• Multi-scan system
This system distinguishes the horizontal and vertical frequencies of the image
signals from a computer that has been connected and automatically selects the
appropriate system mode.

the horizontal direction, tracking and screen position.

3.4 Mechanisms and Systems
●
Adjustable feet
Adjustable feet have been provided on the front bottom of the main unit on the side of
the projection lens. These feet can be adjusted to set the projector at an incline,
enabling projection at an angle. A maximum angle of elevation of 15.6º can be
established between the projector's optical axis and the table on which the projector
rests.
With one touch, the lock on the adjustable feet can be released and the feet stored
inside the main unit.
* The aforementioned keystone correction function can be used to eliminate
trapezoidal distortion resulting from the projector being at an incline.
