• The picture quality may deteriorate when the V Keystone function is used, because it is an
electrical correction.
• If you set "High Altitude Mode" to "On" at an altitude of under 1,500 m, the reliability of the lamp

• The auto V Keystone adjustment may not correct the trapezoidal distortion perfectly, depending
on the room temperature or the screen angle.
