When I started out as a custom installer back in 1998, a “big screen” was a 60-inch rear-projection TV, with high-end models available from the likes of Mitsubishi and Pioneer Elite. These were 4:3 aspect ratio, cathode ray tube-driven sets with 480i resolution, and they were physically hulking beasts weighing upwards of hundreds of pounds. Boy, have things changed over the past 20-plus years.
