 Correcting Keystone Distortion
When	the	projector	 is	not	 exactly	 perpendicular	 to	the	 screen,	 keystone	 distortion	 occurs.	To	 overcome	 it,	you	 can	 use	
the	“Keystone” 	function,	 a	digital	 technology	 that	can	adjust	 for	keystone-type	 distortion,	resulting	in	a	crisp,	 square	
image.
The	following	 procedure	 explains	how	to	use	 the	[KEYSTONE]	 screen	from	the	menu	 to	correct	 trapezoidal	 distor-
tions.
When	the	projector	is	placed	diagonally...
