This seems more complex than I anticipated. I searched TI's website for related application notes but did not find anything.

There is a 50 pin header labeled "video out" on the Spectrum Digital photo of the DM355 DVEVM, is this something that can be wired directly to a 7" TFT 16-bit TTL LCD. I am searching for compatible LCDs as well.
