- Enable this to be able to choose the drivers for controlling the
- physical display panel/monitor on some platforms. This not only
- covers LCD displays for PDAs but also other types of displays
- such as CRT, TVout etc.
-
- To have support for your specific display panel you will have to
- select the proper drivers which depend on this option.
