Mac OS X natively reads EDID information and programs such as SwitchResX [4] or DisplayConfigX [5] can display the information as well as use it to define custom resolutions. E-EDID was introduced at the same time as E-DDC , which supports multiple extensions blocks and deprecated EDID version 2.0 structure (it can be incorporated in E-EDID as ...
G-Sync is a proprietary adaptive sync technology developed by Nvidia aimed primarily at eliminating screen tearing and the need for software alternatives such as Vsync. [1] G-Sync eliminates screen tearing by allowing a video display's refresh rate to adapt to the frame rate of the outputting device (graphics card/integrated graphics) rather than the outputting device adapting to the display ...
As dictated by the ICC system, the profile connection space in ColorSync is the CIE XYZ color space.All image input and output devices (scanners, printers, displays) have to be characterized by providing an ICC profile that defines how their color information is to be interpreted relative to this reference color space.
Lastly, benchmarking a video card or rendering engine generally implies that the hardware and software render the display as fast as possible, without regard to monitor capabilities or resultant video tearing. Otherwise, the monitor and video card throttle the benchmarking program, causing invalid results.
Within the monitor, the four signals are interpreted to drive the red, green and blue color guns. With respect to the RGBI color model described above, the monitor would translate the digital four-bit color number to some seven distinctive analog voltages in the range from 0.0 to 1.0 for each gun.

Once the beam of the monitor has reached the edge of the screen, it is switched off, and the deflection circuit voltages (or currents) are returned to the values they had for the other edge of the screen; this would have the effect of retracing the screen in the opposite direction, so the beam is turned off during this time.
Apple's manufacture history of CRT displays began in 1980, starting with the Monitor /// that was introduced alongside and matched the Apple III business computer. It was a 12″ monochrome (green) screen that could display 80×24 text characters and any type of graphics, however it suffered from a very slow phosphor refresh that resulted in a "ghosting" video effect.
This monitor as well as others that could be manually switched between these two sync rates were known as dual-scan displays. [ 6 ] The NEC Multisync was released in 1985 for use with the IBM PC, supporting a wide range of sync frequencies including those for CGA, EGA, various extended forms of those standards marketed by third party vendors ...
