Epson 7850p User Manual

Even if you don’t have a screen, you can project images onto surfaces 
like blackboards and colored walls without loss of image color. Your 
projector has a sensor that measures the conditions of the projection 
surface and automatically adjusts the colors and shading of your 
image. For example, if you’re projecting onto a surface near a window, 
your image appears clear and well-defined rather than faint.

Press the 

Wall Shot

 button on either the remote control or the 

projector’s control panel while projecting an image. 

Wall Shot’s status appears in the upper right corner of your screen. 
Then you see a sequence of colors flash for approximately five seconds 
while the sensor measures the conditions of the projection surface and 
adjusts the image.

When you turn the projector off, the projector stores the correction 
values obtained by the last Wall Shot measurements. This is useful if 
you’re projecting against the same surface and under the same 
conditions. To retrieve these corrections, just press the 

Wall Shot

 

button again while projecting an image.
