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.
