NovaStar VX400s LED video controller for legacy systems
The NovaStar VX400s combines video processing and LED display control, with four Gigabit Ethernet LED outputs and a published loading capacity of 2.3 million pixels. Its input set includes HDMI, DVI, 3G-SDI, VGA, composite video and component video, making the exact source connections important when reviewing an existing installation.
This page uses NovaStar’s LED Display Video Controller VX400s Specifications, Rev1.4.0, NS160100411. EagerLED’s existing listing marks this model as no longer in production. Use the information below to identify a legacy unit and prepare a configuration or replacement review.

VX400s connections and reference specifications
| Connection or parameter | Published details |
|---|---|
| LED output | 4 Gigabit Ethernet ports; 2.3 million pixels total |
| Digital video inputs | 1 HDMI 1.3, 1 DVI and 1 3G-SDI; SDI deinterlacing supported |
| Analog video inputs | 2 VGA, 2 CVBS and 1 YPbPr |
| Analog input formats | CVBS: PAL/NTSC; VGA and YPbPr: up to 1080p at 60 Hz |
| Loop and monitor outputs | SDI LOOP, DVI LOOP, VGA monitor and DVI monitor |
| Control connections | USB for PC communication; UART IN/OUT for device cascading |
| Power | 100–240 V AC, 50/60 Hz; overall consumption 35 W |
| Operating temperature | −20 to 60 °C (−4 to 140 °F) |
| Dimensions | 482.5 × 273.8 × 44.7 mm (19.00 × 10.78 × 1.76 in) |
| Weight in Rev1.4.0 | 3.09 kg (6.81 lb); confirm the actual unit and packing weight |
The loading figure is the total LED pixel capacity, not an input-resolution specification or a guarantee for every bit-depth and refresh-rate configuration. Rev1.4.0 lists 8-bit/10-bit video input and RGB, YCbCr 4:2:2 and YCbCr 4:4:4 formats. Check the source timing, processing settings, receiving cards and port map together.

Check the main-picture and PIP source pair
The VX400s supports an adjustable picture-in-picture image, but its connectors are not all independent for simultaneous main/PIP use. The Rev1.4.0 appendix excludes these pairs:
- HDMI together with DVI.
- VGA1 together with VGA2.
- CVBS1 together with CVBS2.
For example, an HDMI main picture and a DVI PIP picture are not an allowed pair in that conflict table. Check the intended two-source combination before planning an operator layout. Scaling and adjustable PIP size or position cannot remove an input-pair restriction.

Audio routing and control-port roles
HDMI audio input is listed alongside a separate audio input connector. Audio decoding through a multifunction card requires that card to connect to LED Ethernet port 1: Rev1.4.0 identifies only port 1 as supporting audio output. Include the decoding card and its cable route when checking a system.
Front-panel controls provide screen configuration without a computer for the documented workflow. The USB connector is nevertheless identified as a PC communication interface, while UART IN/OUT handles device cascading. Neither that USB description nor the presence of a connector establishes USB-drive media playback.

NovaStar VX400s selection questions
Is VX400 Pro a direct replacement for every VX400s installation?
No. EagerLED’s existing listing recommends considering the NovaStar VX400 Pro, but a replacement review must compare the actual inputs, PIP source pair, receiving cards, control files, audio routing and redundancy requirements. Legacy analog sources may require a different signal plan.
Can the loop or monitor outputs drive extra LED cabinets?
Use the four LED Ethernet outputs for the receiving-card path. SDI/DVI loop connections repeat signals, and VGA/DVI monitor connections serve monitoring; they do not add more LED Ethernet outputs or increase the published pixel capacity.
What should I provide before requesting a configuration check?
Send the exact model and hardware label, screen pixel dimensions, receiving-card model, saved configuration, port map and source formats. Add the intended main/PIP pair and any audio or backup requirements.
