I am setting up my projector on back side of the room mounted to the ceiling, with the rest of my equipment at the front of the room under the projected image. I bought a 50ft and 25ft component cable, both gave me a greenish decoloration rolling up the screen because of the long cable run/not-so-great quality cable I assume. But I still need a high quality component cable that is at least 40ft long, and won't have the common negative side effect of long cable runs. Can someone point me out the a good set of cables that will not have this problem?
