Used this cable with no transmission issues at all from a Directv HR21 HD-DVR 20 feet over HDMI to a Monoprice 1x8 distribution amplifier then 100 feet over this cable to a Fujitsu Plasma Display. Yes, you should always test on the floor before you install, but this cable did work perfectly for me.

Bought this 100ft HDMI cable for less than $100. Couldn't even find one for 3 times the price at the big stores. They also said 100 feet is too long to carry a HD signal.
They were wrong as this worked from the minute it was plugged in even thru a 4x4 HDMI multiplexer (also a great buy). Thanks Monoprice for saving me $500 at least since one of the workers installing the system drilled a large screw through the first one I had bought.

The cable I received from Monoprice was great. It was a 100' cable that my husband strung from the house to the shop. I would definitely buy more products from Monoprice.

PROS: Wide variety of cable sizes here at Monoprice.


CONS: None.

Excellent

I read through the various reviews for this cable before making the purchase and agree with most about the bend radius. Fortunately, I was installing the cable in new construction and didn't have any terrible issues. Having said that, I also read where others had mentioned an in-line equalizer and did not see any markings or other indicating that there was one, or what end of the cable it was on. Having said that, I delayed the installation of the cable a day, and connected it to AV gear to test. I found that the cable worked the same installed in either direction without issue.

For HDMI runs this length, I'd recommend this cable because I know it works. However, the bend radius, or lack of, makes it a bit tough to install.

PROS: Works as advertised

CONS: Cable thickness
Bend radius

came in the next day, just as needed. very sturdy looking and was able to run it across my showroom for an event this weekend. monoprice ftw!

Purchased cable to run from HR21 DirecTV Receiver to television on the other side of the house (didnt want to pay for the extra cost of another HD receiver & the added monthly receiver fee from DirecTV).

Picture & sound come through flawlessly & with DirecTVs built in RF-remote control feature, all I had to do was pick up an extra RF remote off of eBay for less than $10 to control the receiver on the other side of my house.

Also before installing decided to test on my DirecTV HR20 HD DVR to see if this long-run cable would work on older generation boxes & it worked great!

No noticeable picture or sound degradation on either boxes to both my Panasonic TH-42PZ80U 1080p Plasma or Hannspree XV 32 LCD.

One note though...this cable is THICK. Went to Home Depot & had to purchase 1/2 inch plastic cable clamps (Gardner Bender Part #PPC-1550) to secure cables to inside of walls. Decided on these because they had very little chance of damaging this HDMI cable since the nail/screw used to secure these clamps were off to the side, rather than directly requiring hammering directly above the cable to mount. Also, because of the thickness of this cable, I couldnt use Wiremolds single cable run solution & had to move up to the 3 cable run cable management series, even though this was a single cable.

Also, to minimize stress on DirecTV Receivers HDMI port, used Monoprices p/n 2891 -
HDMI Cable male to female 28AWG Port Saver - 8 inches (Gold Plated Connectors). Again, picture still came through perfectly.

I originally purchased the Monoprices p/n 2672 - 100FT 5-RCA Component Video/Audio 20AWG Coax Cable (RG-59/U), but after testing on my DirecTV HR20 DVR, I discovered that the cable carrying the Red signal was defective & the connectors werent all that secure. Although they were half the price of the HDMI cable, after seeing this Component cable in person, decided to pay double the price for the HDMI cable for a pure digital signal, but more important, to reduce the number of cables from 5 (Component x3 Audio x2) to the simplicity of a single HDMI cable for vidio & audio.

Works great.

I had fretted over upgrading the component signal to HDMI for my projector for several years. However, I needed at least 80' of cable and knew I might have signal problems. MonoPrice offered a 100' cable at a great price and it could be returned without a restocking fee. Knowing that professional installers cringe at the thought of long HDMI runs, I decided to try my luck and test it first. It work flawlessy between my OPPO player and high end Sony projecter during the test and I called in a pro to assist for the in-wall installation. Things went smoothly, but the weight of the cable tended to pull the connector from the socket when I moved my rack. I wanted direct connections since fewer connections meant fewer chances for problems. Strapping everything tightly near the connectors has thus far solved the problem. The pro said I am quite lucky to have this working well since they have used cables costing $300 without success. The HDMI signal is noticeably superior with my gear.

PROS: Worked perfectly.

CONS: Quite heavy and connecting directly to components is a bit tricky, especially if you direct connect to a Blu-ray player on a movable rack.

Was banking on this really long HDMI cable for a church project. But had heard mixed stories about HDMI at this length. This cable performs perfectly using an HDMI matrix that supports cable lengths up to ~100'.

Cable is quite thick which brings pros and cons. Pros: it works at 100'. Cons: difficult to work with as it does not want to twist nor bend. And in my case it eats up a big portion of the available conduit space.

But all in all I'd give it an A+.
