H-V Keystone Function
Correcting Trapezoidal Distortion and
Adjusting Vertical Size of the picture.
This function allows for Keystone correction.
Note
When the image is projected either from top
or from bottom toward the screen at an
angle, the image becomes distorted
trapezoidally.
The function for correcting trapezoidal
distortion is called Keystone Correction.
The Keystone Correction can be adjusted
up to angle of approximately ±15 degrees.
“KEYSTONE” does not work with the 1080I
input signal.

Since the trapezoidal distortion of the image

angle as well.
Straight lines or the edges of images may
appear jagged while adjusting the image.
