The sheer number of pixels that need to be juggled in a high-end installation can be staggering. The processor makes it possible
This is an illustrative article on the tasks a processor needs to excel at to pull off a first-rate installation. Mobile World Congress Barcelona put in place s a 22 megapixel, 98 foot wide, magnificent display, and somehow it all had to stay synchronized and picture-perfect.
A current 4K home screen is roughly 8 megapixels, so this installation is something approximating 3 state-of-the-art home LEDs and controlling the displays of all of them at once, keeping the different inputs in sync, and making the entire thing look as good as it can.
MWC used a Christie Spyder X80 multi-screen processor to do it, which can control up to 80 megapixels of display real estate. Eighty million pixels, sixty times a second. That is roughly five billion pixels, which at four bytes per pixel make a grand total of twenty gigabytes per second, every second, to process.
Sometimes it can be difficult to get a sense of the power necessary to provide a truly-world class display experience, but this is an illuminating article:
