Acer X193Wb 19" Widescreen Monitor

Screen size (diagonal): TV screens are measured diagonally, from corner to corner. HDTVs often look smaller than SDTVs with the same screen size because of the wider 16:9 aspect ratio.

Widescreen: Older displays are often referred to by a ratio: 4:3. I.e., they’re 4 parts wide and 3 parts tall. Today’s widescreen displays are 16:9, allowing us to see movies with narrower or even no black bars on the top and bottom of the picture.

Maximum resolution: Resolution tells you the number of pixels horizontally and vertically on a display (e.g.1280x960); the more dots, the better the picture.

Static contrast ratio: Contrast ratio is the difference between the brightest and darkest a TV can get. Static contrast ratio is a measurement that more closely reproduces real-world conditions. Dynamic contrast should only be used as a comparison within a brand.

Response time: Some monitors have physical pixels that move to pass and block light. The ability to do this quickly (8 milliseconds and less) plays a part in reducing blurring when displaying fast motion.

DVI (Digital Video Interface): This is a digital interface for connecting a video source, such as a DVD player, to an HDTV or HD monitor. DVI has the necessary bandwidth for uncompressed, HD digital video.
