512 to 600 lines at reduced vertical refresh rates (down to 50 Hz, and including e.g. 528, 544, 552, 560, 576-line), depending on individual monitor compatibility. For example, high resolution modes with square pixels are available at 768 × 576 or 704 × 528 in 16 colors, or medium-low resolution at 320 × 240 with 256 colors.
An Odyssey controller. The Odyssey consists of a black, white, and brown oblong box connected by wires to two rectangular controllers.The console connects to the television set through an included switch box, which allows the player to switch the television input between the Odyssey and the regular television input cable, and presents itself like a television channel on channel three or four ...
If these connections were to fail, the effect would be that an entire row or column of pixels would fail to activate. This causes a horizontal or vertical black line to appear on the display while the rest of the display would appear normal. The horizontal failure runs from edge to edge; the vertical failure runs from top-to-bottom.
The cursor for the Windows Command Prompt (appearing as an underscore at the end of the line). In most command-line interfaces or text editors, the text cursor, also known as a caret, [4] is an underscore, a solid rectangle, or a vertical line, which may be flashing or steady, indicating where text will be placed when entered (the insertion point).

The single fixed-screen mode used in first-generation (128k and 512k) Apple Mac computers, launched in 1984, with a monochrome 9" CRT integrated into the body of the computer. Used to display one of the first mass-market full-time GUIs, and one of the earliest non-interlaced default displays with more than 256 lines of vertical resolution.
A waveform monitor can be used to display the overall brightness of a television picture, or it can zoom in to show one or two individual lines of the video signal. It can also be used to visualize and observe special signals in the vertical blanking interval of a video signal, as well as the colorburst between each line of video.
Scan lines are important in representations of image data, because many image file formats have special rules for data at the end of a scan line. For example, there may be a rule that each scan line starts on a particular boundary (such as a byte or word; see for example BMP file format). This means that even otherwise compatible raster data ...
