Question: Is this the cable that makes Slingbox 350 HD?
Document: I bought this to connect the Slingbox 350 to the Comcast cable box. I really liked the bundled aspect of thesecables since it keeps the wiring neat. The cables were nicely made and I had not problems with theconnections. What else can you desire?
Cables arrived and, unlike many other cables, these are clean and tangle free. Using it with my new Slingbox 350 and it's flawless. Like all Mediabridge products-Highlight recommended.
This 6' component cable was flexible and color coded well to make install easy between my Slingbox unit and HD TV.
Needed an HD-capable cable for use with DirecTV DVR and Slingbox. The cable is perfect. Well-made, has all the connections I needed, and allows for a neat and clean connection.
These cable are awesome. I really appreciate that not only is the jack color coded, but the wire leading up to it is as well - this makes it so much easier when installing because its usually pretty dark behind the TV. These work great for me - they are used between my Roku and my TV and the signal is a crystal clear HD. I would recommend these as the RCA cable to buy here on Amazon, and 12 feet is very long.
Pros:Costworks perfectly (I'm using for a slingbox)came in easy to open boxCons:hasn't help the Red Sox win any better when watching my through the cable onto my slingbox
Nice cable. I love how small it is compared to those huge, flat ribbon cables that were so hard to manage. Bought a Slingbox that had only component connections so bought this one and glad I did. Works great.
Needed a better quality Gold Plated RCA bundle to hook up my slingbox to my cable box. really didn't need 6 feet of cable but it worked out just fine. Great color coding and stout ends. recommend
It is installed and seems to work fine. I bought it to hook up my Belkin Slingbox. Seems to be of a high quality.
it worked great with my smart tv. fast delivery. it was a simple plug and play into my tv and slingbox and all worked well.
Answer: Video component cables carry HD. This is component video AND audio cables. So yes, these cables will carry HD. Just make sure the slingbox 350 supports component video.
