TROUBLE SHOOTING
71
72
This section explains conditions that you will encounter when operating your MT1020
while displaying an SXGA (1280ן1024) image.
When a menu or message is displayed while an SXGA image is projected, several lines
of information will be lost.
When the "LAMP USAGE 2000 HOURS" message appears, several lines of information
will be lost.
The "LAMP USAGE 2000 HOURS" message will not appear when the freeze button is
activated.
SXGA images inherently display a 5 to 4 ratio, resulting in an image that appears to be
smaller and more square than the 4 to 3 format commonly displayed.
