the up and down arrows to adjust the values, then press select to confirm
the changes.
Keystone : adjusts the image vertically and makes a squarer image. You can
also adjust keystone from the keypad. If you want the projector to automat-
ically adjust the keystone, check the Auto Keystone check box. If you then
manually adjust the keystone, Auto Keystone is turned off. When the pro-
jector is in Ceiling Mount mode, Auto Keystone is turned off. You can do a
“one-time” automatic keystone adjustment by pressing both Keystone but-
tons on the keypad at the same time.
Contrast : controls the degree of difference between the lightest and darkest
parts of the picture and changes the amount of black and white in the
image.
Brightness : changes the intensity of the image.
Color : (video and component sources only) adjusts a video image from
black and white to fully saturated color.
Tint : (NTSC video sources only) adjusts the red-green color balance in the
image.
Aspect Ratio : Aspect ratio is the ratio of the image width to image height.
TV screens are usually 1.33:1, also known as 4:3. HDTV and most DVDs are
1.78:1, or 16:9. The default is 4:3, which displays the input resized up or
down to fill the display area.
The aspect ratio selection is saved for each source.
