USING THE PROJECTOR
Zoom menu
Use to reduce or magnify an image on the projection screen.
Note:
Zoom settings are retained on power cycle of the projector.
Image Shift menu
Adjust the projected image position horizontally (H) or vertically (V).
Note:
The image size will reduce slightly when adjusting the horizontal and vertical keystone.
Geometric Correction menu
‡ Four Corner: This setting allows the projected image to be adjusted from each corner to make a
square image when the projection surface is not level.
Note:
While adjusting the Four Corner, the Zoom, Aspect Ratio, and Image Shift menus are disabled.
To enable Zoom, Aspect Ratio, and Image Shift, reset the Four Corner settings to the factory
defaults.
‡ H Keystone: Adjust image distortion horizontally and make a squarer image. Horizontal keystone is
used to correct a keystoned image shape in which the left and right borders of the image are unequal
in length. This is intended for use with horizontally on-axis applications.
V Keystone: Adjust image distortion vertically and make a squarer image. Vertical keystone is used to
‡
correct a keystoned image shape in which the top and bottom are slanted to one of the sides. This is
intended when for use with vertically on-axis applications.
‡ Auto Keystone: Automatically adjust image distortion caused by tilting the projector.
‡ 3x3 Warp: Adjust the image distortion by 9 points correction.
‡ Reset: Return the factory default settings for geometric connection.
Note:
When using Enhanced Game Mode, 4 Corner, Horizontal Keystone, Vertical Keystone, and 3x3 warping
will be disabled as the settings impact input lag. If you plan to use Enhanced Game Mode for low input lag,
we strongly recommend setting up the projector without the use for 4 Corner, Horizontal Keystone, Vertical
Keystone, and 3x3 warping.
PureMotion menu
Using sophisticated frame-interpolation technology, PureMotion eliminates motion blurring or image judder, even in
high-speed action sequences. Select between Off, 1, 2, 3 for the varying levels on motion smoothing.
Note:
PureMotion is supported only if the source is HDMI3.
