    • Fantastic product with an equally amazing customer service.
Color: A-8K Fiber Gen3/C Size: 20FT
So I got this cable back last year as I needed something that wouldn’t run into issues at longer lengths since I needed a 29 ft hdmi cable. Heard great things about Ruipro fiber optic and decided to go with them. Out of the gate, everything worked great but then last week, I had an issue where the screen would go blank and it would revert to the no signal screen on my tv. I reached out to ruipro to explain the situation and I kid you not, they sent me a new one that arrived the very next day even though I was well past the return table on Amazon. I love the cable so I was only wanting it replaced, you don’t find great customer service like that anymore. Super fast connectivity, the length was perfect, I lose nothing in sound either as I connect it directly from my tv to my receiver. All in all, I would 100% buy from them again. They stand by their products and are fantastic help as well. ... show more

Bought in 23 and just stopped working. Now I have to go cord shopping. It is very inconvenient to pull the cord out of the wall and run a new one. Update. Reached out to the seller and they are sending me a new cord. Can’t beat great customer service.

    • Plug the Cable in Directly - No Keystones or Adapters
Color: A-8K Fiber Gen3/C Size: 100FT
Installed this cable in my wall to go from RTX 3090 -> Sony Z9J for gaming (120hz HDR w/ VRR). INSTALL: I had the cable professionally installed, but the install cost me a lot more money than I anticipated due to the size of the HDMI connector. I was hoping looking at the pictures that the HDMI connector was small enough to fit through the holes drilled by my local ISP for ethernet, but no dice. I would love to see a fiber option from RUIPRO that has slim fiber cables and detachable HDMI ends. This would make it so much easier and cheaper to run the cable long distances, and we could leverage existing runs or small conduit to run the cable instead of extensive drilling and drywall tearing. I made sure to work with the installers to ensure the source/display ends were on the correct side, a friend of mine had one installed backwards and ended up having to pay twice. Performance: At first I had a really difficult time getting 120hz / HDR / VRR or any other 'advanced' display output settings to work. I struggled and struggled, changed HDMI ports, format settings, graphics drivers, etc. I realized my issue was that I used (supposedly) 8k capable keystone jacks and 8k cable 6' cables to connect from the keystones to the source/destination devices. This cable likes to be plugged in *directly*. As soon as I removed the keystones and ran the cable all the way to the source/destination I get flawless 120hz with HDR and VRR working in Windows. I also tested 8K on the 8K port and that is working as well. However, on the Z9J 8K is gimped in some cases so I did not test it extensively. 8K/60p works flawlessly. ... show more

    • Unreliable. Bought 2, installed in a hard to get place, one failed at 14 months, and the other 16.
Color: A-8K Fiber Gen3/C Size: 33FT
No, I didn't bother with warranty, and I won't be trying it out. Two failing so close together makes me believe I'd be digging out the new pair another year down the road. No thanks, I'll go with another brand this time. I got the 33' set, at the end of 2020 when hdmi 2.1 was like the frikkin new frontier. These were the only cables on amazon over 15ft that had *actually been confirmed* to work properly. I only needed one high bandwidth cable -- One for PC, and the other is for the switch so I could've used just about any old $10 cable. But the routing is rather a pain, part of it behind my fireplace and requiring minor construction to access, so-- I thought myself being SUPER PREPARED by getting 2 of the ultra bandwidth cables, so if one ever failed, I could just switch to the other - limiting myself to only one input, but at least ensuring I wouldn't lose capabilities. And just over a year down the road, boom- one of the cables just zonked. No throughput at all, any source, end of sentence. I thought, "damn, me! I'm a genius for preparing for just this dire circumstance!" But alas, my self-congratulatory smug lasted only another month or so before the 2nd one followed suit. To be fair, these did work quite well - Used primarily for 4k/120hz VRR+UHD content (pc), and it did a lovely job. Until it didn't and I had go cable spelunking :( Here's hoping the big well known cable brand (which now has an active 2.1 certified cable available for less than this one) lasts a little longer, but hey - if not, at least Ruipro gave me some practice pulling my fireplace apart, right? :D ... show more

    • Fixed my video problems
Color: A-8K Fiber Gen3/C Size: 33FT
To begin, if you are looking for an HDMI cable for runs of greater than 15-20 feet, don't want to do HDMI over ethernet, and want a great picture on your HDTV, then look no further than the RUIPRO 8K active hybrid fiber optic HDMI cable. After inadvertently damaging my older 25 foot copper HDMI cables that I thought was giving me a great picture on my 75 inch Samsung Q80TA, I researched new cables and decided on the 10 meter RUIPRO 4K/60 Hz (You read right; the 4K cable). The quality of the materials was first class. (Don't be swayed by reviewers who think that a thin cable is a cheap poorly made cable!!) When I tried to set up the cable with my DirecTV 4K Genie receiver, I was unable to get support for 1080p and 4K resolutions. I tried the usual suggestions such as unplugging the cables and the TV and restarting everything. That did not solve the issue. I contacted RUIPRO and they sent me another cable. Same results. I contacted DirecTV and Samsung without any help. They seemed totally clueless about these types of cables! No one, not even RUIPRO, suggested that I try a USB power inserter. So I tried the cable with my OPPO BDP-205 UHD disc player and it would not play 4K discs. I made some changes in the OPPO's video menu with resolutions and that solved the issue there. (I did eventually use a USB power inserter with the 4K cable going from my UHD player to the TV with a visible modest improvement in picture quality to my eyes.) I made the decision to go whole hog and buy the RUIPRO 10 meter 8K active hybrid fiber optic HDMI cable. Same excellent construction although the 8K cable was a little thicker than the 4K version. Same problem with resolutions. But then I used the included USB power inserter and everything changed. Now I had all 4 resolutions with the Genie, including1080p and 4K. And I was looking at the most incredibly clear lifelike picture with never before seen nuances of color and shading, especially with flesh tones. I was smitten. Now it is likely that I probably would have had the same experience with the 4K cable had someone recommended the USB power inserter (or if I had just considered buying it myself). I didn't care. I was using the 4k/60 Hz cable with my UHD disc player and now my satellite TV video performance had just gone up off the charts. I have not experienced a single video or audio dropout but it has been only about one month since I installed my cables. Now, this is young technology. I have read reviews where the performance seems to become erratic with time or that the cable just stops working altogether. There are active electronics involved and things can fail with time and need to be replaced. But my version of the RUIPRO 8K cable is a Gen 3 so maybe that portends success and reliability with time. But I am a very happy viewer for now and would recommend the RUIPRO brand without question. Their support is very good and attentive although I fail to see how they did not recommend the use of the USB power inserter right at the beginning of my query. Both active hybrid fiber optic HMDI cables and HDMI over ethernet are pricey ( I spent $175 for my two RUIPRO cables on Amazon. I would have spent nearly $500 dollars for two HDMI over internet systems for my needs.). But if it fits your needs, I would recommend that you try the fiber optic cables. Bear in mind that you need a very good source for your video signal. There is only so much that a good TV and an excellent cable can do with a mediocre source. I have had a very good experience with satellite for 23 years. I wish I could have had a long HDMI cable of such excellence back then!! ... show more

    • Great! But very delicate. Got a replacement within 2 days.
Color: A-8K Fiber Gen3/C Size: 20FT
Just to be clear... a cable that transmits this much data is very hard to do at anything above 12 ft. I have a 20ft and a 50ft version of these cables. Because of how they are constructed to work at those distances, they are incredibly sensitive (any brand, not just this). They don't like being twisted and crammed. I have I have had TWO break on me with normal usage. I'll keep it simple. I use this specifically to output my 4090 to my 120hz OLED TVs. PROS: - Works very well. Maintains full output 4k HDR @ 120hz (even 144hz if u have a C4). - Certified standard... so it means that it's been thoroughly tested. That is what you are paying for. - Customer service was AMAZING. Within 2 days I got a brand new cable. CONS: - VERY delicate. I have these installed in my walls. The necks of the cables do NOT like to be bent or twisted too much. If you plan to plug it in and not really touch it much... then you're fine. Just don't let the neck bend very much. - A pain to re-run cables this long... so that is something you have to be okay with if it dies on you. 100% Recommended IF you don't plan to touch it very much / ensure you aren't bending the neck too much. If you are like me where you switch out the HDMI a bit more often... use strong TAPE to stiffen the neck to prevent it from bending too much. ... show more
