Novastar MRV416 LED Display Receiver Card With 16 Ports
Introduction
The MRV416 is a general receiving card developed by Xi’an Nova Star Tech Co., Ltd. (hereinafter referred to as Nova Star). A single MRV416 supports resolutions up to 512×384@60Hz (Nova LCT V5.3.0 or later required).
Supporting various functions such as the 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.

Features
Improvements to Display Effect
⬤Brightness calibration
Work with the high-precision calibration system to perform brightness calibration on each LED to effectively remove brightness differences, enabling high brightness consistency.
⬤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 Nova LCT (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 non- uniformity under low grayscale and white balance offset, allowing for a more realistic image.
Improvements to Maintainability
⬤Quick 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.
⬤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.
Improvements to Reliability
⬤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.
Nova LCT V5.2.0 or later is required.
⬤Firmware program read back
The receiving card firmware program can be read back and saved to the local computer.
Nova LCT V5.2.0 or later is required.
⬤Configuration parameter read back
The receiving card configuration parameters can be read back and saved to the local computer.
⬤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 program backup
Two copies of firmware program are stored in the application area of the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.
