menu are always visible at the
bottom of the display.
To go back to a previous menu
option that is no longer visible,
call up the menu again using

When Test patterns are
selected, the actual colours
displayed may depend on the
settings of the contrast,
brightness and gamma controls.
It may be necessary to set all
brightness controls to 0.0, and
all contrast controls to 1.0,
before making any light level
measurements.
There are two ways of creating

All black test pattern: all pixels
are set to off, but there may be
an extremely small amount of
light leakage through the prism
and DMD assembly.
