Auto Image
Force the projector to reacquire and lock to the input signal. This is useful 
when signal quality is marginal. Normal mode can support all of the 4:3 input 
sources.
Wide mode can support all of the 16:9 input source & most of the 4:3 input

1400 x 1050), perform Auto Image using normal mode.
