Making Detailed Adjustments

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.
