What is keystone correction?

What is keystone correction? A projector is a two-piece system: a projector and a screen. All projectors use rectangular imaging chips to create an image, and it’s crucial that the image sent by the chip is exactly perpendicular to the screen.

We will cover these topics:

• What is the keystone correction?
• What can be done other than using keystone?
• The Bottom Line

What is Keystone?

Keystone correction allows projectors that are not positioned perpendicular to the screen to skew the output image, making it rectangular. The vertical keystone corrects distortion at the top or bottom of the image, while the horizontal keystone corrects distortion on the left or right.

What else can I do other than use keystone?

The correction allows projectors that are not positioned perpendicular to the screen to skew the output image, making it rectangular. The vertical keystone corrects distortion at the top or bottom of the image, while the horizontal keystone corrects distortion on the left or right.

The bottom line

With automatic correction, the projector will automatically detect the distorted image and correct it for the correct output at the touch of a button. It is easy to use and can project images of the appropriate image size.
