Most any large-scale LED project is going to be estimated with a processor. What are they?
Essentially, think of this device as a traffic cop that directs each and every pixel on what color to display at a given moment. It is integral to the display, and every custom LED panel requires one.
We cannot think of this purchase as a TV purchase. Televisions come with all the buttons and features built-in. Video displays require every piece to be built as necessary. If every large-scale LED were 1920x1080 and 16:9, processors would be the same as those in mass-market televisions. Some companies, like Video Scoreboard, leverage this cost savings to make screens more affordable for smaller organizations.
But custom videoboards don't adhere to an industry standard shape and resolution—- your display will be a one-off that will not match the settings, resolution or aspect ratio of anything else. So the signal you plug in to it requires its own custom processor.
No video display works without a processor. It’s the only way to get a signal input to the pixels of your display. AND The processor you receive as part of your videoboard setup will be very picky about what signal it will accept.
In order to be certain that all the disparate video sources you will throw at your display can be normalized to work with your unique resolution and aspect ration, you will likely need a scaler, which we will discuss next.
