Tessera SX40 Full 4K LED Proceessor


Tessera SX40 combines Tessera’s industry-leading feature set and easy-to-use software interface with our highest-ever capacity processor.
Compatible with all existing Tessera fixture inventory, together with Tessera XD Distribution, SX40 provides a powerful toolkit for easily and cost-effectively supporting the biggest LED projects.

Support for full 4K screens, at 60Hz with 12 bits per colour output. Latency-free 4K up/down scaling to match the source to the screen.

Up to 4096 x 2160 resolution (currently progressive only)

23.98Hz to 60Hz framerate

8,10 and 12 bits per channel colour depths

RGB 4:4:4 and YCbCr 4:4:4 and 4:2:2

Compatible with DVI-D and DisplayPort sources via adapters

HDCP not supported

Genlock reference

with buffered thru

Supports bi-level and tri-level analog sync signals


4 x 10G BASE-T Tessera XD copper output ports


Supports Neutrik EtherCON Cat 6A / etherCON (CAT5e) connectors

Compatible with standard Cat6A / Cat5e RJ45 connectors

Requires Cat6A cable (up to 60m) or Cat5e cable (upto 30m)

4 x 10G BASE-LR Tessera XD fibre output ports

Supports Neutrik opticalCON DUO / DUO ARMORED / DUO X-TREME / DUO LITE connectors

Compatible with standard LC-Duplex connectors

Requires 1310nm, 9/125um single-mode fibre (up to 2KM) with PC or UPC connectors

Each 10G output independently auto-switches between fibre and copper

Redundant 10G and 1G cabling support (coming soon)

10G copper ports automatically switch to 1G mode if connected directly to panels without an XD (coming soon)

Port capacity is reduced to that of a single 1G port

All normal panel operations are available, including display of video, test patterns and firmware update

Each XD provides ten 1G output ports for connection to fixtures

Each 1G port supports a nominal 525k pixels at 8bpc, 60Hz

Pixel capacity per 1G port scales according to selected bit depth and framerate


Full 4K 4096 x 2160 resolution

Internal processing at full 12 bits per channel (36 bits per pixel), full 4:4:4 colour sampling

Fast, clean input switching

Per-input proc-amp style colour controls with histogram preview

Black level, contrast, hue, saturation, R/G/B shadow, R/G/B highlight

Zero-Latency Scaler

Broadcast quality up/down scaler

Scale any input resolution to any output resolution between 32x32 and 4096 x 2160

No additional latency with scaler enabled

Zero-Latency ChromaTune

14-way Colour Corrector and Colour Replace modes

No additional latency with ChromaTune enabled

Built-in hardware-generated test patterns

Pixel-perfect geometry

Frame-perfect scrolling

Still frame store

Images may be imported from PNG/JPEG files

Frames may be captured from the video input

Freeze and Blackout

Progressive video only (interlaced video currently not supported)


Up to 9 Million Pixels at any bit depth and framerate

Fixtures smaller than 64x64 pixels have additional processing overhead and therefore result in reduced capacity

Sub-fixtures and root notes are not supported

Up to 2000 fixtures

Multiple fixture types supported simultaneously

Free placement of fixtures anywhere on the canvas

Rotation of fixtures to 90˚, 180˚ or 270˚ (coming soon)

1:1 pixel alignment for perfect mapping of input pixels to LEDs

On-Screen Colour Adjustment (OSCA) mode

Real-time selection of fixture seams and modules using a mouse cursor on the LED screen itself

Adjustment of seam brightness to compensate for ageing and different LED batches

Adjustment of module colour output to compensate for ageing and different LED batches

Global output adjustments

Screen brightness (Nits)

Colour temperature adjustment (K)

Gamma value

Low End Boost to increase brightness in dark areas of the image

Dark Magic to reduce banding and increase detail in dark areas of the image

Per-group output overrides

Optionally set output adjustments independently for each group of fixtures


Lock to either video input, regardless of which input is currently active

The frame rate of the internal reference can be set by the user.

Frame rates from 23.98 to 60Hz are supported.

Genlock is system-wide, all the way through to the LED refresh within the fixtures, ensuring rock-solid lock to the selected timing source


2 frames end-to-end system latency with all features enabled

Equivalent to HD processors' low-latency mode, but without any loss of video processing features

May optionally be configured to add up to 4 additional frames of latency to match other (slower) display devices
