    For big, bold & better projects

    The 4K Tessera SX40 LED processor combines our industry-leading feature set and easy-to-use software interface with our highest-ever capacity processor.

    Tessera SX40 offers support for full 4K screens at 60Hz with 12 bits per colour output. It supports a zero-latency up/down scaler that matches the source to the screen as well as all of Tessera’s industry-leading processing features. These include HDR and Dynamic Calibration as well as Extended Bit Depth, HFR+ (High Frame Rate), Frame Remapping, and more. Additionally, Stacking can be used to control multiple SX40 processors as one.

    It is compatible with all existing Tessera fixture inventory.

    Used in combination with the Tessera XD Distribution unit, the SX40 provides a cost-effective and powerful system for supporting the biggest and boldest LED projects.

    Extended Bit Depth

    New levels of dynamic range are a free update away! Unlock up to 3.3 additional bits of precision and reap the rewards of superb image quality and maximised HDR content.

    Extended Bit Depth

    With Stacking, multiple processors can be controlled as one. Setups can be as large and versatile as you need them to be – with quicker, greatly simplified control.

    Tracking Markers

    Our Tracking Markers feature is compatible with the Mo-Sys StarTracker system and overlays configurable tracking markers onto your displayed video content.

    Operating Modes

    Changing between Operating Modes is quick and easy, and it puts the final decision on which aspect of visual performance is most important back in the hands of the user.

    Operating Modes

    ShutterSync tunes the LED screen to the camera, not the other way around, giving back creative flexibility for camera configuration.

    Frame Remapping

    Frame Remapping makes it possible for multiple cameras to each see different content when viewing the same LED screen at the same time.

    Frame Remapping
    3D LUT

    Import a 3D LUT directly into your Tessera software project file, for advanced colour management capabilities.

    3D LUT
    HFR+ (High Frame Rate)

    HFR+ offers the power to play video content on an LED screen at up to 250 fps (frames per second).

    HFR+ (High Frame Rate)
    Ultra Low Latency

    Ultra Low Latency reduces the end-to-end latency to just 1 frame, providing a solution for broadcast television and film industries.

    Ultra Low Latency

    High Dynamic Range offers greater brightness and colour ranges with a higher bit depth, appearing perceptibly sharper and more detailed for vivid, lifelike images.


    Provides real-time compensation for thermal artefacts such as pink/cyan pin-cushioning, and gradients due to swapped modules.


    Limitations in the driver chips, LEDs and panel electrical design can be overcome to ensure neutral colour balance across the entire greyscale.

    Dark Magic

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

    Dark Magic

    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.


    Offers powerful and intuitive colour correction with two operating modes – 14 Way Colour Corrector and Colour Replace. Easily and independently adjust primary, secondary and tertiary colours.


    The Tessera system is genlocked from the video input all the way down to the LED refresh cycle, giving perfectly smooth video with no dropped or doubled frames.


    Delivers ultimate peace of mind for users by introducing an auto-failover mechanism that allows a back-up processor to take over in just a few seconds.

    Tessera Software

    Tessera Management Software gives you full control over your Tessera System, with an array of powerful, easy-to-use features for an impeccable show every time.

    Tessera SX40 LED Processor with XD Data Distribution Unit
    tessera xd distribution unit

    The Tessera XD 10G data distribution unit works seamlessly with the Tessera SX40 LED processor to deliver a flexible, sophisticated single box solution designed specifically to easily and cost-effectively support the biggest LED projects.

    The Tessera SX40 processor and Tessera XD data distribution unit support both copper and single mode optical fibre trunk connections, and the Tessera XD can be used to convert between the two media.

    Trunk connections between a Tessera SX40 and Tessera XD, or between Tessera XD units, use a 10G Ethernet-based backbone to reduce the number of home-run connections required.

    custom input resolutions

    Unusual shows have unusual content. With the Tessera SX40 you can build a screen of almost any size and dimension and be sure that your content plays beautifully on it.

    For complete flexibility and creative control, the Tessera SX40 processor accepts custom input resolutions.

    Processor redundancy diagram

    Redundancy delivers ultimate peace of mind for users by introducing an auto-failover mechanism that allows a back-up processor to take over in just a few seconds.

    Tessera LED processors can be fed from the same or independent video sources, with different formats, resolutions, and/or frame rates.

    There’s no requirement for any aspect of the sources to match – redundancy will ensure a near-seamless show even in the event of a power or cable failure.

    “The Brompton SX40 processor is by far the most advanced and user-friendly LED control hardware & software on the market – it’s an LED tech’s dream to operate. The auto detection of panel quantity and type per string is very helpful, while the fantastic XDs really aid with cable management and cabling options, the engineers and designers have really thought of everything you would want in a 2U bit of kit. We often use it in high pressure, tight timescale environments, and the SX40 is a pleasure to work with, never letting us down.”
