Aspect Ratio There are several options to set the image's aspect ratio depending on your input signal source. • Auto: Scales an image proportionally to fit the projector's native resolution in its horizontal or vertical width. 15:9 picture • Real: Projects an image as its original resolution and resizes it to fit within the display area. For input signals with lower resolutions, the projected image will be 4:3 picture displayed in its original size. 16:9 picture • 4:3: Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. • 16:9: Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio. 4:3 picture • 2.4:1: Scales an image so that it is displayed in the center of the screen with a 2.4:1 aspect ratio. 16:9 picture 16:9 picture 12V Trigger If On is selected, the projector will send electronic signal out when it is turned on. We recommend you use the High Altitude Mode when your environment is between 1500 m -3000 m above sea level, and ambient temperature is between 0°C-30°C.

Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under such a condition. SYSTEM SETUP: BASIC menu Language Sets the language for the On-Screen Display (OSD) menus.

Auto
: Scales an image proportionally to fit the
projector's native resolution in its horizontal or vertical
width.
•
Real
: Projects an image as its original resolution and
resizes it to fit within the display area. For input signals
with lower resolutions, the projected image will be
displayed in its original size.
•
4:3
: Scales an image so that it is displayed in the center
of the screen with a 4:3 aspect ratio.
•
16:9
: Scales an image so that it is displayed in the
center of the screen with a 16:9 aspect ratio.
•
2.4:1
: Scales an image so that it is displayed in the
center of the screen with a 2.4:1 aspect ratio.
12V Trigger
If
On
is selected, the projector will send electronic signal out when it is turned on.
High Altitude
Mode
We recommend you use the
High Altitude Mode
when your environment is
between 1500 m –3000 m above sea level, and ambient temperature is between
0°C–30°C.
Operation under "
High Altitude Mode
" may cause a higher decibel operating
noise level because of increased fan speed necessary to improve overall system
cooling and performance.
If you use this projector under other extreme conditions excluding the above, it
may display auto shut-down symptoms, which is designed to protect your projector
from over-heating. In cases like this, you should switch to High Altitude mode to
solve these symptoms. However, this is not to state that this projector can operate
under any and all harsh or extreme conditions.
Do not use the
High Altitude Mode
if your altitude is between 0 m and 1500 m and ambient
temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on
under such a condition.
