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
); 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.
Nice idea and whilst we are not saying the it is not possible that EMI may possibly contribute to some degree in some instances towards an HDMI cable have issues passing video signals, please kindly note that with respect to all of our tests in all instances all cables were tested as 'PRE-INSTALLATION' in other words, NONE were installed into walls or ceilings; and the environment has one of the lowest/non-existent EMI you can possibly find within a residential environment. (Happy to elaborate if you wish).
But please do not misinterpret our saying so as implying that you are imagining things… Where all we are saying this that we can rule out EMI as being an influencing factor with respect to our evaluation and testing exercise. And that if it does indeed transpire to be an issue then this would simply be yet another thing to add to the list of possible causes of cable signal failures

Hi Mark, We would recommend the 6m long RUIPRO. Whilst you don't need it 6m long the cable is highly flexible, very thin, and 100% reliable. It’s perfect for your needs.
Regarding the premium certified cables, we would like to know more regarding precisely how and to what extent these cables are tested, plus wait to hear a sufficiently considerable quantity of feedback from users, plus carry out some of our own tests, all of which before we ourselves will personally be vouching for these cables.
Sorry, if we are ‘Doubting Thomases’ in this regard but we have experienced too many instances of things that are supposed to deliver whatever performance only to discover that the reality is that in practice they fail to do so… Where we both hope and expect all of these cables to all pass 18 Gbps 100.0% of the time consistently, reliably, and without exception, but we just need for our own peace of mind to make absolutely definitively positively sure

We’d like to thank everyone for their kind words and positive feedback. We are nuts about AV and like to be able to positively contribute to AV communities like this one

For what it’s worth, we already have word that one of the Celerity cables that PASSED our testing which we provided to a business associate for installation into his company’s showroom facilities, was working initially but also subsequently failed… and they cost GBP £400 here in the UK! Given our experience to date we have concluded that they unfortunately are just not as reliable as some people think they are…
That said, we should add that same applies to fibre optic HDMI cables in general, in that whilst it is definitely the superior technology regards succeeding in reliably delivering 18Gbps, it cannot be taken for granted or assumed that any and all fibre optic cables will deliver the same perfect perrformance as eachother, because we have already determined that there is a significant variance in performance between the various fibre optic technology based HDMI cable products that we evaluated and tested, and so there is still the need to cherry-pick the cables which are confirmed by tests and/or indicated by user feedback to be the best performing.

Yes, however that's a royal pain in the arse for everyone concerned... especially as compared with using a cable that delivers nothing but perfect performance every time... where we even found the (possible) need to connect power via USB to be an additional negative, let alone the now proven unreliability and cable failures... So sorry, but we won't be buying Celerity again and neither will any of our business associates or clients...
