4. Setup and Installation

4.1 Choosing a Location

• Select a wall that is structurally sound and free from obstructions.
• Consider the viewing angle for projection and accessibility for dry erase use.
• Avoid direct sunlight or strong ambient light sources that could affect projection quality.

4.2 Mounting Instructions

1. Measure and Mark: Carefully measure the desired height and center point for the screen on the wall. Use a level to ensure the mounting points will be perfectly horizontal. If an installation template is provided, use it.
2. Drill Pilot Holes: Based on your measurements and the type of mounting hardware provided, drill appropriate pilot holes into the wall. Ensure you are drilling into wall studs or using suitable wall anchors for drywall.
3. Attach Mounting Brackets: Securely fasten the mounting brackets to the wall using the provided screws and anchors. Double-check that the brackets are firmly attached and level.
4. Lift and Hang: With assistance, carefully lift the screen and align its mounting points with the installed wall brackets. Gently lower the screen onto the brackets, ensuring it is securely seated.
5. Final Check: Verify that the screen is level, stable, and securely mounted to the wall.

5. Operating Instructions

5.1 Using as a Projection Screen

The Da-Lite 28273T features a matte screen surface, designed to reduce glare and provide clear image projection.

• Projector Placement: Position your projector to align the image with the screen's 87-inch diagonal display area (46"W x 73.5"H, 16:10 aspect ratio). Adjust the projector's keystone correction and focus for optimal image quality.
• Lighting Conditions: For best projection results, minimize ambient light in the room. The matte surface helps, but excessive light can still wash out the image.

5.2 Using as a Dry Erase Whiteboard

The screen surface also functions as a dry erase whiteboard.

• Markers: Use only high-quality dry erase markers. Avoid permanent markers, as they will stain the surface.
• Erasing: Use a dedicated dry erase board eraser or a soft, clean cloth to remove markings. Erase promptly after use to prevent ghosting.

6. Maintenance and Care

Proper maintenance will extend the life and performance of your Da-Lite screen.

• Cleaning the Screen Surface:
  • For dry erase marks, use a clean, soft dry erase eraser.
  • For stubborn marks or general cleaning, lightly dampen a soft, lint-free cloth with water or a mild, non-abrasive whiteboard cleaner. Wipe gently and dry immediately with another clean, dry cloth.
  • Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the screen surface.
• Frame Cleaning: Wipe the frame with a soft, damp cloth. Avoid getting moisture into any internal components.
• Inspection: Periodically inspect the mounting hardware to ensure it remains secure.
