Section 3: Operation

The Func+Help key combination will immediately disable the Keystone, Brightness Uniformity, Edge

Blending and Black Level Blending features. This is helpful when, in some extreme keystone configurations,

some image corruption may appear and/or the menus may not be readable. Although Func+Help disables

these features, it will not overwrite their settings. If keystone is simply enabled again, the same image

corruption may occur. After pressing Func+Help, it is recommend to immediately “Reset Keystone Settings”,

which will set all keystone co-ordinates to zero.

3.3.3 Brightness Uniformity

Brightness Uniformity provides further refinement of displays already matched for their primary colors and

overall light output. Use the Brightness Uniformity menu options for basic adjustments so that no area

appears brighter than another. In the Brightness Uniformity menu, enable the Brightness Uniformity Enable

check box to access a multitude of adjustments for light output control in specific areas throughout the image.

Your settings apply as long as the Brightness Uniformity Enable check box is enabled. While making

adjustments, enable the Coarse Adjustment check box to apply Brightness Uniformity settings with a large

granularity. Coarse Adjustment helps identify brightness changes and accelerates projector response time

while adjusting settings. To disable the Brightness Uniformity function, delete the Brightness Uniformity

Enable checkmark.

To correct brightness uniformity for a complex screen setup, see the TWIST User Manual included in the user

kit.

What is Brightness Uniformity?

When used to refine screens already matched for their primary colors (see 3.5 Using Multiple Projectors) and

overall light output, proper adjustment of Brightness Uniformity can create an exceptionally smooth screen in

which:

• No area of the screen appears brighter than another

• Light output from one screen closely matches adjacent screens

Although the Brightness Uniformity control can be used for a stand-alone projector, it is particularly useful

for setting up and maintaining tiled images that form a cohesive display wall in which the color “cast” and light

output appear uniform throughout each image as well as throughout the entire wall. The procedure provided

here assumes a multiple-screen application.

IMPORTANT! Before You Begin

Read through the entire procedure before attempting to adjust Brightness Uniformity controls.

Adjusting Brightness uniformity

1. Adjust the primary colors as described in 3.5 Using Multiple Projectors, before attempting to work with

Brightness Uniformity. This ensures that primary colors, color temperature, and maximized light output

are all well matched from one screen to another. These matches are needed before you can achieve good

brightness uniformity results.

IMPORTANT! Double-check that all WHITES and LIGHT OUTPUT are well-matched.

2. Enable the Brightness Uniformity check box. This will enable access to the uniformity controls and will

apply the settings to your image.
