Tessera Processor Software 3.1.4
20th May 2021
3.1.4 Issue A
Tessera HD processors (M2, T1 and S4) must be running processor firmware V2.3.2 or later prior to upgrading to V3.0.1 or later.
M2/T1/S4 upgrade warning
Tessera HD processors (M2, T1 and S4) must be running processor firmware V2.3.2 or later prior to upgrading to V3.0.1 or later, or the upgrade will fail requiring a SD card restore.
Tessera S8 Compatibility
The Tessera S8 processor requires software version 3.0 or later.
HFR+ (High Frame Rate)
Our Tessera SX40 and S8 processors now support operation at up to 250fps. This provides a number of benefits such as Reduced Motion Blur, Lower Latency and the ability to do slow motion visual effects.
HFR+ support is enabled by configuring the canvas for the desired resolution and framerate. The processor’s EDID will advertise the new capabilities to enable HFR+ output from compatible source equipment.
Increasing the frame rate will reduce the maximum pixel count due to HDMI/SDI bandwidth limits. Similarly, the number of pixels supported per 1G output will decrease in inverse proportion to the frame rate in use.
It is also possible to operate panels in HFR+ mode with a standard frame rate video (or genlock) input by using Frame Remapping. The maximum multiplier has been increased to x10, to support multiplying the lowest supported input frame rate of about 24fps to the highest supported integer-multiple output frame rate of 240fps.
The maximum frame rate available will depend on the panel type(s) in use and may range from 60 fps (which all panels support) to a maximum of 250fps. The maximum frame rate for each panel type may be viewed in the processor’s Fixture Library screen (or using Tessera Remote in Offline Editor mode if no hardware is available).
In some cases, the LED driver chip operating bit depth may be automatically reduced when operating at higher frame rates. This may be checked using the panel OSD, but is typically compensated for by Dark Magic, which operates even more effectively at a higher frame rate.
New panel designs will automatically gain HFR+ support, provided the panel hardware supports it.
Frame Remapping allows the user to interleave different areas of the video raster or solid colours in the output.
At its most simple Frame Remapping allows the output frame rate to be doubled so that a black frame can be inserted between every frame of actual content – a useful technique for reducing motion blur. Enabling Frame Rate Multiplication will now enable each of the (up to ten) output frames to be configured to display either video content or a solid colour.
For example: to interleave a black frame with each frame of the incoming video, set the Multiplier to 2, and set the relevant output frame to Colour. By default this is black.
Clicking on the colour chip opens a colour picker that allows any 24-bit colour to be chosen, either using the colour picker itself, which can be set to RGB or CMY modes or by entering the desired RGB (or CMY) or HSI values.
Warning: Frame Remapping could be used to create flashing or flickering effects, with potential to cause disorientation or discomfort, or to be a risk factor for photosensitive epilepsy.
All processors now support control using standard IP based methods for tighter integration with third party or custom control systems. The following protocols are supported, allowing both status monitoring and remote control of key screen parameters such as brightness or input source. More to be added in future:
- HTTP on port 80
- Telnet on port 23

S4 firmware reload
When upgrading an S4 processor to/from 3.1.0.BETA4 firmware, after firmware reload has finished, the processor will not reboot automatically and will require a manual reboot. After reboot, the processor will operate as normal.
In order to use V3.0.1 or later, it is necessary to run all elements of the system (processor, XDs and panels) on V2.3.1 or later. For panels where V2.3 firmware is not available please continue using V2.2 processor firmware.
Restore factory defaults/format SD card can cause fixture library instability
If you perform either of these operations please reboot your processor before browsing to the fixture library window as this may otherwise be unstable.
Settings from Tessera Control are not applied to newly discovered fixtures
If using Tessera Control to alter Brightness, Temperature or Gamma, these settings are not sent to newly discovered fixtures until a change is made to the value.
Tessera Remote and Tessera Control may not work on Mac OSX El Capitan
When running on a Mac OSX El Capitan the Tessera Remote and Tessera Control applications can fail to detect network ports. This appears to be limited to cases where no default gateway is specified on the computer’s network interface. In situations where no default gateway is set using DHCP, we recommend specifying a default gateway manually. PCs running Windows and Macs running OSX Yosemite or earlier are not affected.
Tessera Remote may fail to import project files
In some cases, Tessera Remote may fail to import project files from local storage. As a workaround create the project from scratch or use a local monitor, keyboard and mouse to import the project file before connecting with Tessera Remote.
Some input devices on KVM switches do not work
We have had reports that trackpads may not function correctly when connected to the processor via a KVM switch. As a workaround we recommend using a mouse, or connecting input devices directly to the processor’s USB ports.
Monitors connected via DisplayPort-to-VGA adapters may be unstable
Local user interface monitors connected to the processor via certain active DisplayPort-to-VGA adapters may give an unstable image or the monitor is not detected at all. As a workaround we recommend using a DVI or DisplayPort monitor.
