2.5.2.4.4 Geometry Adjustments 

  The test-pattern diskette uses menus for selecting required test patterns.  The test for mode 4 gives patterns with a resolution of 1024 x 768 pixels (interlaced or non-interlaced, depending on video source).

  All adjustments must be made with brightness control set at center detent and contrast control set at max.  All test patterns should be displayed in mode 4, or in the highest resolution mode supported.

CAUTION !  Only use the plastic end of the adjustment tool for these procedures.  Adjustments for unsupported modes are not required.
