Installation 
Considerations
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.
Installation Type
Choose the installation type that best suits your needs: front or rear screen, floor mount or 
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 
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.
