Viewing Lamp Usage and Other Information
Use the Info menu to view information about the display settings of
your computer and the number of hours the lamp has been used.
Press the
Menu
button and highlight the
Info
menu.
You see the lamp usage hours and various input signal settings on the
right.
The life span of the lamp is about 2000 hours if the
Brightness
Control
setting in the Setting menu is set to
High
(default), and
3000 hours if the

. Make
sure you have a spare lamp handy if the usage hours on this menu
are close to the life span of your lamp.
