Calibration and Display Setup
Pixel-level brightness and chroma calibration works with NovaStar’s calibration system. Quick adjustment of dark or bright lines helps correct visible seams between modules or cabinets. The specification also lists RGB independent gamma adjustment and 3D output when paired with a sending card that supports 3D.
Calibration coefficients can be uploaded quickly. Mapping displays receiving-card numbers and Ethernet port information, and a stored image can be configured for startup, Ethernet disconnection or absence of a video signal.
Monitoring and Backup
The card monitors its own temperature and voltage and supports a cabinet LCD for temperature, voltage and runtime information. Ethernet bit-error detection and firmware readback require NovaLCT V5.2.0 or later. Configuration parameters can also be read back to a local computer.
Loop backup connects the sending card and receiving cards through primary and backup lines. Dual program backup stores two firmware copies to assist recovery from an abnormal update.
