NovaStar VX4S-N LED video controller
The NovaStar VX4S-N combines LED display control and video processing, with four Gigabit Ethernet outputs and a published loading capacity of 2.3 million pixels. It accepts digital and analog sources, supports scaling and offers an adjustable picture-in-picture (PIP) layout.

VX4S-N input and output specifications
| Item | Specification |
|---|---|
| LED output | 4 Gigabit Ethernet ports; up to 2,300,000 pixels total |
| Maximum output dimensions | 3840 pixels wide or 1920 pixels high, within the total loading limit |
| 3G-SDI | 1 input with loop; up to 1920 × 1080 at 60 Hz; progressive/interlaced input and deinterlacing supported |
| DVI | 1 input with loop; VESA input up to 1920 × 1200 at 60 Hz; HDCP 1.4 and interlaced input support |
| HDMI 1.3 | 1 input; up to 1920 × 1200 at 60 Hz; HDCP 1.4 and interlaced input support |
| DP 1.1 | 1 input; up to 1920 × 1200 at 60 Hz; HDCP 1.3 and interlaced input support |
| Custom DVI / HDMI / DP timings | Maximum width: 3840 pixels at 3840 × 652 at 60 Hz; maximum height: 1920 pixels at 1246 × 1920 at 60 Hz |
| VGA / CVBS | 1 VGA, up to 1920 × 1200 at 60 Hz; 1 CVBS for PAL/NTSC |
| Audio input | 1 external audio connector |
| Audio through LED output | Only Ethernet port 1 supports audio output; connect the audio-decoding multifunction card to port 1 |
| DVI OUT | 1 output for monitoring |
| Network control | 1 Ethernet connection for PC/network communication |
| USB control | 1 Type-B for PC control/cascade input; 1 Type-A for cascade output |
| Video input bit depth | 8-bit and 10-bit support listed |
Custom input timings and LED output capacity are different limits. A maximum width of 3840 pixels does not establish support for a native 3840 × 2160 LED wall. Likewise, do not combine the maximum width and height into one canvas without checking total pixels and port mapping.
PIP, switching and screen configuration
VX4S-N supports adjustable PIP size and position, seamless switching and fade transitions. Its quick screen-configuration function is intended to simplify setup, but an existing installation still requires the correct module settings and receiving-card configuration.
The listed image-processing functions include the Nova G4 engine, white-balance calibration, color-gamut mapping and pixel-level calibration. Multiple units can be linked for image mosaics. Confirm the complete source, controller and receiving-card combination instead of assuming a fixed setup time or guaranteed image quality for every display.
VX4S-N frequently asked questions
Is VX4S-N still available to order?
The original listing says it is out of production and no longer available. Contact EagerLED to check the current supply position or discuss a replacement suited to the existing screen.
Can one VX4S-N drive a 1920 × 1080 LED screen?
That matrix contains 2,073,600 pixels, below the listed 2.3-million-pixel total. This calculation alone does not approve the installation: check the cabinet mapping, output-port loading and receiving cards.
Can the USB ports play videos from a flash drive?
The documented USB connections on this listing are for PC control and linking devices. They do not establish USB media-playback support. Use the specified video inputs and confirm any required playback function separately.
Which Ethernet output should carry audio?
Only Ethernet port 1 is listed for audio output. When using a multifunction card to decode audio, connect that card to port 1 and verify the complete audio path.
What information is needed to choose a replacement?
Provide the LED screen pixel dimensions, receiving-card model, source connectors and timings, required PIP layout, audio path and a copy of the working configuration. Include controller photos and firmware details.
