Projection Operations
Zoom and Focus
Use the zoom ring to adjust the image size, and the focus ring to focus the image.
z It is best to have a still image on the screen when you focus the image.
z Performing zoom after focusing can cause the image to go out of focus. If this happens,
focus again.
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 41) 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 “Signal Settings” on page 30.
