G408 8x CH video wall controller

Quick Overview

GeoBox G408 is 8 channel 4k/60 fps Video Wall controller. It is designed with two processing modules. Each processing module consists of 1x HDMI 2.0 input, 1x HDMI 2.0 loop-out port for daisy chain connection and 4 synchronized HDMI outputs. It can serve as one eight channel video wall controller or two quad channel video wall controllers. Each output has independent image rotation/flip, scaling, cropping and color adjustment to allow great freedom in creating video wall with variable display scales and styles. Support pixel to pixel true 8k/4k video wall through 4x 4k input sources and two units of G408.

It is pure hardware, standalone system and easy-of-use. All operations can be executed through IR remote controller, USB, RS232 or Ethernet. No additional PC or appropriate software is required in the setup.
