I was struck by how user friendly the interface was to manage the Evertz EFX Video Wall System. Behind the scenes is the 9700DVT-18×18 Digital Video Tiler with the ability to accept up to 18 live real time video inputs and the ability to drive up to 18 displays inside a single 1RU package. For video walls that are larger than 18 displays, an unlimited number of 9700DVT-18×18 can be stacked together to create the largest video walls in the market.
