Adjusting proportional picture size ( Zoom )
3 4 = Increasing or reducing picture size while retaining the side
ratios
Setting the picture geometry (Geometry)
Calling the Geometry setting window
6 5 = Selecting function
Correcting parallelogram and tilt distortion ( Parallel/Rotation )
Parallelogram distortion means that the sides of the picture bend to
the left or right. Tilt distortion must be set when the screen display is
not axially symmetrical.
3 4 = Reducing the angle of the left and right sides
6 5 = Rotating the picture in a clockwise or counter-clockwise
direction
Correcting pincushion and trapezoid distortion ( Pincushion/Trapezoid )
Trapezoid distortion is when the top or bottom of the screen display
is too wide or too narrow.
3 4 = Bending the right and left side inward or outward
6 5 = Making the bottom edge narrower and the top edge wider
or making the top edge narrower and the bottom edge wider
Correcting unsymmetrical pincushion distortion ( Pinbalance )
Unsymmetrical pin balance is when the sides of the screen displays
are bent inward or outward on one side.
3 4 = Setting the sides so that they are symmetrical
