Instead of paying insane amounts for flat screens and installation, we can buy flat screens and install them on them for less money than renting them at an event (even with delivery). They are sturdy (like speaker stands). Mounting the bracket on the flat screen takes a while and is difficult to remove afterwards. They protrude on the sides so the coasters won't fit in a bag without detaching them. It could be spring loaded and didn't require disconnection. Not much if you're trying to save money by speaking at an event, no complaints.
