"All Lumacom models are configured in modules with the LED clusters arranged in a specialised matrix, physically composed of 90 pixels.

Each module then provides 900 pixels of 'virtual' full colour image resolution - which increases by the same as modules are linked vertically and horizontally.

A screen, 4 modules high by 4 modules wide, will deliver a 14,440-pixel resolution, even though only 1,440 pixels are physically present".
