Advanced Functions
. 3 independent layers
Support up to 3x 4K layers and layer priority adjustment in Z order.
. Image scaling
Support 3 image scaling modes: custom, pixel to pixel, and snap to canvas
. Color Replacement
Support free replacement of any color on the image without affecting the performance of other colors. Replacement of highly saturated colors is recommended for better effect.
. 14Ch Color Correction
Support precise adjustment to hue, saturation and brightness of black, white and the 12 derived standard colors of the red, green and blue primary colors.
. Curves
Support adjustment to the image RGBW mapping curves.
. 3D LUT
The 17×17×17 3D LUT .cube files are supported to adjust the video source colors.
. Dynamic Booster
Real-time analysis and dynamic adjustment are made to each frame to significantly improve the display contrast and image details for better visual experience, and effectively control and lower the display power consumption, extending the service life of the LED screen.
. Full Grayscale Calibration
Work with NovaStar’s high-precision calibration system and the C3200 scientific grade camera to generate unique calibration coefficients for each grayscale, ensuring uniformity of each grayscale and dramatically improving the image quality.
. HDR
- Support HDR10 and comply with the SMPTE ST 2084 and SMPTE ST 2086 standards.
- Support HLG.
. Latency
- Support low latency and the controller load capacity is not reduced. The latency at the controller is 0 frame (less than 1 ms) in Send-Only Controller working mode and 1 frame in All-In-One Controller working mode.
- Support additional latency. Zero to two frames of latency can be added at the controller.
. No rectangle restriction
No rectangle restriction for irregular screens.
When calculating resolutions, blank pixels do not count towards the total capacity. The used load capacity of Ethernet ports is the sum of the pixels of all cabinets.
. Frame Rate Adaptive
The controller can be adaptive to various video input frame rates, including decimal frame rates.
Custom frame rates are also supported and the step size of fine tuning frame rate is as small as 0.01 Hz.
. Two working modes
Support the All-In-One Controller and Send-Only Controller working modes.
- In the Send-Only Controller mode, the latency can be reduced by one frame.
- In the All-In-One Controller mode, the layer and scaling functions are available.
. Display system monitoring
Support monitoring of the device status and screen status. Any fault and alarm information can be reported actively.
Device Controls
. Touch LCD
Come with a 5.5-inch 1080p touch LCD. It is sensitive and rugged, allowing users to control the device easily by tapping on the LCD.
. VMP software control
The device can be connected to the VMP software to provide easy and convenient operations and smart device management.
. Cascading control via Ethernet
The Gigabit Ethernet control ports support TCP/IP protocol and star topology. No switch or router is needed to deploy multiple devices on the same LAN via device cascading as the network switching function is already built in.
Table 1-1 Function limitations
Function | Limitation |
Frame Rate Adaptive | This function can be achieved when the CX40 Pro works with the CA50E, CA50C, or XA50 receiving card. Currently supported driver ICs include ICND2055, ICND2065, ICND2069, ICND2076, MBI5264, MBI5264B, and MBI5264C. In addition, the .ncp
file generated by the Cabinet Tool from NovaStar must be used. |
Dynamic Booster | This function can be achieved when the CX40 Pro works with the CA50E, CA50C, or XA50 receiving card. Before operation, brightness and color gamut correction using the CA410-VP427, CA410-P427 or EYE2-400 color analyzer must be completed. |
Full Grayscale Calibration | This function can be achieved when the CX40 Pro works with the CA50E, CA50C, or
XA50 receiving card. A C3200 camera is required to perform full-grayscale calibration. |
Low Latency | The Low Latency and Genlock functions are mutually exclusive. To enable low latency, please make sure all Ethernet ports load the cabinets vertically and share the same Y coordinate. |
HDR |
The HDR function supports automatic parsing and manual setting. The properties of 12G-SDI sources, DP1.2 sources and non-standard HDR sources can be manually set to HDR properties. Using the HDR function reduces the CX40 Pro load capacity by less than half if the CX40 Pro works with the CA50E, CA50C, or XA50 receiving card. For details, see theEthernet Port Load Capacitysection. |

Ethernet Port Load Capacity
When the CX40 Pro works with the CA50E, CA50C and XA50 receiving cards, the formula of calculating the load capacity per Ethernet port and the detailed parameters are as follows.
. 8bit: Load capacity × 24 × Frame rate < 5G × 0.75
. 10bit: Load capacity × 30 × Frame rate < 5G × 0.75
. 12bit: Load capacity × 36 × Frame rate < 5G × 0.75
