Something has changed in the world of projectors recently, especially at the medium level. Traditional projectors may be fairly clever in how they serve light to the screen, but they’ve been pretty dumb otherwise, requiring a video source, and some kind of external sound system plugged in.
Hence projectors have traditionally been permanently installed and cabled up — and not many are the modern living rooms in which that’s convenient these days, so that over the last decade we’ve seen bigscreen movie projection moving more and more into dedicated cinema rooms.
In a bid to appeal more widely, then, projector manufacturers have started building in extras. Some projectors have little sound systems, which can often seem pretty laughably small compared to the bigscreen pictures being produced. But more useful is the second evolution, which has seen first external media plonk-me-down visitor as it would if properly installed.
