Da-Lite Tensioned Cosmopolitan 123" Electric Projection Screen

The Da-Lite Tensioned Cosmopolitan 123" Electric Projection Screen is engineered for professional-grade performances in classrooms, conference rooms, and home theaters alike. This large-format, motorized screen blends dependable Da-Lite craftsmanship with a sleek design that blends into any room aesthetic. The tensioned fabric ensures a perfectly flat viewing surface across the entire diagonal, minimizing waves and distortion so you can enjoy crisp, uniform images from edge to edge. With its durable, white powder-coated housing and black backing, it delivers bright, high-contrast front-projection performance while keeping ambient light from washing out the picture.

• Large-format, 123" diagonal for immersive viewing — The expansive 123-inch diagonal creates a sizable viewing surface ideal for presentations, training sessions, and cinematic experiences, delivering a comfortable viewing distance for larger audiences while preserving detail and clarity.
• Tensioned front-projection surface — The tensioning system keeps the fabric taut and flat, minimizing wrinkles and ripples so images stay sharp and vibrant even at the screen edges. This feature is essential for data-heavy slides, video, and fine text in professional environments.
• Electric motor with Decora-style three-position wall switch — Smooth, quiet operation lets you raise and lower the screen with a dedicated wall switch, keeping the installation clean and convenient. The three-position switch provides quick control for fully open, fully closed, and positioned stops as required.
• Ceiling- or wall-mounted installation — Flexible mounting options give you the freedom to place the screen where space and room layout require. Whether you prefer flush ceiling mounting or wall-adjacent placement, the Cosmopolitan line is designed to fit a variety of room geometries.
• White powder-coated housing with black backing — The compact, clean housing complements modern interiors while the black backing ensures optimum brightness by preventing light bleed from the rear, preserving image quality on front-projection surfaces.

How to install Da-Lite Tensioned Cosmopolitan 123" Electric Projection Screen

• Step 1: Plan the mount location. Confirm structural support and ensure there is a nearby power outlet for the screen’s motorized housing. Verify ceiling or wall mounting can accommodate the 123" diagonal surface and the weight of the housing and fabric.
• Step 2: Gather mounting hardware. Use the hardware provided by Da-Lite for ceiling or wall installation, and have a stud finder, level, and appropriate fasteners on hand. If mounting to a ceiling, locate joists or structural members to secure the brackets.
• Step 3: Attach mounting brackets. Secure the appropriate brackets to the ceiling or wall according to the installation template. Make sure brackets are level and evenly spaced to distribute weight and maintain proper screen alignment.
• Step 4: Route power and connect controls. Plug the screen’s motor into a dedicated power outlet and connect the wall switch if it’s not already wired. Ensure the switch is functioning correctly and positioned for easy access in the room.
• Step 5: Mount and align the screen. Hang the screen assembly on the brackets, then align the housing so the screen retracts and extends smoothly without obstruction. Check that the screen deploys fully and stops at the correct stop position.
• Step 6: Test performance and environment. Power on the screen and verify the projection surface is clean and wrinkle-free. Test contrast and brightness with your projector, adjusting projector settings if needed to optimize the image for the room’s lighting conditions.
