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.
zYou can turn off auto adjustment (page 46) when you want to disable auto adjustment and maintain manual settings.
zThe projected image may become distorted while an auto adjustment operation is in progress.
zIf 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.
Keystone Correction (AF/AK, KEYSTONE)
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.
