    The Tessera S4 LED processor is the workhorse of the Tessera range – perfect for large, high resolution video walls. It has full HD support, with a standard canvas of 1920×1080 @ 60Hz, and more non-standard canvases available.

    It retains Tessera’s class-leading quality and control with a smaller creative feature set to ensure competitive value.

    The Tessera S4 has up to nominal 2.1 million pixel output and sophisticated colour controls including; per-input adjustments, global brightness & gamma, and On-Screen Colour Adjustment (OSCA).

    You can also rotate fixtures to 0˚ / 90˚ / 180˚ / 270˚ and place them anywhere on the full HD canvas (regardless of the order in which they are cabled), removing the need for external pixel mapping.

    Dark Magic

    Improves the appearance of panels operating at less than their maximum brightness by reducing banding and increasing detail in dark areas.

    On-Screen Colour Adjustment (OSCA) enables a special user interface to appear on the LED screen itself, allowing for quick, easy module and seam selection.

    Sub-fixture mapping

    The Tessera Management Software makes setting up your LED fixtures easy, regardless of number, size or cabling order, offering increased flexibility and much greater creative control over fixtures of any pixel pitch.

    You can place fixtures and sub-fixtures anywhere on the full HD canvas. The Tessera system uniquely supports multiple sub-fixtures from a single R2 receiver card, making mapping creative shows with LED strips and small tiles easier than ever.

    quick association

    Quick Association is a new, even faster way to associate large numbers of panels to your Tessera LED processor.

    Each string of fixtures is automatically assigned a unique numeric code, so it’s quick and easy to select the fixtures you want, associate them with the processor, and place on your canvas. Quick Association is supported by all Tessera processors, in both remote and local UI, to make your fixture setup as efficient as possible.

    CABLE redundancy

    The Tessera S4 processor supports loop-back redundancy, in which pairs of output ports are connected to both ends of a string of fixtures.

    Loop-back redundancy gives you peace of mind in the event that something happens to the primary video source. If the worst happens in a live show, never fear – your panels will automatically switch to the backup feed so that the show continues seamlessly.

    “As a recent start-up, Universal Pixels only invests in video technology with a clearly defined future road map. Tessera provides this and has become the industry standard for LED processing (regardless of panel manufacturer or SMD type) – which helps us hugely, both with technician knowledge, and on the road support.”
