This is known as the refresh rate.Ī complete screen image is called a frame. The display refreshes its screen several dozen times per second, typically 60Hz for LCD monitors and higher for CRT tubes. The display reads the color values from the frame buffer row-by-row, from left-to-right, top-to-bottom, and puts each of the values onto the screen. The GPU writes the color value into the frame buffer. The color values of the pixels are stored in a special part of graphics memory called frame buffer. The number of rows by columns of the rectangular grid is called the resolution of the display, which can range from 640x480 (VGA), 800圆00 (SVGA), 1024x768 (XGA) to 1920x1080 (FHD), or even higher. The number of color-bits per pixel is called the depth (or precision) of the display. This is different from the conventional 2D Cartesian coordinates, where y-axis is pointing upwards. The origin (0, 0) is located at the top-left corner, with x-axis pointing right and y-axis pointing down.

The position is expressed in terms of (x, y) coordinates. Color is expressed in RGB (Red-Green-Blue) components - typically 8 bits per component or 24 bits per pixel (or true color). A pixel has two properties: a color and a position. A raster is a 2D rectangular grid of pixels (or picture elements). Pixels and FrameĪll modern displays are raster-based. Modern day computer has dedicated Graphics Processing Unit (GPU) to produce images for the display, with its own graphics memory (or Video RAM or VRAM). Computer Graphics Hardware GPU (Graphics Processing Unit)
