XGA - Extended Graphics Array is a standard computer display introduced in 1990 by IBM. The initial version of XGA built upon IBM's VGA, adding support for two resolutions, 800 × 600 pixels with high color . Used . and 1024 × 768 pixels with a palette of 256 colors. XGA-2 was developed later and with 1024 x 768 pixels with high color, and 1360 x 1024 with 16 colors. However, all XGA modes have an aspe. Used . ct ratio 4:3 rounded to 8 pixels....

Lumen - In physics, specifically photometry (optics), the lumen (symbol: lm) is the SI derived unit of luminous flux. It is the amount of light that falls on a unit spherical area at unit distance from a sour. Used . ce of one candela. In steradians this is equivalent to the amount of light that falls on a unit solid angle from a light source of one candela. Alternatively, one lumen is the total light pro. Used . duced by an isotropic light source of (1/4p) candelas. A 100 watt incandescent light bulb will output around 1500 lumens. ...
Hertz - A unit of measure for frequency generally applied to waveforms, one Hertz is equal to one cycle in one second. It is abbreviated Hz so that 100 Hz would be 100 cycles per second. However, the unit m. Used . ay be applied to periodic events other than waveforms like the second hand on a clock, which would cycle at 1 Hz, or a human heart that may beat at 1.2 Hz. Named after the German physicist H. Used . einrich Rudolf Hertz, the name was established in 1930, but did not replace the term cycles per second until the 1970s.
