Why can't I see all text and people on the screen?

You might have turned on a setting that is zooming in on the screen. I pulled this from a Mitsubishi site that might have directions needed to fix this:

Turn on your Mitsubishi rear-projection TV. Press the "Input" button on the remote control to select a particular video source, such as the cable/satellite set-top receiver box/DVR or DVD player.

Press the "Format" button on either the remote control or the front panel of the unit to adjust the picture size. Choices include "Standard", "Stretch", "Expand", and (with CRT models) "HD expand." Keep pressing until you find the optimal picture setting for that source. The last setting you choose will be saved and the picture will be displayed in that manner the next time you view that source.

Repeat the process when viewing a different source input, if necessary. Different sources, channels and programs may call for a different setting, depending on the resolution (HD or SD) and aspect ratio of that source or program.
