Description of Adjustment Items
Auto Sync Adjustment
Used to automatically adjust the RGB input signals when
turning on the projector to achieve optimum images.
• When “AUTO SYNC” is set to “ON”, adjustments to the computer set-
tings are automatically made when the projector is turned on or when
the COMPUTER/RGB mode is changed.
• When “AUTO SYNC” is set to “OFF”, automatic adjustments can be
made by pressing AUTO SYNC on the projector or the remote control.
During Auto Sync Adjustment, the On-screen Display on the left
appears.
• Auto Sync Adjustment may take some time to complete depending on
the image of the computer connected to the projector.
• To display a blue screen (in place of the Auto Sync Adjustment screen),
see “Auto Sync Display Function (RGB mode only)” on page 20.
