G-405 Quad channel UHD video wall controller with 4k loop out
G-405 is 4 channel video wall controller. It was designed with two processing modules. Each processing module consists of 4 input and two HDMI output ports. It can supports 4k/2k input source and show single or dual contents across 4 LCDs. Users can easily build a 4k/8K video wall with G-405.  Largest video wall can be up to 15x15 from single video source. It can crop image for creative video wall. The image can be up/down flip for easy use of conventional TV or monitors to compensate dimensions difference at top and bottom bezels. Pixel by pixel precise position and bezel alignment. 4K/2K Loop out port for easy daisy chain connection among multiple unit cascade. System can be controlled via remote control or RS232. No PC or special software is required.
  • Max input: 4k/2k @30Hz and 3840x1080 @60Hz with 4:4:4 full sampling
  • Connectivity: any signal source from PC, media player, PlayStation, Xbox, Blue Ray...
  • Structure: each G-405 consists of two processing modules. Each display module consists of 4 input and two output ports. It can build a video wall using 4 LCDs with single or dual display contents. Multiple units can build larger video wall without number limitation.
  • True 4k/2K display: User can build true 4k/2k display using one G-405 and 4x LCDs or 8k/4k display with 4x G-405 and 16 FHD LCDs.
  • Projector: Serve as image splitter and set overlap pixel for projector edge blending.
  • Position shift: image shift pixel by pixel at H&V position up to 900 pixels for irregular creative video wall.
  • LCD: Work with any high end or low cost LCD without matrix control. Conventional TV and monitor can be used at top/down flip position for bezel balance.
  • Video switcher: Multiple input ports to serve as video switcher.
  • 4k HDMI loop out port: for daisy chain connection in multiple unit cascade application.
  • Simplify high resolution video wall system. No image lag or synchronization issue.
  • Processor: 10-bits high end video processor with 3D motion adaptive de-interlace, low angle smooth algorithm and 3:2/2:2 film mode processing.
  • Aspect ratio adjustment: flexible, able to display 2.35:1 movie in 16:9 screen without blanking borders.
  • Arbitrary image cropping (zoom in/out)
  • Work with other GeoBox for PIP/POP and image rotation/flip.
  • Portrait video wall can be achieved using 90 degrees rotation image.
  • Capable of multi-view display.
  • Frame lock: to synchronize all displays with input signal without frame tear.
  • Custom display setting: save up to 5 custom settings.
  • Control: IR remote controller and RS232.
  • No PC or software is required.
