 Note:
● Either "H/V Keystone" or "Corner correction" setting value is valid. When the "H/V Keystone" or
"Corner correction" adjustment is finished, the adjusted value will be reset when you adjust the
other one.
● Press the KEYSTONE button on the remote control or side control when the "H/V Keystone" or
"Corner correction" screen is displaying, it will switch to the other adjustment screen.
● When the "Corner correction" individual adjustment screen is displaying, the individual
adjustment screen of the next corner can also be displayed by pressing the <ENTER> button.
● Correcting up to ±15° for the tilt in the vertical direction and ±15° for the tilt in the horizontal
direction are available for adjustments with "Keystone". However, the image quality will degrade
and it will get harder to focus with more correction. Install the projector so that the correction will
be as small as possible.
● Screen size will also change when "H/V Keystone" is used to perform various adjustments.
● Aspect ratio of the image size may shift depending on the correction.
