The VX400 is NovaStar's new all-in-one controller that integrates video processing and video control into one box. It features 4 Ethernet ports and supports video controller, fiber converter and Bypass working modes. A VX400 unit can drive up to 2.6 million pixels, with the maximum output width and height up to 10,240 pixels and 8192 pixels respectively, which is ideal for ultra-wide and ultra-high LED screens.

The VX400 is capable of receiving a variety of video signals and processing high-resolution images. In addition, the device features stepless output scaling, low latency, pixel-level brightness and chroma calibration and more, to present you with an excellent image display experience.

What's more, the VX400 can work with NovaStar's supreme software NovaLCT and V-Can to greatly facilitate your infield operations and control, such as screen configuration, Ethernet port backup settings, layer management, preset management and firmware update.

Thanks to its powerful video processing and sending capabilities and other outstanding features, the VX400 can be widely used in applications such as medium and high-end rental, stage control systems and fine-pitch LED screens.
