lines of resolution

The vertical resolution (number of horizontal lines) on a TV or computer screen. The term typically is used with TVs; for example, HDTVs have 720 or 1,080 lines, while analog TVs used 525 or 625 lines, several of which were invisible between frames. VHS videotapes rendered only 240 to 260 lines.

Computer screen specifications are given in horizontal and vertical resolutions; for example, 1280x1024 and 1600x1200. Of course, digital TV screens also have two dimensions, such as 1280x720 and 1920x1080; however, only the lines of resolution are commonly referenced. See TVL, NTSC, DTV, 720p, 1080i and screen resolution.
