VigilLink GeoBox G904 4-channel UHD Video Wall

The G904 steps the G902's 2-channel design up to four outputs, pairing two independent processing modules - each with its own set of HDMI inputs and two HDMI outputs - in a single chassis for a 4-screen wall built from up to 4K sources at 10-bit, 4:4:4 color. Every channel supports the same 4096x2160/7680x2160 input range and BT.2020/HDR10 color handling as the G902, just doubled in output count.

Independent per-channel color adjustment and bezel compensation carry over from the G902 as well, so a 4-screen wall assembled from mismatched panels can still be tuned to look uniform. Daisy-chain loop-outs on each channel allow linking additional G9-series units for walls larger than four screens, and the box is controlled via IR, RS-232, USB, or Ethernet like the rest of the G-series.
