1. NovaStar CX40 Pro Introduction
The CX40 Pro works as a 4K display controller in the COEX series, and its job is to handle signal input, processing, and output for medium to large LED screens. It is a hardware unit that takes in multiple 4K formats, processes the video, and sends clean data to LED receiving cards through network ports or a 40G optical output.
The CX40 Pro works in two modes: All-in-One and Send-Only. In All-in-One mode, it handles both processing and sending. In Send-Only mode, it focuses on output while other processors handle the upstream work. This dual-mode design helps match different workflows, especially when the screen setup already uses several devices.
2. Main Inputs and Output Options
The CX40 Pro keeps its input and output layout simple and practical. The tables below show the main ports and what they are used for.
2.1 Input Options
| Input Type | Quantity | Notes |
| HDMI 2.0 | 2 | Supports 4K signals; each port includes a loop output |
| DP 1.2 | 1 | Handles common 4K formats from computers and media servers |
| 12G-SDI | 2 | Single-cable 4K SDI input; each port includes a loop output |
2.2 Output Options
| Output Type | Quantity | Notes |
| 5G Ethernet Ports | 6 | Standard output for most LED screen setups |
| 40G Optical Port | 1 | For long-distance runs or large high-bandwidth screens |
| SPDIF Audio | 1 | Extracts audio from the incoming signal |
2.3 Control and Communication
| Port | Purpose |
| Genlock Input (with loop through) | Used to sync the controller with other video devices |
| Ethernet Control Ports (x2) | For network control, configuration, and monitoring |
| Auxiliary Port | For additional control or system integration depending on the setup |
3. Key Processing Features
The CX40 Pro includes several processing tools that help it handle real 4K workloads.
- Three Independent 4K Layers
The controller supports three separate 4K layers. Each layer can be moved, resized, and ordered as needed.
- Scaling Modes
The unit offers multiple scaling modes, including point-to-point, custom scaling, fit-to-canvas, and full-screen. These modes help match the incoming signal to the LED screen without stretching or distortion.
- Color Tools
The CX40 Pro includes several color adjustment tools:
- 14-channel color correction
- Color curves
- 3D LUT support (17, 33, and 65 grid options)
These tools help match the screen to cameras, lighting, or other displays.
- HDR Support
The controller supports HDR10 and HLG. This gives LED screens a wider brightness and color range when using compatible content.
- Frame Rate and Low Latency
The CX40 Pro works with a wide range of frame rates, from 23.98 Hz up to 480 Hz. It also offers a low-latency mode for situations where delay needs to stay minimal.
- Dynamic Booster
This feature adjusts contrast and image brightness in real time. It helps maintain detail in bright and dark areas without adding extra noise.
- Other Tools
The controller also includes:
- Full gray-scale calibration
- 3D display support
- Frame multiplication and interpolation
- Shutter Fit, a tool for xR setups to reduce black lines in camera shots
4. NovaStar CX40 Pro Price
The price of the NovaStar CX40 Pro can vary depending on the project, the region, and the accessories that come with it.

This is the simplest way to see the current cost, compare options, and plan your project without any guesswork.
5. On-Device Control: The Front Touchscreen
The CX40 Pro has a 5.5-inch touchscreen on the front. You use it for quick checks and simple adjustments.
The home screen shows the basics:
- which input is active
- the screen resolution
- brightness level
- whether HDR or 3D is on
- sync status
- temperature
The menu is straightforward. You can change brightness, color temperature, or gamma. You can open a test pattern, or check the details of an input signal. Network settings are here too, so you can set an IP address or switch communication options like Art-Net or SNMP.
There’s also a simple maintenance area. It lets you run a quick diagnostic, check warnings, or export logs through the USB port. It’s useful when something looks off and you want to understand what’s happening without connecting a laptop.
6. Using VMP Software for Full Configuration
For full control, you use VMP (Vision Management Platform). This is the software NovaStar uses for the COEX series, including the CX40 Pro.
VMP is where you do the real setup work. Things like:
- mapping cabinets
- arranging layers
- choosing scaling modes
- adjusting color curves
- loading a 3D LUT
- checking cabinet status
It’s much easier to work on these settings when you can see the whole screen layout on your monitor instead of navigating through a small front panel.
You also use VMP when you want to manage HDR, fine-tune grayscale, or create and store presets. If the project has a large screen or several inputs that need to blend smoothly, VMP makes the workflow clearer.
Monitoring is another part of the software. You can see temperature, voltage, and running status in real time. This helps catch issues early, especially on long events.
7. NovaStar CX40 Pro Manual and Software Download
If you need the official documents for the CX40 Pro, you can download them directly here. They include the full user manual and the detailed specification file.
If you are working on a project and need other NovaStar tools — such as VMP, calibration files, or other software — you can find them on our NovaStar Software page. It’s the main place where all related tools and downloads are grouped together, so it saves time when you are looking for something specific.
