It is not the D9 or the D10.
If you are based in Europe, the resolution changed from 852 x 480 pixels to 1024 x 768 pixels from serial number 18390228. Also, you need the BeoSystem 2 mkII to take advantage of the HD-Ready features of the display.
If you have the US/CND display (type no 8956) then the resolution is 1024 x 768.
All information based on the fact that this is the 42" panel.
