NovaStar VX400S All-in-One LED Video Processor

What is the NovaStar VX400s LED display controller?

The VX400s is a legacy all-in-one controller for an LED wall with an older AV rack. It accepts a supported source, fits the picture to the LED canvas and sends the finished image to receiving cards through four Ethernet outputs.

Its value is the source mix. It can keep HDMI, DVI, 3G-SDI, VGA, CVBS or component-video equipment connected without assuming the system is a modern 4K production rack. Start with the actual source and wall, then decide whether this controller still suits them.

VX400s key features

• Camera-friendly legacy input: 3G-SDI gives an installed stage or presentation rack a direct path from a planned HD camera feed.
• Source switching and PIP: build a main picture with one secondary image for a straightforward live presentation.
• Ten saved presets: recall a known layout instead of rebuilding a familiar screen before every event.
• Four-port wall support: use it only after the existing cabinet file and per-port loading have been checked.

VX400s specifications

VX400s inputs, loop-through and monitor outputs

Read the rear panel as a signal path, not as a long connector list. The selected source enters the VX400s. SDI or DVI can continue to another device through their loop-through connections. A VGA or DVI monitor output gives the operator a local place to check a source or setup result. The four Ethernet ports carry the mapped image to the LED wall.

Can the VX400s run your LED wall? Four ports and 2.3 million pixels

The four Ethernet outputs share a total LED load of up to 2.3 million pixels. Count the complete wall before dividing its cabinet chains across the ports. Four ports do not create four separate 2.3-million-pixel allowances.

Capacity is only one part of the fit check. The physical Ethernet order, the receiving-card configuration and the source format must also be right. A canvas can be inside the pixel limit and still show repeated or misplaced sections when the cabinet map does not match the wiring.

VX400s setup: when Quick Configuration is safe

Quick Configuration is for a regular screen made from cabinets with the same resolution. In that narrow case, the front panel can help bring up the wall quickly. It is not a safe shortcut for a curved layout, mixed cabinet sizes or a wall with an existing custom data path.

For a custom screen, keep the known receiving-card configuration file and use the documented configuration-file workflow. This separates the LED map from the video picture: first make sure every cabinet is in the right place, then choose the source and scaling setting.

VX400s scaling, PIP and source checks before a live show

Scaling decides whether the source fills the LED canvas, stays pixel-for-pixel or is placed in a chosen area. PIP adds one adjustable secondary image over the main picture. Those tools are useful for a presentation with a small camera, logo or confidence feed, but they do not make the VX400s a current multi-layer switcher.

If an image looks wrong, test in a fixed order. Show the controller test pattern first. Then confirm the cabinet map and Ethernet path. Only after the wall is known to be correct should the operator compare source resolution, frame rate, selected input and scaler setting. This avoids fixing a mapping fault by changing the laptop, or the reverse.

VX400s presets, backup planning and audio-output conditions

The controller can store ten user presets. A preset is useful when a venue returns to the same source and screen arrangement, but it should be saved only after the wall and input have been checked. The manual also documents primary and backup setup; test the selected recovery path with the real screen rather than assuming it is active.

Audio output has a specific condition: it uses Ethernet port 1 with the documented multifunction-card arrangement. Do not treat every Ethernet port as a general audio output. Confirm the installed receiving and multifunction hardware before including audio in the design.

VX400s applications for established LED and AV racks

These are support scenarios for a working legacy system. They are not reasons to choose VX400s for a new 4K or high-layer production build.

VX400s manual, datasheet and legacy support

Use files that name VX400s exactly. The official manual and datasheet below are safe references for ports, setup and limits. No exact VX400s firmware package was verified in the official download archive, so no guessed update file is offered.

Before any legacy change, save the working screen configuration and record the controller hardware version. For an unsupported source, a larger canvas or a current control workflow, compare a current processor instead of forcing a legacy update.

When an installed VX400s needs a current processor

Keep a VX400s when the wall fits its documented capacity, its existing legacy inputs are genuinely needed and the configuration is known to work. Start with a current processor when the source requires 4K or HDMI 2.0, the production needs more layers, or the project requires a current support path.

The right replacement starts with the source list, LED canvas, receiving cards, required layers and recovery plan. Review the current video processors against those facts instead of choosing the closest-looking model number.
