Proper installation of your projector will ensure the quality of your display. Whether you are
installing a projector temporarily or permanently, you should take the following into
account to ensure your projector performs optimally.

inverted mount. Table 3-2 compares these various installation methods.
Table 3-2. Projector Installation Options
Advantages Considerations
Front Screen, Floor Mount Installation
• Easy to set up
• Can be moved or changed quickly
• Easy to access
• Shares floor space with audience
Front Screen, Inverted Mount (ceiling) Installation
• Does not take up audience space
• Projector is unobtrusive
• Projector cannot be accidentally moved
• Installation is more permanent
• Projector access is more difficult
Rear Screen, Floor Mount with Zero or Two Mirrors (Note)
• Projector is completely hidden
• Projector is easily accessed
• Usually good ambient light rejection
• Requires separate room
• Installation cost is usually higher
• Left and right polarizers must be removed
and switched (refer to Switching,
Cleaning or Replacing the Polarizers on
page 97)
Rear Screen, Inverted Mount (ceiling) Installation
• Projector is completely hidden
• Usually good ambient light rejection
• Requires separate room
• Installation cost is usually higher
Rear Screen, Floor Mount with One Mirror (Note)
• Projector is completely hidden
• Usually good ambient light rejection
• Requires less space behind screen than
other rear-screen installations
• Requires separate room
• Installation cost is usually higher
Note: You must remove and switch the left and right polarizers for a rear-projection installation
with zero or two mirrors, for proper 3D imaging. In a rear-projection installation with one mirror,
the polarizers should remain in their factory-installed positions. For more about rear-projection
installation requirements, refer to Folded Optics on page 28.
