CONTOUR TNSD 137D hd1.0

The Da-Lite CONTOUR TNSD 137D hd1.0, SKU 21864LS, is identified as a tensioned Contour Electrol wide-format projection screen. The supplied records associate the model with a 137-inch diagonal, listed dimensions of 72.5 x 116 inches, and an LVC configuration. Because the available sources contain limited technical documentation and conflicting surface labels, this listing emphasizes confirmed identifiers and the details that should be verified before ordering.

Ideal Use Cases

This model is best considered for a specification-matched installation requiring the Tensioned Contour Electrol series, a 137-inch screen size, and the 21864LS identifier. Its listed wide-format proportions make it relevant to rooms planned around a large projection image. The clearest use case is a new installation, replacement, or procurement project in which the model, dimensions, and control configuration can be checked against an existing design. Buyers should confirm that the room, projector placement, sightlines, and available mounting space accommodate the stated screen geometry.

Why Choose This Model

The principal reason to select this model is its specific combination of series, size, and configuration. The product name identifies a tensioned screen in the Contour Electrol family, while the supplied URLs connect SKU 21864LS with a 137-inch format and LVC configuration. This provides several concrete reference points for matching the screen to a project schedule or equipment list. The tensioned designation is part of the documented product identity, although the supplied data does not quantify surface flatness, border dimensions, case finish, or operating characteristics.

Installation and Integration

Installation planning should begin with SKU 21864LS and the full model name rather than relying on size alone. One supplied source URL lists dimensions of 72.5 x 116 inches; however, it does not establish whether these measurements describe the viewable image, overall screen, or another dimensional reference. Confirm that distinction before calculating clearances. The source data also does not provide case length, mounting centers, total drop, mounting hardware, cable-entry location, voltage, or power consumption.

LVC appears in a supplied product reference, but no compatible controls, wiring requirements, or included accessories are documented. An installer should therefore verify the exact LVC implementation and all required supporting components. Mounting method, structural requirements, electrical provisions, and control integration should also be confirmed from documentation tied directly to SKU 21864LS.

Performance Highlights

The confirmed performance-related attributes are the tensioned construction, wide-format classification, 137-inch size, and hd1.0 designation in the supplied product title. The listed 72.5 x 116-inch proportions mathematically correspond to an approximately 16:10 image format and a roughly 137-inch diagonal, but the actual viewable area should still be verified. No supported claims are available for screen gain, viewing angle, ambient-light behavior, color neutrality, uniformity, or material composition.

This product is a projection screen rather than a projector. Projector specifications such as native resolution, brightness, contrast ratio, HDR support, lens shift, refresh rate, input lag, and connectivity are therefore not established for this listing. Image results will also depend on the separate projector and the completed room configuration.

What Makes It Different

Within the provided information, this model is distinguished by the combined Tensioned Contour Electrol naming, 137-inch designation, wide-format geometry, LVC reference, and SKU 21864LS. Those identifiers make it possible to distinguish this configuration from similarly named screens whose surface, size, or controls may differ. The supplied title uses the designation hd1.0, while another supplied source URL identifies SKU 21864LS with HD Progressive 1.1. That discrepancy is material and should be resolved before purchase rather than treating the two descriptions as interchangeable.

Final Assessment

The CONTOUR TNSD 137D hd1.0 is a focused choice for projects already calling for a Da-Lite tensioned Contour Electrol screen in the listed 137-inch class. Its most dependable ordering reference is SKU 21864LS. Before finalizing the purchase, confirm the precise screen-surface designation, the meaning of the 72.5 x 116-inch dimensions, the aspect ratio, the LVC implementation, mounting requirements, electrical details, included components, and warranty. The available data supports identifying the product and planning an initial fit check, but it is not complete enough to substitute for configuration-specific installation documentation.
