The Pros And Cons Of A Rear Projection Hdtv

Plasma and LCD televisions are the two most popular types of HD televisions. However, there is a third type which you can consider, as well, when shopping for an HDTV – the rear projection HDTV. Compared to front projection televisions, rear projection televisions consist of only one piece of equipment since they use built-in projectors to display images on the back of the screen.

Rear projection televisions used to be only CRT-based. In the past few years, though, LCD, LCoS and DLP rear projection technologies have emerged, which are all far superior in terms of picture quality and size. DLP televisions, which use a Digital Micromirror Device to display images, are considered the best of them all, and are therefore, usually the ones referred to when discussing the rear projection HDTV.

Indeed, the rear projection HDTV delivers great images, which it owes to several factors – its excellent contrast ratio, its impeccable shadow detail and most importantly, its outstanding color reproduction. In fact, the color quality offered by rear projection televisions comes very close to that of CRT televisions, and is particularly evident in the black levels, which appear as deep as can be, or even absolute.

Other great things about rear projection televisions is that they have very bright panels and are relatively easy to repair. They do not suffer from screen burn-in, as well, like Plasma televisions, nor do they suffer from the poor viewing angle and slow response time of LCD TVs. In fact, rear projection HDTVs have very fast response times, resulting in images that appear crisp and clear even when in motion.

LCD televisions have the upper edge in terms of longevity, though. While both rear projection and LCD televisions have a lamp-based technology and can last as long as their light does, the backlight of an LCD can last for up to 60,000 hours or more than seven years, and even longer in the case of LED backlighting. In comparison, the lamps of a rear projection television can only last 8,000 hours at most, which is even less than a year, which means you will need to replace the lamps often which can sum up to a hefty expense in the long run.

While rear projection TVs do not suffer from burn-in, they also have their own anomaly, which is called the rainbow effect. This means that there are times when you will see shadows of separate colors on the screen instead of a single, solid color, particularly in situations where white objects are set against a dark background. These shadows often appear in red, blue and green, although not everyone can see them.

The rear projection HDTV has other weak points, as well, such as its relatively high energy consumption and the occurrence of dead pixels or pixels which remain constant and unlit. The cooling fans and the color wheel can be noisy, too. Although rear projection televisions are much slimmer and lighter than they used to be, they are still bulky compared to LCD and Plasma televisions and are therefore, difficult to mount on the wall – something which many people like to do with their HDTV.

So, should you buy a rear projection HDTV? Now that you know how it works and what its pros and cons are, you should be able to answer this question more easily. If not, it’s alright. Just take your time deciding. After all, what is important is that you get the right type of HDTV of your home – whether it is a Plasma, LCD or rear projection HDTV.
