CX40 Pro 4K Controller for LED Displays
The NovaStar CX40 Pro brings source selection, screen control and image processing into the COEX platform. It works with VMP for cabinet layout and device management, while a 5.5-inch touch LCD provides local status and parameter controls. Its six 5Gbps Ethernet outputs have a maximum combined device load of 9 million pixels.
| Parameter | Specification |

| Power supply / consumption | 100–240 V AC, 50/60 Hz, 1.5 A / 105 W |
| Dimensions / net weight | 482.6 × 94.4 × 472.0 mm / 8.1 kg |
| Operating environment | −10°C to +45°C; 0–80% RH, non-condensing |

These values are from the linked specifications V1.0.0, dated January 12, 2023. The per-port loading table is documented for CA50E, CA50C and XA50 receiving cards. Check frame rate, bit depth, HDR requirements and the 9-million-pixel device limit together; port maxima cannot simply be added to claim a higher total capacity.
Input Formats and Loop Connections
At 8-bit, both HDMI inputs and DP 1.2 support RGB or YCbCr 4:4:4 and YCbCr 4:2:2 up to 4096 × 2160 at 60 Hz. HDMI 2.0-1 and DP 1.2 list 10/12-bit support; HDMI 2.0-2 lists 10-bit in the source-format table. For those higher-bit-depth RGB or YCbCr 4:4:4 formats, the table gives 4096 × 2160 at 30 Hz or 4096 × 1080 at 60 Hz. YCbCr 4:2:2 retains 4096 × 2160 at 60 Hz.
12G-SDI supports 10-bit YCbCr 4:2:2 up to 4096 × 2160 at 60 Hz. HDMI and DP input widths must be multiples of eight. The specification documents up to eight devices in an HDMI or SDI loop. Use the full source-format and connector tables in the PDF when planning custom resolutions.
Layers, Color Adjustment and VMP
All-In-One Controller mode enables up to three independent 4K layers with Z-order priority and custom, pixel-to-pixel or snap-to-canvas scaling. Send-Only Controller mode provides the sending workflow. VMP handles the cabinet topology and logical connections.
Color tools include Color Replacement, 14-channel color correction and RGBW curves. The specification also lists 17 × 17 × 17 .cube 3D LUT files. Dynamic Booster, full grayscale calibration and frame-rate adaptation have receiving-card and system requirements; they should not be assumed to work with every LED cabinet. See the function-limitations section of the original PDF.
Low Latency and Reserved Ports
The V1.0.1 manual specifies controller latency of 0 frames (less than 1 ms) in Send-Only mode and 1 frame in All-In-One mode for low-latency operation. These are controller figures, not a guarantee for the complete display chain. Genlock cannot be selected when low latency is enabled.
SPDIF audio output and AUX RS232 are marked reserved in the specification. USB 2.0 is documented for diagnostic export to an NTFS or FAT32 USB drive.
Frequently Asked Questions
How many pixels can the CX40 Pro control?
The maximum device load is 9 million pixels. Each 5Gbps Ethernet port also has a frame-rate and bit-depth limit; check both the individual port loads and the total screen load.
Does CX40 Pro support three 4K layers?
Yes. The specification lists up to three independent 4K layers, with priority adjustment and scaling, in All-In-One Controller mode.
Do both HDMI inputs support 12-bit video?
The V1.0.0 source-format table lists 10/12-bit for HDMI 2.0-1, but 10-bit for HDMI 2.0-2. Resolution and frame rate also depend on chroma sampling, so check the exact source format before use.
Can low latency and Genlock be enabled together?
No. The V1.0.1 manual states that Genlock cannot be used as the sync source when low latency is enabled.
Which software is used to configure CX40 Pro cabinets?
Use NovaStar VMP, the Vision Management Platform, for cabinet topology and logical screen connections. The original manual below explains the workflow and local controller settings.
