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 avail- able, then use the internal test patterns provided in this unit.
●The test pattern generator in this unit is set to SMPTE stan- dards. To insure proper output levels for display setup, the picture controls in this unit cannot be accessed when the test patterns are being used. Adjust levels, if needed, in the display device.
