Technological gadgets are created for special purposes. Most of the time, they are made up of a group of chips that process video, and they don’t have an operating system. Hardware video wall controllers are reliable and high-performing. Cost and lack of flexibility are disadvantages.
One example of a video wall controller that is really straightforward is a scaler with a single input and several outputs. It can take one video input and divide the image into pieces that match the displays on the video wall.
Most professional video walls also have a controller built in (sometimes called an integrated video matrix processor or splitter).
