Q2. Do I have to use a Panasonic wall bracket, or can I use other 3rd party wall mounts?

Answer:

We recommend you use the optional mounting brackets manufactured by Panasonic.
However, if you choose to use another brand of wall bracket, please be sure it will accommodate the position of the mounting bolt holes on the Panasonic Plasma TV (660mm x 320mm pattern), the thread of the screws (M8 type), and support the weight of the display (consult the Operating Instruction manual for your model).
