The NovaStar VX4S-N is an all-in-one LED video controller with image processing and four Gigabit Ethernet outputs. It loads up to 2,300,000 pixels and accepts both digital and analog video sources, including HDMI, DisplayPort, DVI, 3G-SDI, VGA and CVBS.
Screen control and source switching
Front-panel quick configuration supports basic screen setup without computer configuration software. Image scaling, seamless switching, fade effects and adjustable picture-in-picture (PIP) help arrange content for a live display. The TAKE button switches between the main layer and PIP when PIP is enabled. Multiple units can be connected for an image mosaic.
The controller supports white-balance calibration, color-gamut mapping and pixel-level calibration. A DVI monitoring output lets an operator check the output image. For audio decoding through a multifunction card, connect that card to Ethernet output 1.

Input-format note: the connector section lists up to 1920 × 1200 at 60 Hz, while the PDF’s video-source table recommends 1920 × 1080 at 60 Hz for its listed color formats. HDMI and DP support the listed 8-bit and 10-bit formats; 12-bit and YCbCr 4:2:0 are not supported in that table. Match the source format to the detailed PDF when configuring an existing unit.

Frequently Asked Questions
Is the NovaStar VX4S-N still available?
This listing is marked discontinued and no longer available. Contact sales with the screen resolution, receiving-card model and required inputs to discuss an alternative; do not assume another controller has the same connectors or configuration.
How many pixels can the VX4S-N control?
Its four Gigabit Ethernet outputs support up to 2,300,000 pixels in total. The maximum width is 3840 pixels and the maximum height is 1920 pixels, subject to the total loading limit.
Can HDMI and DVI be displayed together in PIP?
No. The manufacturer’s PIP source-conflict table excludes HDMI and DVI as the simultaneous main-layer/PIP pair. Other different-source pairs shown in that table are supported.
Can the USB Type-A port play video from a USB drive?
The VX4S-N specification identifies USB Type-A as an output connector for linking another device. It does not list USB media playback. Use one of the documented video inputs for content.
Where can I download the VX4S-N specifications?
The PDF in the Specification download section contains the connector details, source-format limits, dimensions and PIP source-conflict table. Check the VX4S-N model name when using it for an existing installation.
