Keystone Correction
When the projector is placed at an angle to the screen the image can appear as a trapezium shape, rather than a rectangle. LV projectors counter this effect – known as ‘keystone distortion’ – with a function known as Keystone Correction. In selected models a tilt sensor detects the projector’s angle of tilt (+/- 30 degrees) and automatically alters the image on the LCD panels to achieve a perfectly rectangular image. In all models the keystone can also be corrected manually.
