.

The Ruipro cables are very flexible. Glad that it works.

My experience is different.
At the advice of many in this forum, I picked up a 50’ Ruipro. It works at 4:2:0 between my Apple TV and Samsung Frame, but fails at 4:2:2.
