Some Things You Need To Know About TVs

If you are thinking of buying a new TV, it may seem like a headache at first. There is so much information to consider when making an investment as costly as this, especially during economic trouble. Here are some things you should look out for when buying your new HDTV.

If you see a TV that has the numbers 1080, it means that the resolution has a value of 1920 x 1080 pixels. Interlaced scanning has been used in televisions since 1941. Images are drawn vertically through different lines and are done quick enough to fool the brain into thinking it is seeing a whole image. Some TV enthusiasts and experts claim to see the difference between a TV with interlaced and progressive scanning. The p stands for progressive, which means that each frame you see on TV is transmitted as a whole. A 1080p TV is an advantage in the way that all video displayed is in high definition without the need for converting down, which affects the picture quality negatively.

All the newer TVs utilize progressive scanning in some way. A 60Hz refresh rate means that there are 60 frames of video given in a second. The newer HDTVs are usually double that speed at 120Hz, and that means that 120 frames of video are shown in a second’s time, producing better picture quality. Each frame of video is only shown for half the time than it used to at 60Hz, so the movement on video is much smoother. This can especially be noticed when watching a fast-paced movie, sports game, or even video game.

Analog TVs had an aspect ratio of 4:3, which means that the TV was shaped more like a square. Using inches solely as an example, a TV would measure 48" wide, or 4 feet, and 36" high, or 3 feet. Compare that to a HDTV, which uses a 16:9 ratio. The reason behind using this ratio is so that watching on a HDTV gives you a true theatre-like experience. Wide screen TVs allow you to see more things that occur on the outside than you would normally see on a standard analog TV.

Choosing between an LCD and plasma is really up to preference at this point. Each one has its advantages and disadvantages. LCD TVs, for one, are relatively cheaper and lighter, but its lack of ability to display darker colors and saturation hinder its performance. Since LCD, or liquid crystal display, projects its images by the use of a backlight that is shined onto liquid crystal that is pressed between two glasses, some light manages to shine through the cracks.
