Da-Lite DL15673LS 104" Tensioned Advantage with SightLine Ultra-Wide Projection Screen (HD Progressive 1.3)

Product Overview

The Da-Lite Tensioned Advantage with SightLine 104" 21:9 Ultra-Wide Projection Screen (DL15673LS) with HD Progressive 1.3 surface is a ceiling recessed 21:9 ultra-wide projection screen with a 1.3 gain surface for installations where projector output requires gain assistance to achieve target brightness at the 104" diagonal. This Da-Lite SightLine floating screen commercial AV product compensates for brightness falloff at longer throw distances, making it the appropriate surface specification when the projector placement and lumen output combination demands additional gain. The 21:9 ultra-wide format serves video conferencing projection screen applications at 47" H x 89" W. Confirm seating geometry against the gain curve prior to specification.

Product Description

The Da-Lite Tensioned Advantage with SightLine is a ceiling-recessed electric projection screen engineered for commercial AV installations. At 104" diagonal in 21:9 ultra-wide format (approximately 47" H x 89" W viewing surface), this model addresses boardrooms and conference rooms with long-throw or lower-lumen projector setups. The SightLine cable-drop system creates a floating screen appearance with 70"/180cm variable positioning. The two-stage installation installs the case during rough-in and the surface assembly during finishing. The HD Progressive 1.3 surface with 1.3 gain compensates for brightness falloff at longer throw distances; note that higher-gain surfaces have a narrower viewing cone. TruGuide electric tensioning, Smooth Roll Technology, LVC, and UL 2043 Plenum Rated case are standard. This Da-Lite commercial projection screen installation carries 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.
• HD Progressive 1.3 Higher-Gain Surface — 1.3 gain surface amplifies projected brightness for longer throw distances or lower-lumen projectors at 104" diagonal; confirm seating geometry before specifying.
• Seamless Viewing Surface — No center seam; maintains visual continuity across the full 104" ultra-wide viewing area.

Typical Applications

• Conference rooms with long-throw projection infrastructure requiring gain assistance
• Boardrooms where projector lumen output requires supplemental gain at 104" diagonal
• Multi-purpose rooms configured for long-throw video collaboration
• Corporate training rooms with extended-throw projector infrastructure
• Government conference spaces with architectural ceiling requirements

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 with 3–4 thin cables, creating a floating screen appearance, 70" variable positioning, and open space for cameras or speakers.

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

A: Yes. LVC integrates with Crestron, AMX, Extron, QSC via dry contact relay. Contact creationnetworks.net for integration assistance.

Q: What projectors are compatible with the HD Progressive 1.3 surface?

A: Designed for longer throw distances or projectors requiring gain assistance at 104" diagonal. Confirm seating geometry against the gain curve before specification. Contact Creation Networks for a projector-screen consultation.

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

A: Yes. UL 2043 Plenum rated per IBC and NFPA 90A requirements.

Q: What is the two-stage installation process?

A: Case installs during rough-in; surface assembly installs during finish phase after painting and ceiling tile work.

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

A: 5-year limited warranty. Contact Creation Networks at creationnetworks.net.
