  • The inputs of the VX4S include CVBS×2, VGA×2, DVI×1, HDMI×1 , DP×1 and SDI×1. They support input resolution up to 1920×1200@60Hz; the input images of VX4S can be zoomed point-to-point according to the screen resolution.

  • Provide seamless high-speed switching and fade-in/ fade-out effect so as to strengthen and display picture demonstration of professional quality.

  • The location and size of PIP can both beadjusted, which can be controlled at will.

  • Adopt the NovaStar G4 engine; the screen is stable and flicker free without
    scanning lines; the images are exquisite and have a good sense of depth.

  • Can implement white balance calibration and color gamut mapping based on different features of LEDs used by screens to ensure reproduction of true colors.

  • HDMI/external audio input.

  • 10bit / 8bit HD video source;

  • The loading capacity: 2.3 million pixels.

  • Support multiple controller montage for loading huge screen.

  • Support NovaStar's new-generation point-by-point calibration technology; the calibration is fast and efficient.

  • Computer software for system configuration is not necessary. The system can be configured using one knob and one button. All operations can be done in a few steps. That's what we call Easy Screen Configuration!

  • Adopt an innovative architecture to implement smart configuration; the
    screen debugging can be completed within several minutes; greatly shorten the preparation time on the stage.

  • An intuitive LCD display interface and clear button light hint simplify the control of the system.


  • The maximum loading capacity of video output is 3.9 million pixels.

  • 7 input connectors: 2 × 3G-SDI, 2 × HDMI1.3, 2 × DVI, 1 × USB.

  • Supports 3 ×layers and 1 ×OSD.

  • Supports quick and advanced screen configurations.

  • Switches the PVW to PGM by pressing only the TAKE button in the switcher mode.

  • Supports PGM preview in the switcher mode.

  • Supports adjustment of input resolutions and backup of input source.

  • Supports brightness adjustment of the screen loaded by the VX6s.

  • Multiple VX6s units can be cascaded.

  • Automatically scales the image to fit the whole screen.

  • The maximum video output width is 4096 pixels.

  • A total of 16 user presets can be created and saved as templates. The templates can be used directly and conveniently.

  • Any HDMI or DVI input source can be used as the synchronization signal to achieve vertical synchronization of output.

  • Features an intuitive OLED screen and clear button indicator lights in the front panel, simplifying system control and operation.


    • The inputs of the VX4U include CVBS×2, VGA×2, DVI×1, HDMI×1 , DP×1 and USB×1. The supported input resolution is up to 1920×1200@60Hz. The input images of VX4U can be zoomed point-to-point according to the resolution of LED display.
