OPERATION
Convergence is used to align the red, green, and blue color components of the image. It is
described in section 3.6,
Convergence Registration.
Most adjustment functions, when selected, display a slidebar overlayed on the source
image. The sliders displays the current setting and indicates which arrow keys to use for
making the adjustment. Adjustment settings are stored in the current setup memory (input
or Recall). There are two exceptions: 1) lf the current setup memory is locked, new
adjustment settings are shown but not stored; they are discarded when another setup
memory is selected. 2) If ASR
is on for the current input and an ASI is performed, the
settings are only temporary and are not saved in the current setup memory.
For new images, where much adjustment is required, it is recommended that adjustments
be made using the sequence illustrated above. When making picture or geometry
adjustments, follow the sequence displayed in the adjustment menu.
Tip: When making many picture or geometry adjustments, press ENTER after each adjustment to return
the Cursor back to its previous menu item position.
Primary Display Adjustments >
Brightness
The Brightness function is used to adjust the black level of the image.
To adjust brightness, press BRITE then UP or DOWN . If video or data is
displayed with a black background, adjust until the background just disappears (black
becomes a very dark grey).
Note: If room lighting changes, it may be necessary to re-adjust brightness.
Contrast
The Contrast function is used to adjust the contrast between the light and dark areas of
the display image.
To adjust contrast, press CONT then UP or DOWN. If contrast is set too
high, the image loses detail and clarity. lf set too low, it may be difficult to distinguish
between foreground and background information.
Notes.. 1) For best results, adjust
brightness before contrast. 2) If room lighting changes, it may be necessary to re-adjust
contrast and brightness. 3) An excessively high contrast level can reduce the life of the
CRTs.
Detail
The Detail function is used to adjust the picture sharpness of video signals when using
the optional Multi-standard Decoder.
