We tested the device over 100' of cable with great results. The picture quality appears to be flawless and the fact that it only requires power on one end is definitely plus. Highly recommended!  The small converters on each end are easy to  hide and it was a simple install.

HDMI over Ethernet

startech.com

I was tasked with having users mirror their laptop on a tv (after the built was complete) without software and I have found the answer.  A facility had just finished a renovation and the tv was mounted, power was installed and network drops were in place but no thought had gone into how to utilize the boardroom to its full potential.  After much discussion with endusers and management the most cost effective way would be to use an HDMI extender without any software installation required (since most laptops are locked down these days).  With cables plugged in (HDMI and CAT5/6) all is left for the user to do is to plug in HDMI to their laptop and we now have the laptop screen on the tv.  Another great product from Startech.com.

HDMI over network cable that works!

I often like to show family members videos and pictures of our vacation and the kids from the computer on the TV. We also like to watch a lot of streamed content as well. My TV is not a smart TV so I can't stream content to it from my computer. I often have to copy everything to a USB stick and plug that into my TV. This eliminates that by being able to hook my computer from across the room to my TV as a monitor and watch media content on my TV from my computer without having to move it. Picture is clear without any degradation. The two units are small enough to tuck away out of sight. Did what I needed it to do.

Nice Picture

I got this adapter from Startech to test, and I'm using it now for about 2 months, and it is great. It responds very well and no freezing; it does the job, and I recommend it.

Great product with affordable price

So tested this unit and first thing I will say is the construction quality is great.  Parts seem to be of excellent quality.  Nice that the power adapter has multiple heads for different countries and power supplies.  The brackets included are of excellent quality.
Now trying to set this up was a bit of a challenge for someone who has never attempted.  I was testing over a 50ft cat 5e cable, from my windows pc running windows 10 to a samsung smart tv one floor up.    Now the setup appears easy.   Connect the receiver connect the transmitter, cable in the middle and go...well not so easy...I found I would get a red light on one of the receivers and blue light on the other.   The instructions are not clear really at what to do or what this means so by trial and error I tested.   I switched the source (the computer) to a blu-ray and used the supplied cat5 cable and voila it worked.  great picture etc.   Now I did some research and maybe it was an issue with my cat 5e cable.   they provide some green grounding wires but the instructions do not make it clear as to what we are to do with them.   and the instructions talk about grounded  cat5e cables etc.   As a novice with this..I am not sure if that is my whole issue.   Do I use these grounding cables into a power outlet?  still not sure.
The item itself does work and does display and excellent picture.    Once my cabling issue was solved all seemed to work very well.    I am impress with the quality of the picture and I like the fact that only one power cord is needed as I find too many items need power behind my tv and this made for one less power cord!   Overall it is an excellent product just a few more troubleshooting tips in the user manual and on Startech.com would be helpful

Great build quality, not the best instructions

I have been in the technology business for over 35 years and for the past 20+ years I have been asked to provide unbiased reviews of various products from both the AV and IT world.  In review of this product I have found that it works up to 1920x1080 resolution which is common for TV viewing in 16:9 format, with the accompanying audio  The ease of use was well thought through, simply plug in the source and display and connect over Cat5e and the unit does the rest.  

When testing this unit at 4K Resolution 3840 × 2160 or UHDTV, I noticed a very slight bit of pixelation during fast motion, that distance was at 100'.

My only negative would be that I could not get this product to perform ARC (Audio Return Channel), so I it will not be a solution for a Smart Hub/ Audio Return sound.

In the box:
-HDMI over Cat5e/6 Transmitter
-HDMI over Cat5e/6 Receiver
-Universal Power Adapter (NA/UK/EU)
Mounting Bracket Kit
Cat5e Cable
-Instruction Manual

In summation, solid product, easy to install, set up and use.

HDMI Over Cat 5e/6 Made Easy

Barry

Bought this specifically for my 4k TV which is being connected by the latest onkyo receiver... Connected, and everything perfectly fine for 2 days... For some reason it just shows no signal on my TV now... The lights are blue so the connection should work, but it doesn't. Seems like I wasted 300 bucks on this and got no way to run my ht system

Does not work on my redeliver
