jimeowen 0 Posted March 3, 2018 Hi guys, I have a strange issue in that my RGB feed gives a pure black screen? The input is 3 x coax feeds (Blue, Green and Red) into an encoder. I have had some success but usually the encoder outputs a pure black screen. There is some talk that the 30M coaxial cables may be just too long for the encoders sensitivity? When I connect a monitor via VGA it works every time! Any suggestions? Thanks Kevin. Share this post Link to post Share on other sites
tomcctv 190 Posted March 3, 2018 Hi. What are you using that still has RGB What encoder are you using and encoding to what at other end Share this post Link to post Share on other sites
jimeowen 0 Posted March 4, 2018 Hi Tom, yes, unfortunately it is an old analogue switch, so I am stuck with RGB. The encoder is a Kramer VP-101 which then goes composite into a Bosch encoder to get an IP output. What do you think about the coaxial cable length, could this be the issue ?
