Most TVs these days are LCD. Some manufacturers have completely phased out plasma. Why? Because while plasmas look better than LCDs in your home, they don’t win the brighter-bluer battle on the showroom floor.
Pause for a moment to reflect on this tragedy—this battle of who can make the most egregiously wrong image has actually caused a superior technology to fall out of favor with manufacturers. Plasmas lost by making movies look they way they’re supposed to.
How exactly is plasma superior? For the time being anyway, plasma TVs can render much darker black levels than even the best LCDs. This is the single most important factor affecting image quality in the home, where you are likely to watch movies with at least some of the lights off. It’s also something you just plain cannot judge in a brightly-lit store.
New paragraph for effect: If you are TV shopping, just about the worst thing you can do is go look at TVs in a store.
