Using the Gamma Manager Utility
This section covers basic Gamma Manager Utility operation. The Gamma Manager
enables you to adjust the light intensity of screen images by adjusting the display
screen brightness display. Gamma correction is also used to make the projector dis-
play match more closely the image from another monitor or other output device such
as a printer.
Note: Before starting the software, make sure that the projector and the
PC are correctly set up, and ensure that the PC and projector are con-
nected. Refer to “Connecting the Projector to a PC” on page 36.
