test patterns
pluge 2
The cross hatch included in the DVD32FLR is
a multi-purpose test-pattern which will allow
adjustment of contrast and sharpness.
Cross-check your setting by turning back to
the PLUGE 2 test-pattern and check that the
bright white field (PLUGE 2) isn't blurred
into the black background. Some display
devices allow a very high contrast setting
without blurring, others will always blur.
On some display devices the black lines
will have a second or even multiple lines
beside them, usually shown in a light grey.
They can be caused by many reasons, for
example poor cables between the DVD
player and the display device or - usually
only available in NTSC - a wrongly
adjusted sharpness control. Use good
cables, such as our S-Video or digital cable
(for Composite or Component) and turn the
sharpness right down to remove these
artifacts. Frequently you might find that you
cannot remove those extra lines completely.

The test pattern includes a series of black
lines on a white background. Adjust the
contrast, after having set the black level
correctly, so that white becomes solid
without blurring into the black lines and
without turning the black lines grey.
colour
The colour test-pattern allows you to adjust Colour (and Tint in NTSC)
(1)
. Adjust those two
parameters until yellow looks yellow (without including too much red) and Red is not over-
saturated. Your might use filters, available from specialist suppliers, which will allow you to
more objectively adjust colour.
