Calibrate The Color Wheel - InFocus ScreenPlay 7205 Service Manual

Calibrate the Color Wheel

After you install a color wheel, you must check the color wheel calibration to ensure that colors are
reproduced smoothly on the screen.
To do this, you need the following:
•
Director remote control. This is the remote that ships with the SP7205, and is the only remote that
contains the correct keys to enter the hidden Service menu.
•
The XGA Color Ramp screen, which is available on the SP7205 ASC page
(www.infocus.com/service/sp7205/asc-resources.asp).
1 Connect the projector and computer. Display the computer image. The projector must be five feet
from the projection screen.
2 Open the Color Ramp screen in Microsoft Paint or similar application. Display it full screen.
3 Observe the screen in a dark room. If the three colors do not smoothly progress from black to
color, the color wheel index must be adjusted.
The screen below shows even progression from black to color. This screen does not require
calibration.
If the color ramp you project appears like the one below, no calibration is required. Make sure that
you view the screen in a dark room.
