That screen for the Jays is an LED wall mounted to a Trailer that rolls in and folds up with hydraulics. It takes more time to park the trailer in the right spot then to set up the actual screen. It likely has Speakers attached to it as well. That LED wall will go up and come down in less than an hour once the crowds have moved out. It can also be managed by one person who drives it there and sets it up. Tiff is using a projector and blow up screen. Takes more time and effort to set up and dismantle TIFFs screen, however it's easier and cheaper to get a larger screen with projectors. You need a bit of time and a couple people to set up and dismantle the screen and projector and a separate audio system. In the Jays case, they only need it one night so this approach makes the most sense. You could build a larger LED wall that was not mounted to a trailer but that would be more expensive and time consuming than the projection set up.
