Some older arcade games that had a tall vertical and short horizontal are displayed in pillarbox even on 4:3 televisions. Some early sound films made between 1928 and 1931, such as Sunrise: A Song of Two Humans, were released in even narrower formats such as 1.20:1 to make room for the sound-on-film track on then-standard film stock.

The MDA was based on the IBM System/23 Datamaster's display system, [2] and was intended to support business and word processing use with its sharp, high-resolution characters. Each character is rendered in a box of 9 × 14 pixels, of which 7 × 11 depicts the character itself and the other pixels provide space between character columns and ...
The plus–minus sign or plus-or-minus sign (±) and the complementary minus-or-plus sign (∓) are symbols with broadly similar multiple meanings. In mathematics , the ± sign generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction .
0 8 4 12 2 10 6 14 1 9 5 13 3 11 7 15 Each permutation in this sequence can be generated by concatenating two sequences of numbers: the previous permutation, with its values doubled, and the same sequence with each value increased by one.
The plus and minus symbols are used to show the sign of a number. In mathematics, the sign of a real number is its property of being either positive, negative, or 0.Depending on local conventions, zero may be considered as having its own unique sign, having no sign, or having both positive and negative sign.
EGA: 15.7 kHz (CGA compatible mode) or 21.8 kHz horizontal scan, 60 Hz vertical scan; VGA: 31.5 kHz horizontal scan, 60 or 70 Hz vertical scan. No support for CGA/EGA timings. CGA/EGA resolutions are transmitted to the monitor at VGA compatible timings. XGA: 35.5 kHz horizontal scan, 87 Hz (43.5 Hz interlaced) vertical scan (plus VGA modes)
Plus–minus sign (±), a mathematical symbol which can mean either plus (+) or minus (−), or can indicate the uncertainty of a measurement or statistic; Plus–minus (sports), a sports statistic used to measure a player's impact on the game; Plus–minus method, a geophysical method to interpret seismic refraction profiles
A value of 1 becomes 254, 2 of 253, and so on: n is swapped for r - n, for r levels of brightness. This is occasionally called a ones' complement . If the source image is of middle brightness, reverse video can be difficult to see, 127 becomes 128 for example, which is only one level of brightness different.
