So does that mean Sirius is better? Well, that depends. XM has some neat stuff too, like a bunch of cool XM Satellite Radio receivers and displays. They also have biggest broadcasting network right now, and are probably most likely to expand services significantly in near future. Overall, they are just about equal, and you are better off going with either of these services than any other.

LCD screens are made of several polarized glass panels, between which are liquid crystal molecules. An electric current is run through crystal molecules, changing their position in respect to glass. As light passes through molecules, these changes in angle result in different lightness/ darkness patterns that produce images on screen. There are usually three polarized glass panels, one with red pixels, blue, and green. This system also produced very accurate, vivid images, but angle is important. You may notice that best colors in an LCD display are seen straight-on.

Is DLP, LCD TV Screens better than other?

Simply put, that is a difficult question to answer. Unlike Plasma TV screens DLP and LCD last much are longer, and are considered to both have superior image quality. LCD screens tend to have slightly better contrast, with a larger range of black and white color shades. DLP, however, still has faster refresh rates than LCD (although LCD has been vastly improved in this area over last two years). This can have implications if you are really into high-action motion (sports, action movies), because movement may seem a little blurred with LCD at times. Also, you'll want to remember that in order for you to get best color out of your LCD, you have to sit right in front of it. LCD TVs also have a slightly shorter lifespan than DLPs, with only 45,000 to 60,000 hours compared to 75,000 hours or more. As far as price goes, LCD and DLP are still more expensive than Plasma, but like all things in time, their price has been coming down. And right now, DLP is slightly more expensive than LCD, but not by much. DLP, in our eyes, is best investment, at least for next few years.
