I am designing projections for a production this fall that will use rear projection onto the cyc for backgrounds. Ideally, our projection operator will be in the booth with lights and sound, rather than behind the cyc where they can't see what is happening. To make this possible and avoid signal degradation over this long distance, I am looking at running the video signal over Cat5 cable. I have a Cat5 cable that will be long enough, and I found several adapters like this one online, but I also found adapters that are more expensive and look more complex (like this). Should I take this to mean that, if I use a cheap, simple, adapter, it will not transmit the signal correctly? And if so, is there a way I can make a simple adapter work correctly rather than having to buy an expensive adapter?
