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.
