TEST REPORTS | LONG HDMI CABLES WHICH PROPERLY AND RELIABLY SUPPORT 18GBPS & HDMI 2.0b


HDMI version 2.0b, which is the currently industry standard, requires 18 Gbps video bandwidth support.

But a great many medium to long length HDMI cables that claim to fully support this in reality do not.

The purpose of this thread is to provide a resource database, including lookup tables, with the results of comprehensive evaluation and testing of HDMI cables to reveal which cables will actually reliably and consistently pass 18 Gbps bandwidth video signals and hence properly support HDMI 2.0b video content. Where you can rest assured that these will every time fully and properly support HDMI 2.0b / 18 Gbps video signals; and hence if you use these cables you can kiss goodbye to all of your HDMI headaches and problems, for good.

Please find attached to this post HDMI Cables Performance Evaluation & Testing Report

Enjoy! :)

This thread will be a terrific source of info for years to come, thank you.

Suggestion. I assume the actual report will be updated many times in the future. Perhaps add the date of the linked report to the file name so people can note an updated report from their last view/download ?

Or perhaps a report version number, e.g V1.0.

Great minds think alike! You will note that the report is labelled "REPORT #1"... The next will be labelled "REPORT #2" ;) :)

good to see...

... for us in he metric world... I so wish that 2nd category was 10m.... rather than 9m... :D In this side of the world... no one buys 9m cables ... its 10m or 15m or say 6m and below if looking for a short one. And do hope mono price get a 10m out at some stage in the range that worked :)

Well you will be pleased to hear that our next evaluation and testing exercise which will be featuring in our next REPORT #2 will be focusing on cables with lengths ranging 6 - 10m / 20 - 33ft ;)

Everything will then be covered, in that there is no need to go shorter than this because the "HDMI PREMIUM Certified Cable” certification currently covers cables up to 15ft/4.5m in length, but not any longer than this as of right now. :)

Great report. :)

It's good to see there are reliable options that are not crazy expensive. It's also clear that there are no reliable cheap options at these distances. The old adage "all HDMI cables are the same" really does not apply for UHD and it is a shame that all the ancient articles arguing that point continue to come up in newcomer's searches and probably will for a few more years!

I'm a bit unsure about your "additional" recommendation. It seems that although the Gigabit Accelerator was able to "fix" some, presumably borderline, cables, it clearly failed in a number of situations too. At it's current cost it only makes sense, as you say, when there are pre-installed cables that are hard to swap. Since a lot of pre-installed cables are likely to be quite old the failure rate might be very high! Personally, based on your results, I would call the Gigabit Accelerator section "Might be worth trying", rather than "recommended" and I would add that anyone trying this to make an old cable work should make sure they get it from a source with a good quibble-free return policy, as it is quite possible it will not work and you really do not want to be left with a $300 paperweight!

Repost with more data and grammar correction (Grin - Arrow-AV quoted me too quickly.).

System is Oppo 203 straight to JVC RS500 projector. *All results* still pending long term testing, and may not be applicable to your system. I merely want to add to the database.

1. Monoprice 25 ft: "Certified Certified Premium High Speed HDMI Cable, HDR" as described on ebay, $29. Doesn't work. Full refund given by official ebay Monoprice seller.
2. OLD Blue Jeans Series 1 about 40 ft: This 5 year old cable is labeled "Series 1." I did not realize that there have been different versions of Series 1 cables: old (Series 1) and new (Series 1E). This is the old version and it's not a surprise that at 40 ft it doesn't work. (It's my hometheater's existing cable that was pulled through wall a few years ago.)
3. Generic No Name HDMI Cable 10 ft: Says HDMI 1.3 on the cable (!!). Don't even remember where it came from :). 10 ft - Works perfect. That this cable works is key to me regarding high speed HDMI: for once in life, shorter is better LOL. Pending others' input, I would speculate therefore most generic short length cables should work for high speed HDMI function.
4. NEW Blue Jeans Series 1E 25 ft: This latest cable is labeled "High Speed HDMI Series 1E". Note the E. 25 ft - Works perfect.
5. NEW Blue Jeans Series 1E 35 ft: "High Speed HDMI Series 1E". Note the E. 35 ft - Works perfect. Very happy with this.
6. Generic 10 ft HDMI + HDFury Linker + Blue Jeans 1E 35 ft: For those, particularly JVC RSx00 (cheers), who use the Linker. Here Linker also acts as a bridge to extend connection to 45 ft - Works perfect.

In number 6, my earlier "theory" of using Linker as a bridge to lengthen copper HDMI connection was tested and worked out perfectly.

Absolutely agree with everything you say here :)

I think it's worth bearing in mind from where we are coming, namely the pre-existing recommendation has been Celerity Tek fibre optic cables. Where both cable recommendations resulting from this initial evaluation and testing exercise are in fact less than HALF the price of the equivalent Celerity cables! So we are very happy that this has achieved our target objective with respect to sourcing solutions that are both more reliable (check!) and less expensive (check!) as compared with the current recommendation. Where the associated cost with respect to say for example the 50ft/15m length cables has dropped from 400 bucks to 'only' 160 bucks. Not bad at all considering the prices of the cables tested ranged up to including 900 bucks for a single cable! So it's great to see the usual 'more-expensive-does-not-equal-better' phenomenon is applicable in this instance and to see cable towards the lower end of the pricing spectrum winning with respect to best peformance ;)

You're absolutely right with respect to what you are saying about the Gigabit Accelerator device. Firstly, given its considerably more expensive as compared with the two recommended cables this would obviously never be even considered if new cables are being installed. But we do see a use for it when seeking to upgrade a system that is already installed and where the cable(s) is/are sealed into walls and/or ceiling and hence where replacing the cable with a new one would entail opening up walls and/or ceilings. But you are correct that it's a bit hit-or-miss so what we intend on doing, (which is what other AV dealers / custom installers might like to do) is to hold stock of one or two of the Gigabit Accelerator devices and when presented with such appropriate circumstance you can simply test what is it's functionality with respect to the particular customer's existing HDMI cable and if it works then the customer can purchase the device and you install it for them; but if not, then you install a new cable for them instead. So we are only recommending it for these specific sorts of circumstances :)

Given that long cables are often used in-wall it would be useful to know the specific ratings of the cable. For example, from what I can see two of the most appealing cable series (Monoprice and RUIPRO fiber optics) may not be explicitly rated for in-wall use.

For example, the Monoprice 21566 is flame tested to VW-1 but doesn't carry a CL2/CL3 or equivalent rating, and the Monoprice website (http://support.monoprice.com/link/portal/41053/41056/Article/1027/What-are-the-fire-safety-ratings-that-your-cables-are-available-in) states:

"However, a VW-1 rating does not necessarily mean that the cable is safe to run in wall"

The external diameter / width of the Monoprice cables measures 3.5mm... Plus the cables are also highly flexible...

Therefore, you don't have to run it in-wall. So if you are worried about doing so, then quite simply don't! ;) :)

Yes, those Monoprice cables clearly have some magic in them and I think it's great Fiber has come down in price. Somehow I suspect that ALL HDMI 2.1 cables will end up being fiber with integrated conversion at the ends, like RUIPRO, at least over 1-2M. Can't see how electrical cables are going to cut it. Sounds like there is some work to do to even get (consumer-priced) fiber to work at 48Gbps though!!

Shhhhh! Don't mention 48Gbps! Everytime anyone does that I immediately go cross-eyed and suffer a spontaneous migraine headache! Best not to think about such matters! ;) :p

question about shorter cables that reliably support 18GBPS

I need 12-15 foot cables to connect a Kaleidescape Strato and OPPO 205 to a Sony 940D

10 foot cables work fine but when I go to 15 foot length, only the certified premium cables work: and they are too thick/heavy:
a slim cable would work but I have yet to find one that is certified premium

any suggestions?

In number 6, my earlier "theory" of using Linker as a bridge to lengthen copper HDMI connection was tested and worked out perfectly.

Ran my 3 ft HDMI + Linker + Blue Jeans Series 1E 35 ft, all outside of wall without any problem.

Got a taste of just how fickle long distance HDMI connection is: As my cable "snakes" from projector towards the BD player, at the player's end there are a bunch of other cables in the area: power cables, digital cable, internet cable, etc. If I lower the Blue Jeans towards other cables, I lose signal. If I raise the Blue Jeans higher to separate from others, signal comes back. I didn't want to test this too much for now because just wanted to leave well enough alone, but would add electromagnetic interference as one reason why these long, high speed, HDMI cables drop signal. I would think the prime suspect are the 110 v power cables/lines.

While reading up on this topic, I came across a post in the past of someone testing with Blue Jeans 1E 25 ft that worked fine "outside," then stopped working once he pulled it through the ceiling (apparently a nightmare :eek:); it was a puzzle to me back then. EMI as the cause makes sense out of this scenario. Difference between Blue Jeans *may* be that it has better isolation.
