I saw the test results in this forum and this particular cable doesn't pass for a full signal 18gbps, but I'm wondering if anyone is still using it with success on 4k content (assumption being that not all 4k content is eating up 18gbps)? I have a JVC RS400, Marantz SR8012, Monoprice Cabernet 40', and just ordered a Panasonic UB820. The Panasonic will send a 4k signal without sending a HDR signal, if that makes any difference. I think I can force it to 24fps.

Anybody with a similar setup having success, or is everybody with a projector run using fiber optic?

40' is getting a bit long for 4k HDR for any cable. The hybrid fiber cables from Ruipro (Ruipro4k) are getting the most favorable results. At 40' are you running your cables in a conduit or do you have easy access to them? The most successful connections are a single cable, source to sink, with no extensions, adapters, wall plates, etc in-between the source and sink. Distance is the achilles heel for 4k HDR. The longer the run, the more apt one is to have issues. The hybrid fiber cables are active.
Certification for passive cables is only good to 25' so you won't find any ATC certified cables longer than 25'. Active cables can not get the ATC certification.

The cabernet is active - I'm unsure of whether mine was Redmere or the newer Spectra 7 at the time I bought it in spring of 2017, but I'm thinking it is Redmere.

The cable was run in a conduit, but if my memory serves me correctly, on the last horizontal run to the projector in the middle width of the room, I went bare cable and used some connectors nailed to the ceiling joist. I'd imagine those could be yanked out with enough force even though I can't get to them. I would need to secure a new cable to the old cable and pull the old cable out.

Are people having success with the newer Spectra 7, or is fiber optic the only answer?

Some have had success with the Spectra 7 chipsets so you’ll just have to try. Do keep in mind that active cables should not be daisy chained as that can introduce errors and is not recommended by most cable mfrs. If it were me I’d go with the Ruipro4k cable and keep it a single connection, source to sink.

You seem to enjoy saying “source to sink” lol. I run certified premium HDMI cables into the receiver, and then the active cable from the receiver to the projector. The panasonic does have 2 hdmi outs and the jvc does have 2 hdmi ins, so “source to sink” may be possible.
The receiver can be both, sink when a cable is connected to it and then source when the cable goes out to your display. What you don’t want is any extenders, adapters, etc in-between cable connections to or from the receiver.

I own the Panasonic UB820 and use it with my Epson HC4000 4K projector (10.2 Gbps). As long as you restrict the UB820 to 24fps you should be fine. Originally I ran it successfully with an older 50' Blue Jeans high speed cable. Later I switched to a 50' Ruipro Hybrid cable because my next projector will have the full 18.2 Gbps chipset. As others have said try your current setup and see if it works with the UB820. Problems start when you try pushing 4K/60p.

That’s the good news I was hoping to hear! Unit should arrive Tuesday and I should be able to test Wednesday. If it is established that 24fps without HDR signal maxes out below 18gbps, then I think this cable can do the job.

Was the Blue Jeans cable active or passive?
The Blue Jean cable was passive. As long as I restricted my datastream to 24fps I was able to get 4K and HDR on my Epson even from streaming devices. Here is an older screenshot I took when I was using the Sony X800 (4K) Blu-ray player with the Blue Jeans cable.

So it likes 4k, 60hz, 4:4:4, no problem!

Monoprice certified premium 6’ from Panasonic UB820 to Marantz SR8012, then monoprice cabernet 45’ to JVC RS400. Success!


Steve I’m digging up an old one here but you seem to be using the exact same cable that I now have in wall and I’m not able to pull. Just bought a new 4K TV so I’m anxious to dig a little deeper on this.

Is your Cabernet cable still functioning well? Ie Are you still consistently getting 4K, HDR, at 60 frames per second with 444 chroma with no issues?

What I primarily need to achieve is 4K, HDR, 30 FPS with 444 chroma. I have the exact cable you have, bought at the same time from Monoprice, mine being a 40 foot long cable. Thanks in advance with any help on this old thread.

As you may be seeing, no cable is guaranteed to work 100% for all setups and connected devices. As I mentioned above, if the Monoprice cable, which is active, has the older Redmere chipsets it just may not be up to the task at that length. Unfortunately, it is very difficult to determine which chipsets are installed, the older Redmere or the new Spectra7 (which purchased/merged with Redmere). What is your setup and are you using a conduit, or do you have easy access to your cabling?

Hey Otto, thanks for getting back. No unfortunately this cable is upstairs it’s been finished in whereas I have conduit for my theater I do not for this one. Fortunately for me it seems to be working very well. I’m skeptical of sending it 444 chroma 60 FPS but not too concerned about that at this point. It’s working perfectly 4K60P at the moment.

Unless you're a gamer I don't see the need for 4:4:4 chroma. Movies et all are still mastered for the most part in 4:2:0 that I'm aware of and besides, I don't think one can really tell the difference visually between 4:2:0 and 4:4:4. Maybe I'm wrong.

Yes, it is doing the job great. Mine uses the old Redmere, it is 45' long, I am sending 4k 60fps 4:4:4, but no HDR. My projector can't do anything with the HDR, so I have the Panasonic remapping it.
