As far as I remember, there might be a B&O specific software and/or service menu settings necessary for the pana pro display to work. Especially autocontrast, power on/off etc.
I used a pana th-42pw6 series display with a beosystem 2 (had to change some service menu entries).
So, unless you find the info here (?) or your dealer is willing to help...., there might not be a solution.
Keep us informed!
