The TRS-80 Color Computer (also known as Coco) two color 256×192 graphic mode allows the display of four colors by exploiting NTSC artifacts. It is not possible to reliably display 256 dots across the screen due to the limitations of the NTSC signal and the phase relationship between the graphics chip clock and colorburst frequency. Using the ...
Color 6 is treated specially; normally, color 6 would become dark yellow, as seen to the left, but in order to achieve a more pleasing brown tone, special circuitry in most RGBI monitors, starting with the IBM 5153 color display, [11] makes an exception for color 6 and changes its hue from dark yellow to brown by reducing the analogue green ...
The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
The white screen of death that appears on Dell computers. A White Screen of Death appears on several other operating systems, content management systems, [6] and on some BIOS, such as from Dell. It can be seen on iOS 7, and also when a white iPhone 5 or later or a white 5th generation iPod Touch screen freezes. Everything on the screen but the ...
The Color Bar signal is generated with unconventionally slow rise and fall time value to facilitate video level control and monitor color adjustments of HDTV and SDTV equipment. Digital test images generated following the RP 219:2002 specifications and adapted to perfectly fit 114 standard and non-standard resolutions for both 16bpp and 8bpp ...
A BIOS Color Attribute is an 8 bit value where the low 4 bits represent the character color and the high 4 bits represent the background color. The name comes from the fact that these colors are used in BIOS interrupts, specifically INT 10h, the video interrupt. When writing text to the screen, a BIOS color attribute is used to designate the ...
Color matching software, such as Apple's ColorSync Utility for MacOS, measures a monitor's color temperature and then adjusts its settings accordingly. This enables on-screen color to more closely match printed color. Common monitor color temperatures, along with matching standard illuminants in parentheses, are as follows: 5000 K (CIE D50)
The horseshoe-shaped surrounding grey area represents colors humans can see, but that the monitor cannot show. Supplementary colors can widen the color gamut of a display, since it is no longer limited to the interior of a triangle formed by three primaries at its corners, e.g. the CIE 1931 color space.
