We've been struggling through the installation of a Barco 1209s. We've resolved a number of problems; our latest is that the image 'floats' - kind of like a screen saver effect, moving generally in a diagonal line till it hits the edge of the projection area, then bouncing off and moving in a new direction. I originally thought there was too much noise in the signal, since I was driving it from a computer 8+ meters away, but using a 1 meter cable does the same thing, using S-video or 15HD->5BNC. Any ideas for things to check? Things to fix just on general principle? Thanks in advance, Harry.
