Making Detailed Adjustments 33
Input Brightness Settings
If the signal from connected equipment is weak and images appear dark, you can adjust the
Brightness and Contrast settings. You can adjust brightness and contrast for each image
source and color mode.
The Brightness setting controls how much light is produced by the projector, and the
Contrast setting adjusts the difference between the bright and dark areas of the projected
image. The other settings in this section control how the projector interprets the light and
dark areas of the picture.
■ Brightness
Adjust the brightness so it’s suitable for your viewing conditions. For example, if you’re
projecting in a brightly lit room or onto an especially large screen, you may need to
increase the brightness. Decrease the brightness for dark rooms or small screens.
■ Contrast
This setting adjusts the difference between bright and dark areas.
■ Auto Iris
When this setting is on, the light output is automatically adjusted according to the
brightness of the image. Select either
Normal
or
High Speed
to indicate how quickly
you would like the projector to respond to changes in the brightness of the image. The
setting is stored separately for each image source and color mode.
■ Lens Iris
Lets you adjust the brightness of the image by controlling the amount of light that passes
through the projection lens. You can also access this setting by pressing the
Lens Iris
button on the remote control.
