Whilst cruising ebay for LCDs for Taco CCs and other hacks, I found a seller offering cheap controller boards to drive bare LCD panels from a range of inputs - VGA, DVI, HDMI, s-video and composite video, depending on model and price. They claim to be able to drive any LCD as long as you have the specs/data for the panel, and even offer programmable boards - ranging from boards with DIP switches/jumpers for a preset range of panels, to fully end-user programmable boards, and programming devices to suit.
