I wanted to have a small display in my kitchen that showed basic things like my meal plan for the week, weather, etc. I wrote a program to grab the meal plan from the Excel sheet I use to write it down, and the weather from a Weather Underground, and display it nicely. However I didn't want to leave the laptop in the kitchen, I wanted to put it somewhere else to keep the counter looking cleaner.
My house is ethernet wired so I thought of using these. I placed my laptop in a bedroom near an unused ethernet port. I connected one of these to the laptop's VGA port, and the other end to an ethernet cable, which I plugged into the room's ethernet port. Did the same to connect the monitor to the ethernet port in the kitchen. Then in the network box I used a short 3" ethernet cable to connect the bedroom's ethernet port directly to the kitchen's. Voila, I can see the laptop's screen on the monitor!
The only con I have is that the adapter's housing doesn't let it connect cleanly with my laptop. The black tabs that stick out bump into the laptop and don't let it connect. I have to pull the metal connector out of the plastic housing to make it work. The monitor's cable connected to this just fine.
Compared to the high quality 25' VGA cable that I was using, the image is just a hair softer, but comparable given the source material (GIGO). Compared to running a heavy gauge VGA cable in and around an office of other cables and then through a whole in a wall, this is astronomically easier. And if something pinches the cable, which is what happened to my VGA cable leading to a green tinted image, I just cut another patch cable and am back in business.
If you have a low fidelity source that you need to economically send over a reasonable distance, these are the tool for you. Just don't expect miracles. They aren't powered, so won't boost the image down a 100' line, and I highly doubt they'll take a very high resolution.
I'll next be trying to use these over a shorter run for a remote monitor for a server tucked away in a basement.
We have a classroom projector mounted to the ceiling and we use Shielded Twisted Pair Cat 6 ethernet. It's about 50 feet of Ethernet.
We were using an Ethernet to VGA converter box that required electricity. What a pain getting power to that device especially on the ceiling.
In addition to the burden of electricity on both ends the picture quality of that device was horrible. It looked like you were looking at a negative (the contrast was horrible). I put this cheapo device in and with no adjustment it put out a much better picture than the much more expensive box it was replacing. BTW it works fine on resolutions above 1024x768 (1280X1024). I can tell the picture quality is a bit lower than a direct vga plug. Colors are bleeding a little and picture is slightly not as sharp.
Also the screws to hold the vga on are useless on both the pc (dell) and on the projector (Mitsubishi DLP).
