31 Using the projector
4. Wide: Stretches the picture horizontally in a non-linear
manner, that is, the edges of the picture are stretched more
than the center of the picture to prevent distortion of the
central part of the picture. This is suitable for occasions
where you want to stretch the width of a 4:3 aspect picture
to the width of a 16:9 aspect screen. It does not alter the
height. Some widescreen movies have been produced with
their width squashed down to the width of a 4:3 aspect,
and are best viewed when restretched back to their original width using this setting.
5. Real: This setting displays the image in a one-to-one pixel
mapping without alteration or resize in the center of the
projection. This is most suitable for use with PC source inputs.
• The black portions are inactive areas and the white portions are active
areas.
• OSD menus can be displayed on those unused black areas.
Operating in a high altitude environment
We recommend that you activate High Altitude Mode when your environment is higher
than 1500 meters (around 4920 feet) above sea level, or whenever the projector will be
used for extended periods of time (>10 hours) without shutdown.
To activate High Altitude Mode:
1. Press MENU and then press / until the Setup menu is
highlighted.
2. Press to highlight High Altitude Mode.
3. Press / to select On. A confirmation message displays.
4. Highlight Yes and press ENTER.
Operation under High Altitude Mode may cause a higher
decibel operating noise level because of increased fan
speed necessary to improve overall system cooling and
performance.
If you use this projector under other extreme conditions
excluding the above, it may display auto shut-down
symptoms, which is designed to protect your projector from
over-heating. In cases like this, you should switch to High
Altitude Mode to solve these symptoms. However, this is not
to state that this projector can operate under any and all
harsh or extreme conditions.
