LCD TVs with Screen Size 10 in-21 in priced Below $800 - Prices & Reviews
The number of pixels horizontally and vertically defines a TV's resolution in pixels or dots per inch (ppi or dpi). The greater the resolution, the more information or image you'll be able to view at once.
Response time is measured in milli-seconds (ms) and represents the time it takes for one pixel to go from active (black) to inactive (white) and back again. Needed to adapt to the constantly changing image on the screen. The lower, the better.
