content: The refresh rate is over 2000Hz. Each screen has a power input, data input, power output, data output. All of the screens are daisy chained together, with limitations. For this job, we drew power from 208-volt circuits, which each individually would power up to 20 panels daisychained together. So we used 20 separate 208-volt circuits to power this screen.  The data (which holds the video info) must first pass through an LED controller box. For this job, we used 6 LED controller boxes, each of which handled the video for approximately 65 individual panels. Before the LED controller boxes is a device called the Christie Spyder X20 1608, which handles the splitting/combining of the video input/outputs to achieve the 5120x1280 pixel-to-pixel resolution match.
