Fixed.
Had to plug in dual monitors (main LCD and the Makvision) which effectively disabled the LCD and enabled the CRT. This took me literally 8 hours to figure out. Still dont know why my Arcade VGA 2 isnt working with it. Probably some similar silly ass windows trick.
For the record, this thing runs very happily in 640x480. Handles 800 and 1024 as well. Cant find any hard specs on it aside from the website (useless) and the crappy manual. Looks great though, very pleased.
