Display adjustment
Calibration adjusts individual LED output to improve consistency. Bright/dark-line adjustment targets visible lines at cabinet or module boundaries. Independent RGB Gamma provides separate control of the three color channels when supported by the sending controller and NovaLCT configuration.
For 3D operation, use a compatible controller and configure the 3D parameters through NovaLCT or the controller panel. The receiving card alone does not establish compatibility for the complete screen.
Locating faults and keeping configuration records
Mapping displays receiving-card numbers and network-port information on the cabinet, helping identify the physical wiring. Temperature and voltage can be viewed in NovaLCT without additional sensing peripherals. Network error counts help investigate connections between sending devices and receiving cards or between cards.
Firmware and configuration parameters can be read back and saved locally. Loop backup uses primary and standby network paths, while the factory dual-program arrangement supports recovery when a program update encounters a problem. Configure and test the actual backup wiring before relying on it.

DH426 FAQ
How many HUB75 connectors does DH426 have?
It has sixteen HUB75 connectors and supports up to 32 groups of parallel RGB data.
How can I identify a DH426 card inside an LED wall?
Enable Mapping in NovaLCT to display the receiving-card number and network-port information on the target cabinet.
Can DH426 monitor temperature and voltage?
Yes. Its own temperature and voltage can be viewed through NovaLCT without additional sensing peripherals.
Can I back up the receiving-card configuration?
NovaLCT can read back configuration parameters and save them locally. Firmware readback is also listed.
Does DH426 support independent RGB Gamma and 3D?
Both functions are listed, but they require compatible sending equipment and software settings. Check the complete system and relevant parameters before enabling them.
