I needed an HDMI cable for a 50' run from receiver to projector. Based upon my previous experience with approximately a 40' run and the comments on this site, I felt I needed a boosted cable. This cable worked perfectly the first time it was hooked up, and has continued to do so. Be aware, however, that this is not a thin cable. It is 1/4" in diameter and although it is reasonably flexible, speaker wire it ain't. I was just able to squeeze it and the projector's power cable into a half-round plastic cord raceway. Fortunately, there appear to be no ill effects from pairing the two cables..
Died after 4 years. Now stuck with dead cable in ceiling
Installed to connect a projector. It worked fine for 4 years and then died. I didn't anticipate cable failure in my installation. Although the product has a warranty, Monoprice requires the entire product to be returned. Since it threads through about 8 joists and then bends down into the wall, it is impossible to remove so warrnty is useless.
I needed aq run from my main panel, Monoprices 8x8 4k matrix switch, to a Yamaha 4k receiver. It worked ok in a test where I used 3x15 foot 18gbs cables to see if it would work. It worked fine so I bought this cable. The Yamaha sees no sound, just picture, for about 10 minutes while it "warms up". After that it worked fine but it took ten minutes of no sound, sound, no sound, sound, many times before it stays on. It worked with other cable, so there must be a short coming with this cable. I swapped receivers around and a Denon works fine with the cable, and the Yamaha works fine using another cable not quite so long. Not recommended for 4k 7.1+ sound reliably. It could just be my sensitive Yamaha. But other cables work fine with it.
Seems to be working .....had the other heavy duty ones but had picture drop outs. I have 40 foot run to AVR and back. Wasted 75 bucks on the other ones I guess should have just got the active ones. I don't think you should sell the other 40 foot ones if they are not going to work, Maybe limit those to 30 feet.
The cable was well packaged and shipped very quickly. After I installed it, there was a notable improvement in the picture quality. This was to replace a damaged HDMI cable. This is a much higher quality than the previous name brand, higher priced cable. The brand was recommended to me by a video conferencing technician. I'm glad I followed his advice and purchased this cable!
