Screen Capture
Use this function to customize the startup screen. To capture
the image that you want to use as the startup screen, follow
the instructions below.
Notice
Before proceeding with the following steps, make sure that
the "Keystone" is set to the default value "0" and the
projector is in its native resolution.
• Select "Screen Capture" to customize the startup screen.
• A dialog box appears to confirm the action. Choose
"Yes" to use the current image as your customized
startup screen. Choose "No" to cancel the screen capture
and exist the Onscreen Display (OSD).
• A message appears stating that the screen capture is in
progress.
• When the screen capture is finished, the message
disappears and the original display is shown.
Source Selection
• Manual: When switching input signals, you need to press
"SOURCE" on the control panel or remote control, or
the direct source key on the remote control.
• Auto: The projector will detect your source
automatically.
Closed Caption
Selects a preferred closed captioning mode from CC1, CC2,
CC3, CC4 (CC1 displays captions in the primary language in
your area). Select "Off" to turn off the captioning feature.
This function is only available when a composite video or S-
Video input signal is selected and its system format is NTSC.
DC 5V Out
Selecting "On" enables the function. The MHL port(s) and the
DC 5V out port/USB A port (if available) on the projector can
output 5V power when the projector is turned on.
Only MHL port(s) will provide power output when
MHL port(s) and USB A port are both plugged.
VGA OUT
(Standby)
Selecting "On" enables the function. The projector can
output a VGA signal when it is in standby mode and the VGA
IN (or VGA IN 1) and VGA OUT sockets are correctly
connected to the devices.
Enabling this function increases the standby power
consumption.
HDMI CEC
Selecting "On" allows synchronized power ON/OFF operation
between the projector and a CEC-compatible device
connected to the HDMI/MHL port of the projector.
This function is only available for the HDMI/MHL port.
