• Geometry functions adjust geometric distortions of the

display such as its size, keystone, pincushion, bow,

linearity, and skew. Access Geometry functions via

the Geometry menu – press on the keypad.

• 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 slidebar

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) If 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 after each

adjustment to return the cursor back to its previous menu item position.

dark areas of the display image.

To adjust contrast, press then or . If contrast is set too high, the

between foreground and background information.
