Blanking Level
This adjusts the blanking from black to white. This
can be used to create a gray side bar for use with 4:3
aspect ratio sources on wideangle screens to help
reduce the chance of image burn-in. Image burn in is
not covered by Faroudja’s warrantee.
Note: The DVP1500 will store unique blanking and
H&V position settings for each aspect ratio which are
automatically stored and recalled when the different
aspect ratios are selected
Patterns Menu
The best approach to system setup is to use a DVD
that offers the proper test patterns. This way, the
system is aligned for the entire signal path. If a test
DVD is not available, then use the internal test
patterns provided in the DVP1500.
Note: The test pattern generator in the DVP1500 is
set to SMPTE standards. To insure proper output
levels for display setup, the picture controls in the
DVP1500 cannot be accessed when the test patterns
are being used. Adjust levels, if needed, in the
display device.
