Runco Video Xtreme VX-40d Owner's Operating Manual page 61

In the Configuration menu, select
the Geometry and Color submenu
when you need to modify overall
color performance and/or image
geometry for all sources.
Test Pattern
Choose the desired internal test pattern or select OFF to turn off a test pattern. Alternatively,
use the Test key for cycling through test patterns.
Vertical Keystone
Use to correct a keystoned image shape in which both sides of your image are inclined
toward the top or bottom edge. Keystone is typically caused by tilting the projector in
relation to the screen, so that the lens surface and screen are no longer parallel to each
other.
NOTE: Runco recommends that the keystone feature not be used unless absolutely
necessary, as it may cause some artifacting in the image.
Brightness Uniformity — SUBMENU
Brightness Uniformity provides further refinement of displays already matched for
their primary colors and overall light output. Use Brightness Uniformity to create an
exceptionally smooth image in which no area appears brighter and/or more red, green
or blue than another. In the Brightness Uniformity menu, enable the "Uniformity Enable"
checkbox (enter a checkmark) to access a multitude of adjustments for critical color light
output control in specific areas throughout the image. Your settings apply as long as the
"Uniformity Enable" checkbox is enabled and you are using a "User" color temperature
defined by the Brightness Uniformity controls. Remove the checkmark from the "Uniformity
Enable" checkbox to disable the Brightness Uniformity function.
