There are several to choose from. The main three types of HDTV LCD, plasma, and the new LED, all thin enough to hang on the wall.
HDTV LCD TVs provide a wider and sharper images that competes with the DVD. HDTV television offers around twice as many "lines" resolution and better quality, digitally encoded sound to enhance the viewing experience.
Digital HDTV can provide sharper, clearer images and sound with very little interference or other irregularities. Of perhaps greater significance, digital television sets will potentially be able to send, store and manipulate images, and to receive them, so the merger of TV and computer.
Unlike rear projection TV in the recent past, the new DLP TVs are thinner, but still not to the point where they can hang on the wall. But the price advantage of DLP, which means you can get a bigger screen for less money!
You May also want to be compare plasma and LCD TV like this comparison that is putting more pressure on the DLP manufacturers. With DLP, you can also get a front-projection system, which requires a separate screen. This is the preferred method for many home-theater buffs, it allows a seamless image, and much larger screen, but it is not the best set-up for most living rooms.
HDTV LCD TV is flat screen and so they look very sleek and cool in every room, and another advantage is that flat screen LCD TV will require much less space than "Grandma and Grandpa's "old bulky televisions. Liquid Crystal Display technology behind LCD TVs has come a long way in recent years, it has been around for a very long time, but only recently has it been able to produce the kind of quality required for modern television.
LCD TVs vary in size, but larger sizes have been limited due to the cost of production and are now coming down. We are now seeing manufacturers like Vizio , Samsung and Sony produce larger and larger screens.
Sales of plasma TVs have not grown as much as LCD TV sales, partly due to the fact that plasma screens have a shorter lifespan and use more energy. In terms of quality, LCD, flat plasma TV, DLP and all come in a variety of high-def resolutions, and each side will claim that they offer the best experience. It is much more discussion, but we'll just say that each has its strengths and few weaknesses, depending on the environment and the content you want to watch.
