Screen Size

CLOSE
TV screen size is always measured diagonally, from one corner to the opposite corner. So the screen of a 40-inch television, for example, measures 40 inches diagonally -- not 40 inches wide. Also, keep in mind that screen size measurements apply only to the screen itself and do not include the border areas outside the screen, so be sure to take overall size into account so that it fits your space or furniture. Aside from space limitations, the most important considerations when selecting TV size are viewing distance and personal viewing habits and preferences. So keep your room setup and family's viewing preferences in mind when selecting the right size to ensure an optimal viewing experience.

Display Resolution

CLOSE
A TV's display resolution refers to the number of pixels (essentially dots) that make up a TVs picture. TVs with a higher resolution have more, and therefore finer (smaller) pixels -- which create a sharper, more detailed picture. TV resolutions are described by a number (such as 720 or 1080) followed by the letter "i" or "p." The number describes how many horizontal rows of pixels the TV has, while the letter describes how those rows are drawn, or "scanned" -- either "interlaced" or "progressive." Traditional "interlaced scan" TVs draw all the odd rows, then all the even rows alternately. Newer "progressive scan" TVs draw all the rows in sequence. This type of scanning generally allows for a sharper image with a higher vertical resolution.

Refresh Rate

CLOSE
A TV's refresh rate, measured in hertz (Hz), determines how many times the screen is redrawn each second. Common TV refresh rates include 60, 120 and 240 Hz -- and some are even higher. In general, the higher the refresh rate, the less image flicker you will notice on the screen. TVs with higher refresh rates also display fast motion -- common to action movies and sports, for example -- much more smoothly than TVs with lower refresh rates.
