2x2 Video Wall Controller

The GGrozza 2x2 video wall controller accepts one HDMI or DVI input and distributes it across four HDMI outputs to create a tiled display. It supports RS232 control and 5.1-channel audio via optical fibre for integrated installations.

4K Input to 1080p Output

Inputs handle 3840x2160 at 30 Hz and 1920x1080 at up to 60 Hz while outputs are fixed at 1920x1080 60 Hz. The processor divides the source into four blocks so each display shows a quarter of the original image at full HD resolution.

HDMI 1.4 Bandwidth Limit

HDMI 1.4 and HDCP 1.4 restrict the pipeline to 4K 30 Hz on the input side and 1080p 60 Hz on the output side. Rotation of 180 degrees is available in seven of the eight splicing modes but only on outputs one and two, and only when both input and output remain at or below 1080p 60 Hz.

How can I confirm the 4K@30Hz input is being split correctly across the four 1080p60 outputs?
