This section explains conditions that you will encounter when operating your MT1020 while displaying an SXGA (128021024) 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.
