Introducing the Da-Lite 10101621 Projection Screen

Da-Lite part number 10101621 is a 139.8-inch projection screen. This item is part of our Projection Screens range. Listing details: Da-Lite DescenderPro projection screen 3.55 m (139.8") 16:9.

Key Specifications of the 10101621

The projection screen diagonal is 139.8 inches. The diagonal is listed as 3.55 m. Aspect ratio: 16:9. Aspect ratio should match the projector's native format, such as 16:9, 16:10 or 4:3, to avoid unused screen area. Ultra-short-throw projectors pair best with ceiling-light-rejecting surfaces. Projection screen size is quoted as the diagonal of the viewing area. A common guideline places the first row of seats at least about 1.5 times the screen height away.

Screen Surface and Performance

Electric and motorized screens retract into a case when not in use, keeping rooms flexible. Ambient-light-rejecting and high-contrast surfaces help maintain image contrast in rooms with lighting. A dedicated projection screen gives a brighter, more uniform image than projecting onto a wall. Correct sizing ensures a proper fit. Professional installers can integrate screens into ceilings, walls and furniture. Fixed-frame screens provide a permanent, cinema-style viewing surface for home theatres and dedicated rooms.

About Da-Lite

Da-Lite, part of Legrand AV, has made projection screens for more than a century. Reordering by part number avoids mistakes. Fleet consistency reduces support effort. Screen gain of around 1.0 gives an even image across wide seating areas. Tensioned screens keep the surface perfectly flat for the sharpest images from modern projectors.

Ideal Applications

It is well suited to auditoriums and event venues, as well as simulation and visualization. Another common application is conference and board rooms. Portable and tripod screens set up quickly for training sessions, events and temporary venues. Clear specifications make ordering simple. Clean, organized workspaces look more professional. Low-voltage controls and RS-232 or IP triggers integrate electric screens with room control systems.

Installation Best Practices

Align the projector image to the screen borders. Measure the wall or ceiling space and check projector throw distance. Fix wall or ceiling brackets securely to the structure. Clean the surface only with recommended methods. Electric screens with quiet motors suit classrooms and meeting rooms. Black masking borders sharpen the perceived contrast of the projected image.

Buying Guide

Check mounting options and case dimensions. Choose a surface for your lighting conditions and projector brightness. Match the screen aspect ratio to your projector. Regional versions can differ in plugs and language. Grey surfaces can improve black levels when ambient light cannot be fully controlled. Seamless surfaces avoid visible lines across large images.

Keep It Running Smoothly

Stay within the specified load capacity. Use only recommended cleaning products. Avoid abrasive cleaners on finished surfaces. Rear-projection surfaces let the projector sit behind the screen, out of the audience's way. Screen surfaces have different gains: higher gain reflects more light toward the audience, while lower gain widens viewing angles.

Long-Term Value

Budgeting for refreshes keeps fleets current. Wipe data securely before disposal. Consider total cost of ownership, not just price. Simple installation reduces setup time. Larger rooms need larger screens and brighter projectors to keep images clear.

Compatibility Guide

Allow clearance for cables and connectors. Measure the display or space before ordering. Product documentation lists compatible models and sizes. Check the projector's aspect ratio and brightness. Measure viewing distance when choosing projection screen size. Matte white surfaces are versatile and suit most rooms and projectors. Commercial-grade products are built for frequent use.

Why It Matters

Projection screens deliver big images for presentations and teaching. Protected screens stay clean and scratch-free. Flexible setups adapt to different users and tasks. Professional installations improve the look of offices and venues. Quality materials ensure long service life. Ceiling-recessed screens disappear completely when retracted.
