LED control systems are divided into synchronous and asynchronous control systems. Regardless of the control system, the display scene requires supporting software to configure the control system. NovaStar Technology has designed and developed an LED screen configuration tool, Nova LCT, based on the needs of different users.
This post will explore the core functions, applications, downloads, installation and use of NovaLCT software to provide an effective guide for your LED display project.
1. What is Nova LCT Software?
NovaLCT (NovaStar LED Configuration Tool) is a Windows-based software solution for configuring, calibrating, and monitoring LED display systems. It supports synchronous (live) and asynchronous (playback) control modes, making it ideal for a variety of applications – from concert stages, rental equipment to digital signage and fixed installations.
Why Nova LCT Software Stands Out?
● Comprehensive Tools: Combines setup, calibration, error detection, diagnostics, and remote monitoring in one platform.
● User-Friendly Interface: Automatically detects hardware; offers guided workflows and smart settings.
● High Reliability: Trusted as the industry benchmark for robust performance and extensive feature coverage.
● Continuous Improvement: Frequently updated with new features, including encryption, error logging, and cloud integration.
Who Needs Nova LCT?
LED Display Manufacturers & Integrators — for setup and calibration during production and installation.
Rental Companies & Technical Teams — for quick deployment, calibration, and fault recovery.
System Administrators — for long-term maintenance and remote diagnostics.
2. NovaLCT Key Functions
NovaStar NovaLCT is a comprehensive LED control platform that empowers AV integrators to configure LED video walls, ensure color/brightness accuracy, diagnose hardware issues, coordinate multi-screen layouts, automate alerts, and maintain performance via cloud oversight. It has an intuitive interface and robust features:
Function 1. Screen Configuration: Auto-detects sending cards/receiving cards, sets up panel layouts, manages redundancy, and supports image rotation and expansion.
Function 2. Brightness & Color Calibration: Nova LCT software offers sophisticated adjustment capabilities, including gamma, grayscale, and 18-bit+ settings. Supports online and batch calibration workflows.
Function 3. Diagnostics & Monitoring: Provides LED and bit error detection tools, test patterns, and fault diagnosis. NovaStar LCT supports environmental monitoring with sensors for temperature, humidity, and smoke.
Function 4. Multi-Screen Management: Easily configures large video walls by combining screens, synchronizing settings, and calibrating brightness across units.
Function 5. Multifunction Card Control: Enables relay control, timing schedules, external device triggering, and firmware updates.
Function 6. Cloud Integration: Works with NovaCare (VNNOX) for remote monitoring, status logs, and auto-updates.
3. Advanced Configuration Features
Nova LCT packs powerful advanced tools for fine-tuned LED display setups and robust performance:
① 18-bit / ClearView Mode: Enable ultra-high-bit-depth processing for ultra-smooth grayscales, reducing contouring artifacts.
② Low-Latency Option: Activate on both sending and receiving cards to reduce input-to-display delay by up to two frames—ideal for live video.
③ HDR Settings: Adjust peak brightness, HDR standard (PQ, HLG), and max brightness levels to ensure true-to-source visuals.
④ Image Booster Engine: Synchronizes with colorimeters to calibrate gamut (Rec.709, DCI-P3), grayscale precision, and dynamic contrast enhancement with 22-bit+ depth.
⑤ Multi-Screen Brightness Sync: Group screens for unified luminance control, whether uniform or across varied layouts.
⑥ Prestore Screen Options: Define default images for “no signal” or “no power” states, avoiding unwanted freeze-frames.
⑦ Automatic Redundancy: NovaLCT handles redundancy automatically when multiple ports or cards exist, enhancing system reliability.
⑧ Relay & External Control: Use multifunction card relays to schedule or trigger external hardware (lights, alarms) based on environmental or event-based conditions.
These advanced settings empower system integrators and AV technicians to achieve professional-grade visual fidelity, responsiveness, and operational excellence with Nova LCT.

6. Connecting & Configuring Guide
Connect Hardware
The software bridges content sources and LED panels through:
Sending Cards: Convert input signals (DVI/audio) into LED-readable formats, supporting resolutions up to 2048×668.
Receiving Cards: Distribute data to individual modules (e.g., NovaStar MRV560), handling 16–64 RGB groups per card.
Flexible Connectivity: Operate via Ethernet (recommended) or Wi-Fi Access Points (default password: 12345678).
Synchronous vs Asynchronous Control
Synchronous Mode: For live events/broadcasts, mirror computer screens onto LED displays in ≤60 FPS with near-zero latency using NovaStar ViPlex or NovaStudio.
Asynchronous Mode: Schedule content playback without continuous PC connection—ideal for repetitive ads or kiosks. Supports offline storage via SD cards.
Launch Nova LCT and Log In
Run the software and let it auto-detect connected devices.
Choose the correct user mode (usually “Advanced/Synchronous Control” or “Multimedia Player”) and log in. The default credentials are usually “admin“.
- Synchronous User: For real-time displays.
- Media Player Login: For asynchronous setups (credentials: admin/123456)
Screen Configuration
Choose Cloud Restore (if online) or Local Restore, or use the “One-Click Smart Settings” for auto-setup.
Send the configuration to receiving cards or player hardware and save to onboard flash memory.
Update Firmware or Drivers
Navigate to Tools → Firmware Update to refresh the sending/receiving card firmware.
Use the “Lightness” menu to adjust brightness, gamma, and color temperature.
Start Monitoring & Calibration
Open the Diagnostic Tools section later to access screen tests, LED error detection, bit error checks, and module-level controls.
Use the Monitoring features (sensors, environmental logs) under System Settings to set alerts or preventive maintenance routines.
7. Nova LCT vs Nova SmartLCT
NovaStar NovaLCT is the go-to tool in professional AV environments, offering full-featured LED wall configuration, redundancy setup, calibration, diagnostics, firmware control, and cloud connectivity. NovaStar SmartLCT, once popular for its ease-of-use and Mac/mobile compatibility, has become outdated and lacks advanced features compared to Nova LCT.
| Feature | NovaLCT | Nova SmartLCT |
| Target Users | Professional-use: manufacturers, integrators | Entry-level: end-users and basic setups |
| Platform Compatibility | Windows-only, robust enterprise-grade tool | Windows & Mac, mobile-capable (iOS) |
| Feature Depth | Full control: firmware, redundancy, calibration, multi-screen support | Streamlined: basic mapping, brightness, cabinet-level config |
| Professional Reliability | Industry standard, continuously updated since 2009; rig adoption worldwide | Limited updates; officially phased out with new VX series |
| Ease of Use | Steep learning curve; high configurability | Simpler interface; fast mapping for small jobs |
| Use Case Fit | Large-scale, high-precision video walls and rental systems | Simple indoor LED panels or proof-of-concept layouts |
For mission-critical displays, where precision, durability, and support matter, Nova LCT is the clear choice. Simple projects or initial demos may start with Nova SmartLCT, but professional installations inevitably require NovaStar LCT’s capabilities.
