The NovaStar VX400s is no longer in production. The listed alternative is the NovaStar VX400 Pro. Check the required inputs and receiving-card configuration before choosing a replacement.
The VX400s is an LED display video controller with four Gigabit Ethernet outputs and a total loading capacity of 2.3 million pixels. Its HDMI, DVI, SDI and analog inputs support existing media systems that use a mix of source connectors.
Image control for existing installations
Use the front-panel knob, buttons and LCD for screen configuration and source selection. The controller supports image scaling, seamless switching, fade-in/fade-out transitions and adjustable picture-in-picture (PIP). White-balance calibration, color-gamut mapping and NovaStar pixel-level calibration help configure the display’s image and color output.
PIP has source-pair restrictions: HDMI and DVI cannot be used together as main and PIP; the same restriction applies to VGA1 with VGA2 and CVBS1 with CVBS2. Check the input pair before planning a two-source layout.

Frequently Asked Questions
Is the VX400s still in production?
No. This listing identifies it as discontinued and points to the VX400 Pro as an alternative. Match the required input connectors and screen configuration before selecting a replacement.
How many pixels does the VX400s support?
Its four Gigabit Ethernet outputs have a total loading capacity of 2.3 million pixels. This is the combined capacity, not a per-port rating.
Can I connect VGA or component video sources?
Yes. The VX400s has two VGA inputs and one YPbPr input, each specified for resolutions up to 1080p at 60 Hz. It also has two PAL/NTSC composite-video inputs.
Why will some PIP source combinations not work?
The manufacturer’s source-conflict table excludes the HDMI/DVI, VGA1/VGA2 and CVBS1/CVBS2 pairs from simultaneous main-layer and PIP use. Select another supported source pair.
Which Ethernet port carries audio?
Only Ethernet output 1 supports audio output. Connect the multifunction card used for audio decoding to that port.
