Can I just use normal TVs for a video wall?
No. Consumer sets meet at 20–30 mm of frame instead of 0.88–3.5 mm, cannot be colour-matched as an array, are rated for about 16 hours a day rather than 24/7, cannot be driven as one canvas, and must be dismounted for service.
What sizes do video wall panels come in?
46", 49", 55" and 65". 55" is the most specified size because it balances canvas area against panel count and cost.
What is a video wall controller and do I need one?
The controller receives your sources and decides what appears where across the array — full canvas, windowed, or per panel. Any wall beyond a simple mirrored 2×2 needs one. Modular controllers accept cards, so the system grows with your source count instead of being replaced.
Do video walls need a special wall?
They need a structurally sound wall and enough depth for the mount and service access. Where the structure cannot be loaded — glass, partition or heritage walls — a free-standing stand section carries the array instead.
