A friend of mine has a Hitachi GMK-29FS3. Looks to be a fairly common monitor in Neo candy cabs (which is what this is in). Looks to be switchable medium/standard res, currently set to standard. Want to confirm the procedure.
Looks like just moving the one connector is all that is implied, but without a manual I wanted to ask those who know more about monitors than I. Unfortunately, most of the labeling is in Japanese (and abbreviations, too), and I don't have a wiring diagram.
