OSD Menu description
Brightness
Use to adjust the brightness of the projected image. You can connect the projector to an external
image source to display an image resembling the one shown (PLUGE, Picture Line-Up Generation
Equipment) for adjustment. Although there are numerous versions of PLUGE image, they are typically
comprised of blocks of black, white and gray on top of a black background.
It is recommended that you adjust the image to the
following status:
• The darkest black bar of the image should disappear
into the background.
• The dark gray area should be barely visible.
• The light gray area should be clearly visible.
• The white area should appear real and mellow.
• The image should only display black, gray and white
(with no other colors).
Contrast, Brightness, Saturation and Tint are interrelated options that affect
one another; when you adjust one of them, you might have to fine tune other
settings to get the best projection results.
The following image illustrates the results of direct brightness adjustment using a random image:
