Projection Operations

Auto Adjustment of an RGB Image

When the input source is RGB (computer), the projector automatically adjusts vertical and

horizontal positioning, frequency, and phase whenever it detects an RGB signal (following input

source selection, power up, etc.). You can also execute an automatic adjustment operation by

pressing the [AUTO] key.

z You can turn off auto adjustment (page 46) when you want to disable auto adjustment

and maintain manual settings.

z The projected image may become distorted while an auto adjustment operation is in

progress.

z If an image is unclear following the auto adjustment operation, you can use the menu to

adjust items manually. For details, see “Image Adjustment” on page 31.

When the projector is at an angle to the screen it is projecting on, the projected image may

have different length left and right edges, or top and bottom edges. This phenomenon is

called, “keystoning”. This projector comes with functions for automatic as well as manual

keystone correction, which provides a regularly shaped projected image. The following shows

the allowable angle that the projector can be positioned relative to the screen.
