- Plasma televisions come as Enhanced Definition TV (EDTV), with a resolution of 852x480 and the Higher Definition TV (HDTV), featuring a native resolution of 1024x768. Plasma televisions have a high widescreen aspect ratio - the ratio between the width and height of the screen. As plasma televisions do not use any electron beams like the conventional ones, they are immune to the effects of magnetic fields. They offer a wider viewing angle and accurate image reproduction. Plasma televisions are slim and space-saving and can even be hung on a wall. Moreover, most of the plasma televisions come with a flat screen which eliminates edge distortion.
- When shopping for a DLP television, it is important to learn as much as you can about the new technology, inadditionto shopping around for the best possible price. When shopping for a new DLP TV, it is important to look carefully at the kind of tuner the unit uses. Many modern television sets are designed to be multisystem devices, meaning that not only are they capable of reading the NTSC signal used in North America and Japan, but they will also be able to deal with competing standards such as PAL and SECAM. This can be an important consideration, so it is important to make sure you understand these various formats and how they affect you as an end user.
- The US government has approved a subsidy coupon program to help people purchase DTV tuners to facilitate the analog-to-digital transition so existing analog TV sets can continue to be used for broadcast digital DTV. For that purpose, Congress approved a fund of $1.5 billion dollars, with an initial allocation of $990 million dollars to subsidize up to two $40 coupons per household. The coupons became available in January 2008 and can be requested by consumers until March 2009, to use them toward the purchase of two DTV tuners.
- While there have been many technological innovations in the world television in the last couple of decades, perhaps none have captured the attention and excitement of the public at large quite like the LCD TV. When these flat screen displays first showed up on the market, they were prohibitively expensive for all the but the wealthiest consumers, but as is the case with many facets of technology, the prices of these LCD displays have come down quite a bit over the last couple of years.
