I have been using a Barco RCVDS 400 Quad with a Data 800 projector. I have two Video/Audio boards, two TTL input boards and four RGB/S boards. I would like to feed the unit a VGA signal. Is there an RGB board the supports seperate sync for the 400? I have found a seller who has such a board for the 800, but I don't know if I can use that or not. If anyone has any experience with this type of setup, I would appreciate the help.
