3.Key Features of NovaStar VX400
3.1 All-in-One Video Processor and LED Controller
The VX400 works as an all-in-one LED controller, combining a video processor and LED sending card in one device. Scaling, cropping, color adjustments, and signal distribution all happen in a single unit. For rental companies and integrators, this rental LED controller saves setup time. One power cable. One set of connections. One device to configure.
3.2 Supports Up to 2.6 Million Pixels
2.6 million pixels is suitable for many small and medium-sized LED projects. A P2.9 conference LED wall uses around 1.4 million pixels.
A P3.9 church LED screen uses about 2.3 million pixels. The NovaStar VX400 handles both. This gives you the flexibility to build wide stage backdrops or tall digital displays without changing controllers.
3.3 Multiple Video Inputs
The VX400 controller gives you several ways to connect sources. Two HDMI 1.3 inputs, including one HDMI loop output, support laptops, media players, and cameras. DVI supports older computer sources. SDI connects broadcast cameras. Two fiber ports send data over long distances. Users can work with laptops, PTZ cameras, broadcast equipment, and long-distance LED installations without extra converters.
3.4 Two Independent Layers
The VX400 supports two video layers: a main layer and a Picture-in-Picture (PIP) layer. You can show a full-screen presentation on the main layer while a small camera feed runs in the corner. Or display two sources side by side.
This is useful for live events and conferences. The main screen shows slides or video content. The PIP window shows the speaker on stage. The audience sees both at the same time. For churches, the main layer can display song lyrics while the PIP shows the pastor speaking. This makes the VX400 an excellent choice for conferences, churches, and live events where multiple video sources need to be shown at the same time.
3.5 Low Latency Processing
The NovaStar VX400 can reduce video latency to as low as 20 lines when Low Latency and Bypass mode are enabled, making it ideal for live camera feeds and stage events. When a speaker moves on stage, the image on the LED wall moves at the same time with no visible delay.
3.6 Pixel-Level Calibration
LED modules do not all shine at the same brightness or color. The VX400 supports pixel-level brightness and chroma calibration, adjusting each LED individually for a uniform image. This is especially valuable for fine-pitch LED displays in conference rooms and broadcast studios where viewers are close to the screen.
3.7 Three Working Modes
The VX400 has three operating modes. Video Controller mode is the standard setup for most projects. Fiber Converter mode sends signal through fiber ports to distant cabinets. Bypass mode passes signal through without processing, useful for daisy-chaining or troubleshooting. This flexibility reduces the need for additional hardware on different projects.
3.8 Backup Protection
The VX400 includes Ethernet backup between its 4 ports. If one fails, the signal routes through the others. Device backup is also supported — set up a second VX400 as a hot spare. For live events where downtime is not an option, this protection is essential.
4.NovaStar VX400 Applications
4.1 Rental LED Displays
Rental companies need controllers that are easy to transport and quick to set up. The compact size of this NovaStar LED controller makes it easy to pack in a flight case. The all-in-one design means less gear to carry and fewer connections to check during setup. Ten savable presets let you store configurations for different screen sizes and switch between them in seconds.
Typical rental projects include indoor stage backdrops, wedding LED walls, corporate events, and hotel ballroom setups. Whether it is a wedding, concert, or corporate event, the VX400 delivers stable performance with fast setup. For any rental job under 2.6 million pixels, this LED video processor is a reliable, cost-effective choice.
4.2 Stage LED Screens
On stage, reliability matters most. The VX400 backup features — Ethernet failover and device redundancy — keep the screen running during concerts and keynotes. Low latency keeps live camera feeds in sync with performers.
4.3 Church LED Walls
Churches use LED walls for worship lyrics, sermon outlines, and live video of the pastor. The PIP function shows the pastor in a small window while lyrics fill the main screen. HDMI inputs connect easily to presentation computers and cameras. Common applications include worship halls, prayer rooms, overflow areas, and live streaming.
4.4 Conference Rooms
Corporate conference rooms benefit from the VX400’s clean all-in-one design. The two-layer function supports hybrid meetings — remote participants on Microsoft Teams or Zoom on the main screen, the local presenter on the PIP. NovaLCT makes it easy for in-house AV teams to manage the display.
4.5 Retail LED Displays
Shopping malls, car showrooms, jewelry stores, and brand flagship stores run screens for hours every day. As a compact LED display controller, the VX400 handles digital signage, promotions, and in-store advertising reliably. Pixel-level calibration keeps the display sharp over months of continuous use.
4.6 Fine Pixel Pitch LED Displays
Fine-pitch screens (P1.9 and below) need precise calibration because viewers stand close. The VX400’s pixel-level brightness and chroma calibration makes these screens look their best — essential for corporate lobbies, broadcast studios, and premium retail.
