Da-Lite DL15691L 174" Tensioned Advantage with SightLine Ultra-Wide Projection Screen (Parallax Stratos 1.0)

Product Overview

The Da-Lite Tensioned Advantage with SightLine 174" 21:9 Ultra-Wide Projection Screen (DL15691L) with Parallax Stratos 1.0 surface is designed for large-format commercial boardrooms, all-hands facilities, and hybrid conference rooms requiring a premium ceiling-recessed electric projection solution. This Da-Lite SightLine floating screen commercial AV product delivers an ALR (ambient light rejecting) surface in a 21:9 ultra-wide format ideal for video conferencing projection screen applications. The Parallax Stratos 1.0 surface performs in rooms with uncontrolled ambient light, making it equally effective for hybrid video conferencing and executive presentation environments. As a ceiling recessed 21:9 ultra-wide projection screen, this model supports both ultra-short-throw and standard-throw projectors without compromise.

Product Description

The Da-Lite Tensioned Advantage with SightLine is a ceiling-recessed electric projection screen engineered for commercial AV installations requiring architectural integration and high performance. At 174" diagonal in 21:9 ultra-wide format (approximately 79" H x 148" W viewing surface), this screen delivers a commanding presence in large boardrooms and all-hands facilities. The SightLine cable-drop system replaces traditional black drop fabric with 3-4 thin cables, creating a floating screen appearance and enabling variable vertical positioning within a 70"/180cm range after installation. This adjustability allows the screen to be precisely positioned relative to cameras, speakers, or audience sightlines without cutting additional ceiling openings. The Da-Lite Tensioned Advantage features a two-stage installation process: the aluminum case and mounting hardware are installed during the rough-in construction phase, and the surface assembly is fitted during the finish phase after painting and ceiling tile work is complete, reducing coordination requirements between AV contractors and other trades. The 21:9 ultra-wide format is purpose-built for hybrid video conferencing solutions, allowing simultaneous display of in-room participants on one side and remote participants on the other without image cropping or letterboxing. The Parallax Stratos 1.0 ALR surface with 1.0 gain is optimized for high-ambient-light environments and is compatible with both ultra-short-throw laser projectors and standard-throw commercial projectors. TruGuide electric tensioning maintains uniform surface tension across the full 148" viewing width, eliminating wrinkles and wave distortion common in large-format untensioned screens. Smooth Roll Technology protects the viewing surface during retraction cycles, maintaining a flat projection surface over the product’s service life. Low Voltage Control (LVC) provides clean integration with Crestron, AMX, Extron, QSC, and other commercial AV control systems via dry contact relay. The UL 2043 Plenum Rated aluminum case meets commercial building code requirements for installation in HVAC plenum return air spaces, and the white powder-coated closure door eliminates the need for additional ceiling trim work after installation. This Da-Lite commercial projection screen installation is backed by a 5-year limited warranty.

Key Features

• SightLine Cable-Drop System — Replaces black drop fabric with 3–4 thin cables, creating a floating screen appearance and allowing variable vertical positioning up to 70" from ceiling to screen top edge.
• 21:9 Ultra-Wide Format — Designed for hybrid video conferencing solutions displaying in-room and remote participants simultaneously on a single surface.
• Two-Stage Installation — Case installs during rough-in construction; surface assembly during finishing stage, reducing coordination requirements between trades.
• TruGuide Electric Tensioning System — Maintains uniform surface tension across the full viewing area to eliminate wrinkles and surface distortion.
• Smooth Roll Technology — Prevents surface deformation during retraction cycles, maintaining flat viewing surface over the product’s service life.
• Standard Low Voltage Control (LVC) — Integrates with third-party AV control systems via dry contact relay without requiring high-voltage switching at the control point.
• UL Plenum Rated Case — Approved for installation in plenum air spaces per UL 2043, meeting commercial building code requirements in most jurisdictions.
• Ceiling Trim-in-Place Design — White powder-coated aluminum case with closure door conceals the ceiling opening; no additional trim work required after screen installation.

• Government conference spaces with architectural ceiling requirements

Technical Specifications

Frequently Asked Questions

Q: What is the SightLine feature and how does it differ from standard black drop?

A: SightLine replaces the traditional black fabric drop above the screen with 3–4 thin cables. This creates a floating screen appearance, allows the vertical position of the screen to be adjusted within a 70" range after installation, and provides open space above the viewing area for camera or speaker placement—without cutting additional ceiling openings.

Q: Is this screen compatible with standard AV control systems?

A: Yes. The standard Low Voltage Control (LVC) integrates with Crestron, AMX, Extron, QSC, and other control systems via dry contact relay. Optional RS-232 (SCB-100/SCB-200) and screen trigger (Video Projector Interface) configurations are also available. Contact our team at creationnetworks.net for integration assistance.

Q: What projectors are compatible with the Parallax Stratos 1.0 surface?

A: The Parallax Stratos 1.0 ALR surface is compatible with both ultra-short-throw (UST) laser projectors and standard-throw commercial projectors. Its ambient light rejecting properties make it particularly effective in rooms with windows, overhead lighting, or other uncontrolled light sources.

Q: Can this screen be installed in a plenum air handling space?

A: Yes. The case is UL 2043 Plenum rated, meeting the requirements for installation in HVAC plenum return air spaces as required by the International Building Code (IBC) and NFPA 90A in commercial construction.

Q: What is the two-stage installation process?

A: During the rough-in construction phase, the screen case and mounting brackets are installed and the ceiling is closed. The surface assembly is then installed during the finish phase after painting and ceiling tile work is complete. This eliminates coordination issues between the screen installer and other trades.

Q: What warranty does Da-Lite provide on this product?

A: Da-Lite provides a 5-year limited warranty covering manufacturing defects. For warranty service or technical support, contact Creation Networks at creationnetworks.net.
