The MRV416 is a general receiving card developed by NovaStar. Working with NovaLCT V5.3.0 or later, a single MRV416 loads up to 512×384 pixels. Supporting various functions such as brightness calibration, quick adjustment of dark or bright lines, 3D, and individual Gamma adjustment for RGB, the MRV416 can greatly improve the display effect and user experience. The MRV416 uses 16 standard HUB75E connectors for communication, resulting in high stability. It supports up to 32 groups of parallel RGB data and is suitable for various on-site setups.
Improvements to Display Effect
Loop backup The receiving card and sending card form a loop via the main and backup line connections. If a fault occurs at a location of the lines, the screen can still display the image normally.
Dual backup of configuration parameters The receiving card configuration parameters are stored in the application area and factory area of the receiving card at the same time. Users usually use the configuration parameters in the application area. If necessary, users can restore the configuration parameters in the factory area to the application area.
Dual backup of the application program Two copies of the application program are stored in the receiving card at the factory to avoid the problem that the receiving card may get stuck due to program update exceptions.
Improvements to MaintainabilityQuick uploading of calibration coefficients
Upload the calibration coefficients quickly to the receiving cards to improve efficiency.
Mapping function The cabinets can display the receiving card number and Ethernet port information, allowing users to easily obtain the locations and connection topology of receiving cards.
The setting of a pre-stored image in receiving card The image displayed on the screen during startup, or displayed when the Ethernet cable is disconnected or there is no video signal can be customized.
Temperature and voltage monitoring The receiving card temperature and voltage can be monitored without using peripherals.
Cabinet LCD The LCD module of the cabinet can display the temperature, voltage, single run time, and total run time of the receiving card.
Bite error detection The Ethernet port communication quality of the receiving card can be monitored and the number of erroneous packets can be recorded to help troubleshoot network communication problems.
NovaLCT V5.2.0 or later is required.
Firmware program readback The receiving card firmware program can be read back and saved to the local computer. NovaLCT V5.2.0 or later is required.
Configuration parameter readback The receiving card configuration parameters can be read back and saved to the local computer.
Improvements to Reliability
Brightness Calibratio Working with NovaLCT and the calibration platform, the receiving card supports brightness calibration on each LED, which can effectively remove brightness differences and greatly improve display brightness consistency, allowing for better image quality. It is recommended that CalCube MiniLED V1.1.0 or later be used as the calibration platform.
Quick adjustment of dark or bright lines The dark or bright lines caused by splicing of modules or cabinets can be adjusted to improve the visual experience. The adjustment can be easily made and takes effect immediately.
3D function Working with the sending card that supports 3D function, the receiving card supports 3D output.
Individual Gamma adjustment for RGB Working with NovaLCT (V5.2.0 or later) and the sending card that supports this function, the receiving card supports individual adjustment of red Gamma, green Gamma and blue Gamma, which can effectively control image nonuniformity under low grayscale and white balance offset, allowing for a more realistic image.
