[1 (green)] I had tried a number of other brands of HDMI extenders but none of them would work on my long run (150ft). This device works perfectly and the image quality if very good. Several of the other brands introduced green artifacts including the older, 164ft version of the Comprehensive CHE-1. Comprehensive didn't update the model number when going from the 164ft version to latest version which has 70 meters printed on it. If you buy from BH you'll be getting the latest model. Highly recommend this product.

[1] Just works perfect out of the box.

[328' (100 m)] To extend desktop to another monitor in pro environment. Worked right away nonissue and a great solution.

[Metal] Have tried a couple others but mixed results. This one works with everything we plug in. Never worry about it not connecting. We have it at front of church to feed PA booth and another one that feeds projectors. The extra out on the transmitter means we can use signal for a monitor in back as well as big screen in front.
Been a BH customer since the days of magazines. Always my first goto.

[328' (100 m)] I do professional AV installations and have used all Crestron extenders on all my projects previously. Recently I worked with a client on a very tight budget and decided to try this. I was pleasantly surprised at the cost, no issues and synced right up. They use the system every week.

[1 (green)] I have used a number of HDMI over CAT extenders, usually with difficulty. I had my best experience with this one. It worked perfectly the first time I tried it with just one tweak to the skew adjustment. I am using it to duplicate a monitor from a computer and having a HDMI In and a HDMI Out on the transmitter made this very easy. This is going to be my go-to extender in the future. And by the way, the price is also great.

[1 (green)] I use about a dozen of these to send HDMI to various LCD/LED screens and a projector. I've never had any problems with them.

[328' (100 m)] We all have experienced the thrill of finding a great product for a next-to-nothing price. It does happen, about as often as winning the jackpot at the casino.


The truth is, in real life, if you run a business or have a project which just HAS to work without trouble, you're likely to have to spend some money. The trick is not spending more than you need to.


The Comprehensive CHE-1 HDMI Extender is a perfect example of how to do it right. I tried to save money by buying two other brands of less expensive extenders, and, don't get me wrong, they worked. Just not reliably.


I tested the CHE-1 extenders as soon as I received them. They are well packed, have good instructions, and have aced my tests, which are to operate continuously for more than a week in both cold rooms and rooms at normal human temperatures. No black interference lines in the picture. No flickering, a good solid picture on a 100 foot length of Cat 5e cable.

I am glad I bought two of these. I will buy more for future projects. They have earned my trust.

[Metal] I run an AV installation and rental company, and we have used many products like this one over the last few years. I have found the CHE-1 to be a very cost effective way to transport HDMI over long cat5e/6 runs. We have had only 1 failure of the units weve installed, and our records show we have installed 234 of them at the time I'm writing this. That unit was easily swapped out with no issues. The picture quality is excellent, comparable to 2-wire units costing a lot more. HDMI baluns do not always retain the rich color of the source signal, however it has never been an issue with these units. Excellent color, excellent performance. I find this product to be dependable, fairly priced, and of high quality. Specs: 2 input HDMI ports, with a dip switch to select which you want to use. 150 feet max run We recommend using cat6, if possible, with longer runs. Note: Some reviews complain that this unit is not compatible with an ethernet switch, or router. This is true. However, I will make the statement that just because a device uses a Cat5/6 connector (RJ-45) does not mean it is an ethernet device. Many types of technology use the RJ-45 connector and Cat type cables due to their low cost and ease of installation. This is a balun, not a netwrking device. If you want a networkable HDMI device, you need to check out a 100BASE-T compatible video system.
