Vertical
Keystone
Correction
Allows you to manually adjust the keystone settings for the projected image. See Correcting keystone on page 39 for more
details.
Aspect Ratio
There are several options to set the image's aspect ratio depending on your input signal source. Options include:
•
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.
Test Pattern
Displays the test pattern grid, which helps you adjust the image size and focus to check if the projected image is free of
distortion.
High Altitude
Mode
We recommend you use the High Altitude Mode when your environment is between 1500 m - 2000 m above sea level, and
ambient temperature is between 0 ˚ C to 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 to 35 ˚ C. The projector
will be over cooled, if you turn the mode on under such a condition.
