I noticed the Prolight+sound 2026 news photo on the site.

Was the 4K60 video wall demo using a modular matrix processor, or a fixed 4x9 type processor?
We are comparing both options for a small demo room.
Both options can produce a 4K60 wall, and the choice really depends on how much you expect the room to grow.
A fixed 4K60 processor like the 4K60 HDMI 8×9 Seamless Matrix and Video Wall Processor is simpler and more cost-effective for a small demo room with a known layout.
A modular matrix processor (Modular Seamless Switching Videowall Processor) is card-based and scales up, which is better when you may add more screens or sources later. For a small demo room, the fixed type is usually the practical choice.
