The different TV types
Plasma- Plasma TVs offer a larger screen selection, a better contrast ratio, and do not blur as much when watching fast moving images, and have a wider viewing angle. If you are going to just be watching TV and movies and turning off your TV when you leave the room, I suggest getting a plasma as they tend to be cheaper than same size LCDs.
LCD-LCD TVs do not suffer the burn in (when a plasma is left on too long without the picture moving i.e. paused) which may result in the picture being burned into the TV. LCDs also do not heat up like plasmas and have nearly twice as long of a life span. If you want a TV 32” or less you will be forced to get a LCD as Plasma HDTVs do not go that small. If you plan on playing video games where you will pause a game for 10-15 minutes at a time I suggest getting a LCD as it is much less susceptible to the burn in factor.
Terms to know:
720p- 720 lines of color, progressive. This means that there are 720 lines of color every frame (1/60 second) and all the colors are displayed.
1080i- 1080 lines of color, interlaced. This means that there are 1080 lines of color but are only displayed every other frame. Half the colors are shown the first 1/30 of a second and the others are shown the next 1/30 of a second and so on.
1080p- 1080 lines of color, progressive. This means that there are 1080 lines of color every frame (1/60 second).
Note-Although it is very difficult to see the differences, when watching sporting events colors may seem blurred when watching programs that are interlaced
Burn in- When a static image is left on too long and leaves a permanent mark on the TV screen.
Contrast Ratio- The difference between the whitest white and the darkest black colors the TV can show. The better the contrast ratio the easier it is to see the picture.
DVI- Digital Visual Interface. It was the best quality visual input before HDMI but you need a separate cable for audio. With a converter, you can turn a DVI input into an extra HDMI input.
HDMI- High-Definition Multimedia Interface. Carries the best quality of and audio/visual input or cable then ever before. It combines audio and video to make less clutter.
