Hi, Thanks for your reply. I'm not sure if I understand this properly as I am pretty new to video work. I don't know if I really mean SVGA I just want to display video that I have resized to 800x600 but the screen I have doesn't display it properly. So I have been given an old PC monitor with BNC connectors on the back for RBG and I want to connect that to the DVEVM. If I do need the SYNC signals can't they be generated by the DVEVM? Thanks, Euan

Hi Euan, I haven't done it for VGA, but I don't think you can create an SVGA signal with just the DACs on-board, as it needs separate HSYNC and VSYNC signals. http://focus.ti.com/lit/an/spraan0/spraan0.pdf describes an add-on board which can modulate an SVGA signal for you, using a THS8200. I have used component (YPbPr) and S-Video by specifying in bootargs: video=davincifb:output=pal:format=component (or replace component with s-video).
