content: The screens are shipped in padded crates that hold 6 per crate. The shipping is through ground trucking. Each "panel" is 19.69" square. Each panel consists of 4 square quadrants. If we notice damage on a panel, we will replace the quadrants individually from the front without the need to remove an LED panel. You can remove the quadrants using a simple eyeglass flathead screwdriver. Once all the panels are connected, you then go into the color calibration phase, which essentially is you flashing all the panels with a configuration file. This configuration file comes from the screen manufacturer and is specific to the facility where the screens where manufactured. In the LED videowall world you want to use LED panels that were manufactured from the same facilty/date. Color matching panels that where manufactured at different facilties/dates is a PITA and requires much more than simply loading a config file.
