hey y'all,
I am asking for any users of the XMC-2, RMC-2 and the soon to be available RMC-1L to post their findings as to the best and most stable HDMI cables they have used with these processors. please let us all know what other equipment you are hooking up to these cables and what lengths you are using. please let us know if their seemed to be certain ones that were considerably problematic. note that many people like me are looking reasonably price cables so giving us a ballpark cost would also be helpful.
Also, Try to just give us the facts..........Since I would like this thread to be as informative and objective as possible.
so for those are eventually add their input.... Thanks in advance.
and as AUDIOHTIT suggested, I am most interested in what has actually been used in the Emotiva Processors XMC-2. RMC-1 and the upcoming RMC-1L.
tchaik.......

As I have put in the other threads, this 5 ft cable from Amazon is rock solid. I have 2 in use, from the Apple TV 4K to the XMC2 and from the XMC2 to the LG OLED. It extremely stable so Dolby Vision is not an issue anymore. I plan on buying another pair for the Sony 4K Blu-Ray player (up to HDR and no Dolby Vision) but for now the other hdmi cable works just fine.

Check out the Belkin Ultra High-Speed HDMI. It was co-developed with Apple. Unlike almost every other HDMI cable out there it uses micro-coax wiring, instead of twisted pairs. I have never heard of anyone having an issue with this cable. Unfortunately it only comes in lengths up to 6ft.

Reos Gear 5 Feet Premium... www.amazon.com/dp/B07BS7KZ3S?ref=ppx_pop_mob_ap_shareIt's only rated for 18Gbps. This will not be HDMI 2.1 compliant (at least for the higher bitrate formats coming). Get a 48Gbps cable to make sure you're ready for 2.1 |

Get a 48Gbps cable to make sure you're ready for 2.1 EDIT: Found it. Ok, I see it can support 8K and more bandwidth. I see what you mean - might be worth it to spend a few more bucks now etc. Can you explain the difference between the Belkin cable you mentioned and the Reos Gear 5 that I am using with zero problems? I tried looking up the specs for the Belkin but was unable to find them. I don’t have any HDMI 2.1 compliant gear (and probably won’t for a long time) so I’m not sure why I need to spend more money now vs later when I replace my TV and update the XMC2 and Apple TV 4K. I feel like I’m missing something with your reply so if you don’t mind clarifying, thanks. |

Finished wiring, setting up and finally dialing in this afternoon with the same Emotiva Z-HDMI cables(1m & 2m) I used with the XMC-1 and the RMC-1 works flawlessly with these cables.

I am most likely ordering my RMC-1 within the next few days and I have a Sony projector. My active HDMI cable is 35' long and I do wonder if it will work out okay. |

Mark said............... I have used the Monoprice HDMI cables, Amazon cables, Best Buy high price cables with varying degrees of success but in the end they work sometimes. About 1.5 years ago I switched to www.bluejeanscable.com/store/hdmi-cables/hdmi-cable.htm and I have zero issues with HDMI. Bluejean cables are high quality at a decent price and start at 1ft for $10.75. Everyone has an opinion so take this for what it is worth, spend $11 and find out Hardware: XMC-1 Oppo 103D (1 ft HDMI) Appletv 4k (1 ft HDMI) Xbox 1 and 1x (1 ft HDMI) Sony VPLVW285ES 4k (25ft HDMI) LG OLED 65B8 Appletv 4k (6 ft HDMI) Roku (6 ft HDMI) Sony X900F Appletv 4k (3 ft HDMI) Amazon FireStick 4k (3 ft HDMI)[/quote] |

Sure, happy to. Specs are on the Amazon listing - www.amazon.com/Belkin-AV10175bt2M-BLK-Vision-Optimal-Viewing/dp/B075N83B9XHDMI cables are confusing as heck because bitrate isn't just about resolution. You also have to consider frame rate, chroma sub-sampling, and HDR to determine your bandwidth needs. There's nothing wrong with your cable and I'm sorry I made it sound that way. If it works reliably in your setup there's no need to change anything. What I was alluding to is that many cable vendors are still trying push high bitrates over twisted pair. There are 4 "lanes" of twisted pair cables in a single HDMI cable. Twisted pair is the same technology used in Ethernet cables. Intra-pair skew (length matching) and inter-pair skew (pair to pair) has to be carefully controlled to ensure that all bits are clocked at the same time. A micro-coax assembly makes this a little easier. And every data line is essentially shielded from interference by the outer shell. There are crazy physics that get into the pros and cons of both. But with the coax approach the capacitance goes up so the cable length has to be capped. What many people don't realize talking about HDMI cables is that desense can be a nightmare. A bad cable (even those rated highly) will radiate harmonics of the HDMI clock. At 4K this just so happens to step on 2.4Ghz WiFI and BT. It means that a bad cable can kill your WiFi or BT signal, and reduce the effective range. Some very poor HDMI cables (do NOT buy Twisted Veins), will reduce the WiFI's receiver sensitivity by as much as 30dB. And the worst part of this is that most cable manufacturers have no clue what desense is. The data may be going through just fine, even at high bitrate, but they radiate like mad. Those cables being made using micro-coax tend to be much better shielded and terminated. |

I have no idea what you are saying...except I am good with the cable I bought. I will buy one of the hdmi 2.1 cables from amazon that’s about $15.99. Maybe that’ll fix ARC on my LG OLED 😬 |

He asked for facts, not a single opinion was stated here. If you had said, I’ve used the Belkin successfully with my XMC-x or RMC-x, instead of ‘check out this’, then it wouldn’t have sounded like opinion. Also discouraging tested and working HDMI 2.0 solutions, because they won’t be ready for 2.1 eliminates a lot of cables that work perfectly, allow for longer and shorter lengths, and are less expensive. I know you are knowledgeable on this subject and I respect that, I just feel that (in this case) the Belkin should be presented as a working solution, that might also work with a future standard. However, other working solutions (cables) should not be discouraged because someday they might need to be replaced (that’s an opinion, as I think your position is as well). |

I am using 2 of them with my XMC-1 for connection to an ATV 4K, and Xbox. Not trying to force any 1 solution on anybody. It's just nice to NOT have rewire infrastructure when new standards become available. If you can future proof yourself for relative cheap, why not plan for it? |

I will add my experience with the XMC-1 V3 (HDMI 2.0b) board as it should be pertinent to the new processors as well. I will also report back Friday when I’ve swapped out the XMC-1V3 for an RMC-1, I have my fingers crossed that everything will continue to work. (It is my understanding that the V3 is the same video board as is in all the new processors) I chose my cables based on these criteria, in this order of importance: Premium Certified High Speed HDMI, 8’ and 4’ length availability, size (thin preferred for routing), black, & cost. As I’d had good luck with Monoprice HDMI in the past I started there and they worked. I use this model because they meet all these needs and come in 1’ increments. Their thin size also makes them very easy to route through my cable tubes. Monoprice Ultra Slim Certified Premium High Speed HDMI Cable 4K@60Hz HDR/18Gbps/36AWG YUV 4:4:4 BlackAll of my sources are in the same part of the cabinet, 6 feet (as the crow flies) from the processor, with cable routing an 8’ cable works perfectly. My sources are all 4K capable, except the older Mac mini: DirecTV C61K, Oppo UDP-203, Apple TV4K, Mac mini (I tested both a late-2012 mini in 1080p, and a 2018 mini in 2160p) My Sony XBR85x900F TV sits atop the cabinet and requires a 4’ cable. Edit 2021-07-07: The same Monoprice cables listed above continue to work well, now close to three years with my RMC-1, and more than a year before that with the XMC-1v3. My TV has been upgraded to the 4KG2 (w/HDMI 2.1 / eARC), and the Mac mini is now the 2018 model with 4K / 2160p output. All is well. |

My hdmi cables work perfectly but I may buy an HDMI 2.1 to see that helps with the ARC issue between my LG OLED and the XMC2. |

Just adding that I swapped out the XMC-1v3 for the RMC-1 today, moved all the cables I listed above (HERE) straight over. Everything seems to be working well, though still have to do FW 1.5. |

I should add that I’ve also successfully used the Freeport 6’ Premium cable that came with my Oppo 203. I keep it handy for adding a test device or troubleshooting.  |
