Epson 7850p Manual De Usuario

In most cases, you can maintain a square or rectangular image by 
placing the projector directly in front of the center of the screen with 
the base of the lens level with the bottom of the screen. 

Even if the projector is slightly tilted (within a range of 40° up or 
down), the projector has an automatic keystone correction function 
that detects and corrects vertical keystone distortion.

It takes about one second after projection starts for the image to be 
corrected. During this time, a vertical keystone correction gauge 
appears on the screen. 

If your image is still distorted, you can correct it using either of these 
methods: 

■

If the image has two parallel sides but is wider on one side (top, 
bottom, left, or right), you can correct it using the 

Keystone

 keys 

on the projector’s control panel or the projector’s Keystone menu 
(see “Using Keystone Correction” on page 27).

■

If the image has no parallel sides, you can adjust its shape using 
Quick Corner

™

You cannot use both keystone correction and Quick Corner at the 
same time.
