This VX400 listing is discontinued. The listed alternative is the NovaStar VX400 Pro; confirm the input, receiving-card and control requirements before replacement.
The NovaStar VX400 combines video processing and LED control, with four Gigabit Ethernet outputs driving up to 2.6 million pixels. Video controller, fiber converter and Bypass modes cover different signal-routing needs. Two layers provide main-picture and PIP layouts, with up to ten presets for recall.
Video inputs and optical connections
The VX400 accepts two HDMI 1.3 sources, DVI and 3G-SDI. HDMI 1.3-1, DVI and SDI have loop outputs. OPT 1 adapts to video input or sending output according to the connected device, while OPT 2 copies or backs up the four Ethernet outputs. The HDMI output supports monitoring or video output with adjustable resolution.
SuperView III processing provides scaling, full-screen display and input cropping. Control is available through the front panel, NovaLCT and V-Can. An external light sensor can support automatic brightness adjustment; pixel-level brightness and chroma calibration works with NovaLCT and NovaStar calibration software.

Document revision note: the original linked V1.0.0 PDF lists 1.6 A and 28 W, and describes HDMI/DVI interlaced input support. The manufacturer’s V1.2.0 specification lists 1.5 A and 35 W and states that HDMI/DVI interlaced inputs are not supported. These revisions are shown explicitly rather than treating the two document versions as interchangeable.
Configuration limits
The documented 20-line delay from input to receiving card requires both low latency and Bypass mode. Cabinets must align at the top of the enclosing rectangle. Only the main layer can use the optical mosaic source, and PIP is unavailable while that source is in use. Image mosaic disables full-screen scaling and pixel-to-pixel display of the layer. Main-layer fade is unavailable when PIP is open or the main layer uses the mosaic source.

Frequently Asked Questions
Is the VX400 the same as the VX400 Pro?
No. Both list 2.6-million-pixel output capacity, but the VX400 has two layers and HDMI 1.3 inputs. The VX400 Pro offers HDMI 2.0 4K60 input, USB playback and six 2K layer resources. Confirm the required feature set before choosing a replacement.
Does the VX400 support PIP with an optical mosaic source?
No. Only the main layer can use the mosaic source. When it does, the PIP layer cannot be opened.
How is the 20-line latency achieved?
The specification requires low latency and Bypass mode together. Cabinets loaded by the Ethernet ports must align at the top of the enclosing rectangle.
Can I send audio through any Ethernet output?
For multifunction-card audio decoding, use Ethernet output 1 or 2. The specification identifies those two ports for audio output.
Why does the old PDF list 28 W instead of 35 W?
The retained V1.0.0 PDF lists 28 W and 1.6 A. NovaStar revised the power/current information in later documentation; V1.2.0 lists 35 W and 1.5 A. Check the document version and the actual unit’s label when planning an installation.
