TS921 Linsn Synchronous LED Screen Sending Card - Reliable 4K Input

In this review the TS921 Linsn Synchronous LED Screen Sending Card is evaluated for installers and AV technicians who need a compact, compatibility-focused sending card. The bottom line: it is designed to accept modern video sources, including 4K input, and deliver stable output via a PCI-E 1X connection, making it a sensible choice for projects that require straightforward signal handling and support for RCG/CON file broadcasting. The card's low overall consumption and wide operating temperature range also make it a durable option in mixed environments.

Key Features

• 4K video input support: Accepts high-resolution video sources so it can handle detailed content for large LED screens without forcing a source change.
• DVI signal input: One DVI input simplifies connection from many common video sources and adapters used in live and fixed installations.
• File broadcast and readback: Supports broadcasting and reading back RCG and CON files, which streamlines content deployment and configuration management.
• Flexible color depth: Accepts 12-bit, 10-bit, and 8-bit video inputs and supports 16-bit grayscale display for finer gradation and improved image fidelity.
• PCI-E 1X compatibility: Uses a standard PCI-E 1X port for broad computer compatibility and easier integration into existing control systems.
• Dual port output capability: Supports high combined resolutions such as 2048x640 and 1280x1024 for varied screen layouts and tiling configurations.

Who It's For

The TS921 is aimed at AV integrators, rental companies, and system builders who need a compact sending card that accepts contemporary video sources and supports file-based workflows. Its support for file broadcasting and multiple bit-depths is useful for teams that manage many LED panels and require reproducible configuration across show runs.

Users who need advanced processing features like onboard scaling, built-in media playback, or multichannel redundancy should look elsewhere, since this card focuses on reliable input/output and file broadcast rather than a full media server feature set.

Pros & Cons

Pros

• Supports 4K video input, allowing use with high-resolution sources without extra converters.
• Low overall consumption at 2.5W helps reduce rack power draw for multi-card setups.
• Wide operating temperature range (-20C to 75C) makes it suitable for varied environments.
• PCI-E 1X interface improves compatibility with most host systems.

Cons

• Limited to one DVI input and one audio input, so it is not intended as a multi-source switcher for complex live mixing.
• The card is compact and specialized, which may lack advanced on-card processing some users expect from a full media controller.
