Hi,
You can find all the info in the product section of BeoWorld. Bascially there are 3 versions: the BV4-50 mkI (EU), type no 897x (resolution 1366x768), followed by the mkII, type no 9039-9049 (resolution 1920x1080) and the current D9/D10 edition called mkIII with type no 905x,908x,907x and 911x). The first one came with the BeoSystem 2, the HD-Ready version with the BeoSystem 2 mkII (w/DVI) and the current is driven by the great BeoSystem 3.
