LCD TVs that project from the back are the least expensive type of large TV. Some projection TVs have three cathode-ray picture tubes (CRTs), which are like smaller versions of the tubes used in regular TVs. The pictures from these small tubes are shown on the back of a 40-inch to 60-inch or bigger screen. This is why they are called "rear projection TVs." Other rear projection TVs don't have CRTs, but instead use LCD, digital light processing (DLP), or liquid crystal on silicon (LCoS) technology. High-tech rear projection TVs are thinner, lighter, and more expensive than similar CRT-based TVs, but they have better picture quality.
LCD TVs with rear projection are made by Hitachi, Mitsubishi, Panasonic, Philips, RCA, Samsung, Sony, and Toshiba, which are all well-known brands. The most popular models are HD-capable, and there are three main types of HD TVs.
So how do you choose the right LCD TV with rear projection for your needs?
First, think about how much space you have before you worry about the size of the screen. Most LCD TVs with rear projection have screens that are between 42 and well over 60 inches. You might be tempted to buy one of the biggest screens, which can be 70 inches or more, but first figure out how much floor space you have and plan to watch the TV from about 7 to 10 feet away for the best picture quality.
Also think about price and depth. Once you know how much space you have, you can decide whether size or price is more important. CRT TVs are floor-standing and have deep cabinets that roll on wheels. Some of them are as big as an armchair or a loveseat. Many LCD TVs with rear projection are tabletop models, or you can spend a few hundred dollars on a separate stand.
Then pay attention to picture quality. The best LCD TVs with rear projection give you a great picture with HD content and a good picture with DVDs and regular TV shows. LCD TVs with rear projection have much better picture quality than CRT TVs.
Check the angle of view as well. Some rear projection LCD TVs show a better picture when viewed from the side than older TVs did. This is important if several people will be watching your TV at the same time. Before you buy a certain model, step to the side or move up and down to see how the picture changes. When you move away from some LCD TVs with rear projection, the picture gets dimmer and less clear.
Once you've decided, you should think about whether you want a longer warranty on your rear projection LCD TV. Most of the time, extended warranties aren't worth it, but they might be for expensive TVs. LCD TVs with rear projection are expensive, so find out how much a service plan will cost. Find out if in-home service is covered and if you will get a new TV if your LCD TV with rear projection can't be fixed.
