Thanks, Why is VGA better for long distances? Is the VGA digital or analogue? I assume RBG is analoge, right? Thanks again for the info. Avin

Hello, I am currently doing a visual display system where video signals (RGB) are to be displayed via projector. The RGB signals from the video is converted to VGA or compiste signal then it is tramsmitted to the projector VIA CAT-6 cable. At the projector it is converted back to RGB. My question is: Why does the RBG need to be converted from RGB to VGA? And why was CAT-6 the choice of cable? Also I noticed in the system there were two devices: UTP video matrix mixer and RJ-45 patch panel - what are the purpose of these devices? I am new to this video display systems and any help would be greatly appreciated. Thanks Yours Respectfully Avin Sinanan
