After hooking everything up, the screen flickers and it does not give a proper signal from my projector to my AV receiver

I tried said "no signal", and the other TV I tried acted like it was getting a signal, but just displayed a thin green line along the top.

Did not provide enough signal strength .

Then, next black screen, lose signal

Once the all-black screen was filled with a picture (or something of color) it would find the signal again and everything would work.

Ran a full HD signal out of my laptop through these extenders along a 100ft. run into an HD projector and the signal is perfect.

Constant dropping of the signal, flashing screen, pix-elated video quality, and just overall reliability forced me to return these

Static signal

They have a great durable casing, great signal

no signal distortion at the monitor

If you are having problems with this device the first thing to look at would be the cables you are using, you cannot use older CAT5 cables with this, you need at least a CAT6 cable to get a good signal.
