Information which based on your experience here and seeing the mistake I was making you had ample opportunity to provide but chose not to. I'm now merely trying to understand everything about this and as Jong1 appears to be really knowledgeable and open to the idea of providing actual technical information instead of up selling RuiPro4K cables, I'm continuing on with that discussion as the numbers don't 100% make sense to me and there must be a good and valid reason for this which I'm trying to find out.
I'm not a troll. If you look at a summary of the discussion since I joined it goes like this:
1. Hi guys after having lots of problems with 18Gbps cables I've found that 27Gbps cables work better for me.
2. Hi Otto, Hi Ratman, who are you and why do you keep saying this is nonsense in a kind of bullying way whilst up selling RuiPro4K cables.
3. OK Otto and Ratman so I think you work for RuiPro, and because I think my test results are 100% correct I'm not going to allow you to bully me into not letting everyone else know that 27Gbps work better than 18Gbps cables.
4. Hi Jong1, you seem really knowledgeable, thanks for the informative information, now that I have this information I can see that I was wrong and my test results although correct for me are actually misleading.
5. Trying to make a mense with Otto and Ratman, but Otto and Ratman continue to kind of bully me.
6. Start engaging in more of a technical discussion with Jong1 as he continues to provide useful and informative information and I have natural questions after having read that information.
That's the way I see it.
If I may paste a quote from someone on the other Forum you keep posting to he summarizes what we've been trying to tell you: As others are pointing out it is not possible to verify claims made on many webpages unless there is some form of standard testing procedure to work too - HDMI.org has its Cable and Production Plant Certification process.
I do not work for Ruipro. Ruipro first came to this forum over a year ago answering some questions about fiber and hybrid fiber cables. What they said made sense (with verifiable documentation) so some brave souls tried their cables because they were looking for solution for 4k HDR at lengths longer than about 30'. The cables worked very well so I started up a conversation with them about shorter lengths, which lead to them sending me some short length cables to test in a real-world consumer setting. We started reading more and more positive results from other members here on AVS and it became quite clear that the Ruipro4k cables, at least for now, were a viable solution for 4k HDR at the longer lengths. That's why we recommend them now for 4k HDR beyond 25' and Premium High Speed cables for runs under 25'.
The issue we have is the way you are trying to convince everyone that a reputed "27Gbps" cable produces more 1's and 0's and thus better pq than a certified and verified cable. Both of which are limited to the speed of the HDMI chipsets on either end. We, on the other hand, are just saying that unless you have a way to prove that the cable can in fact reliably pass 27Gbps, and the resultant pq can be measured, it's just your viewing experience with no verifiable data.
Maybe if you had've started the conversation with something a little less "factual" than an unknown 27Gbps cable producing better pq than a certified cable, and then posted the cable so all could look at it (specs and mfr), there could've been a better dialog.
You did post on the other Forum two cables you said list 27Gbps (but you were vague as to whether those were the actual cables you used). One was from Monster, which has a reputation for making all kinds of claims that can't be independently verified and the other one was from an in-house brand of a large European retailer, akin to Best Buy over here. That, by the way, is what precipitated the quote above.
ARROW-AV is one who has done a remarkable job in independently verifying cables from lots of different mfrs for HDMI 2.0. They are in fact verifying the new Ruipro8k cables for HDMI 2.1 now. His results would be a good place to start.
EDIT: and if I may quote myself from my post #1282
: Welcome to AVS and let's hope that you can find a legitimate cable that will work for you and your specific needs. All we can do is recommend based on our experience and knowledge of HDMI (cables, connectors, and protocols).
That's not bullying.
