steq184 0 Posted February 14, 2015 I have installed my dvr under the stairs. To connect to my living room tv I am using via/cat5 adaptors. The run is about 10 metres. Anyway when I connected it up using the cat5 i find the screen is all green and pretty dark too. What could be the problem? I am sure the rg45s have been wired properly and don't think the lengthy of run is excessive. Any advice would be great. Share this post Link to post Share on other sites

survtech 0 Posted February 15, 2015 An all green screen usually means that only one color is being transported. VGA-to-CATx adapters just send each individual color (Red, Green and Blue plus Sync) down one pair. See diagram below: If the adapters and cable are wired correctly and you still have the problem, you are probably exceeding the maximum distance of a passive VGA-to-UTP adapter. In that case, you can use a better passive adapter or an active VGA-to-UTP adapter for extended transport. An example is the Muxlab VGA Balun Kit but there are many others. The Muxlab device specifies up to 350 feet (106m) via Cat 5 twisted pair @ 800x600 resolution. Distance will be reduced at higher resolutions. Share this post Link to post Share on other sites
