High Definition Television
HDTV, or High Definition Television is working its way into the mainstream with lower prices and continuing improvements over time. With up to 2 million pixels resolution, HDTV is a vast improvement over the 210,000 pixels we are used to with standard television. HDTV also comes in comes in different types such as plasma, LCD, or DLP (digital light processing). Each has it's own advantages and disadvantages. Before purchasing a HDTV, you should first make sure that high definition programming is available in your area, either over the air, cable, satellite, or recorded media. If it is only available over the air, it may be necessary to purchase an antenna made especially for HDTV due to it's highly directional properties. Try using your current standard antenna first though. Many standard antennas also have these directional properties. Some HDTV's do not have a tuner built into them, so you may have to get that from the cable or satellite company. Let's look at some pros and cons of differing HDTV types. But also keep in mind that the disadvantages diminish as the technology of each type advances. Plasma HDTV generally available in larger screen sizes (50 inches), but is also prone to "burn-in". This happens when something like a cable channel logo is constantly on screen and the image of it is burned into the screen permanently. Some computer games can also cause this. LCD screens are smaller than plasma and have more limited viewing angles, but are also not affected by burn-in. LCD HDTV is typically found in 32-42 inch screens. DLP or Digital Light Processing is a newer type of HDTV developed by Texas Instruments. It is less expensive than LCD and produces a better picture for screen action like watching sports. It also has a good life span, comparable to cathode ray tube televisions. Choosing the right HDTV depends on many things like budget, size of viewing room, angle of view, types of shows that you watch, etc. Take your time. With the new Japanese fiscal year coming up, you are sure to find some great deals on older models. |
