Silverback S6 4k HDMI Cable 25 ft - HDMI 2.0, HDCP 2.2 and 3D Support, 4k @ 60hz 4:4:4, Deep Color, by Sewell

Update 12/18/16 - Well, the replacement cable stopped working two days ago. At first I thought it was the KINIVO device but after swapping out the HDMI Cable it became clear it was the Sewell Cable that failed - AGAIN. I swapped it back multiple times to be sure.Update 10/7/16 - Sewell sent a replacement cable and it indeed works. So, three stars. Can't do more than three given the hassle, etc... They've asked me to send back the non-working cable and provided return label - so fair enough.Impressed and appreciative of the excellent and responsive customer service. Let's see if the cable works over time.---- Previous 1 Star Review:DOA - didn't work

I'd gotten a new 4K TV and had to upgrade my HDMI cables, so I purchased this Sewell Silverback cable. I'd actually purchased three (this 20' one and two 3' ones for other components). After two weeks of troubleshooting why my new TV's video feed would cut out periodically, I finally swapped out this HDMI cable for a Monoprice one of the same length and resolved the issue.When I had first received these cables, I also wasn't very happy with the build quality. They look much more robust in the pictures. The tough-looking connectors are actually cheap plastic that fit loosely, and the mesh that surrounds the cord itself just seems like simple plastic.So far, the other two 3' cables are working fine that I'm using to connect an Apple TV and a blu ray player to my AVR, and a regular 1080p HDMI cable that I'd owned previously for two years also served me well. But I'll definitely never purchase another Sewell product after the headache this one caused me. I'm not sure if it's a problem with the HDCP 2.2 compliance in this 20' cable or not, but this Sewell Silverback cable should definitely be avoided over the competition.For almost half the money, my Monoprice replacement, while ugly as h***, feels much more robust and has given me zero issue.

The cable is a bit stiff, but that can't be helped (I purchased the 25 foot length and a 3ft). I mention this in case you don't have a lot of space behind the TV etc.I am happy to report the cable passed full 4K and UHD signal transmission at 25FT with a Roku Ultra and Denon X6300. Initially it did pass HDCP compliance, but it was actually something in the Denon causing the issue. I connected the ultra directly yo the tv using the 25ft cable and everything passed both the Roku and TV signal checks. I then reconnected the Denon with the 3ft cable and everything checked out. I have tested it with UHD streams from Amazon and regular 4K from Netflix with no issues. I was originally concerned I might need a HDMI booster but this cable worked great at a great price.

Works as advertised, at first bought it,thought I was going to get 4k 60 fps 60 hz since it was the newer 2.0,but screen kept on saying 30 fps 30 hz. The wording when I bought this was a bit unclear,in the end to get 4k 60 fps to use from my computer..needed a display port to hdmi, then enable enhanced hdmi on TV use it on a port that says 60 hz 4k,you will be very happy. If you want to save money, simply look for any hdmi cable that does 18 gbs a second, that's the same as 4k,but selling it as 4k is a slight gimmick because all 18 gbs hdmi are 4k capable. So I took off one star for that and them not really telling you if you want TRUE 4k from computer to TV you need the display port. Otherwise decent and we'll made cable.

Cable is very stiff. It torques the HDMI port on my TV. It has a tendency to come loose and disrupt the connection. I have found the Securian cables to be much more flexible and they also provide 2.2 protection.Update: 03/20/17The Securian cable that I used to connect my Roku Ultra to my LG OLED tv does not have a stable HDCP 2.2 capability. I had to re-use my Sewell cable because it is the only true HDCP 2.2 cable I own that will connect my Roku. It works fine now. The trick is to insert one end of it into the HDMI port on your TV FIRST! Then insert the other end into your device. That way the end into your TV will not get torqued. I retract my two star rating and resubmit a five star rating.

Surprisingly It works for me over 30 feet 4k@ 60 chroma 4:4:4 , I have to admit I was a little hesitant, but It actually works for meDevicesSamsung UN65KS8500 connected to ASUS GeForce GTX 1060 6GB ROG STRIX OC Edition**this is the second one I ordered and it works as well with no problem the first one though had the braided part damaged I guess in manufacturing process, to me that simply signifies inadequate QC! btw it comes pretty much in a plastic bag not packaging lucky they included the caps :) had it not been for these I would have been very impressed and a Five star !!!

Seems built well. Improved my picture considerably over an old HDMI cable I was using. Helped quite a bit to cut down on my Roku freezing and rebooting due to the signal on the old HDMI signal.

Appeared to be a sturdy, well-made cable which accounts for the two stars, but it did not work as advertised. Even at 30' it did not pass 4k60hz on my system. I was hopeful, but not surprised as this is apparently a very difficult task for an HDMI cable. I returned it.
