test patterns
The DVD32R is the world’s first DVD player with an in-built test pattern
generator to assist you in adjusting your picture, PAL or NTSC, for best
performance.
Many display devices are wrongly adjusted when leaving the factory
because they need to overcome the bright lighting in the show rooms
from which they are usually selected. However, once installed at
home, the viewing conditions vary considerably from those in the
show rooms, hence display devices need re-calibrating.
Most important for a perfect picture is the absence of surrounding light
in the room, particularly light which can hit the screen. An often
suggested low brightness light, placed behind the screen (hence
preventing it from reflecting in the screen) should only be used if you
want to watch tv leisurely for a long period of time. For best movie
presentation, keep the surrounding light intensity as low as possible.
It is not just the absence of surrounding light which can improve the
performance of your display device, it is also the colour of the walls,
as these will also reflect light, emitted (or reflected, when using a front
projector) from your screen, ‘bouncing’ it back on to the screen to
‘wash-out’ the picture. The perfect home cinema would be pitch black
with no added light in the room! Not the most pleasant of rooms, but
highly effective. The result would be great picture quality, assuming the
display device is up to the task and adjusted properly. A more
practical solution is walls painted in darker colours without a reflective
surface.
