57 Resolution The resolution of any display is the number of pixels that can be depicted on screen as specified by the number of horizontal rows against the number of vertical columns. The default VGA resolution of many video cards is capable of displaying 640 rows of pixels by 480 columns. The typical resolution of current displays is set to higher values, such as 1024x768 (XGA), 1280x1024 (SXGA), or 1600x1200 (UXGA). Saturation Refers to the intensity of a specific hue (color). A highly saturated hue is vivid and intense, whereas a less saturated hue appears more grey. A completely unsaturated color is grey. In terms of the RGB color model, a fully saturated color exists when you have 100% brightness in one of the three channels (say, red) and 0% in the two others (green and blue). Conversely, a fully desaturated color is one where all of the color values are the same. Saturation can therefore be thought of as the relative difference between the values of the channels. SCART SCART is an acronym for "Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs". SCART is an 21-pin connector used mainly in Europe for transferring analog audio and video signals between VCRs, DVD players, personal computers, and set-top boxes. It is sometimes referred to as Péritel or the Euroconnector. Scissor Mode A graphical load-balancing scheme where two graphics cards are used to render two halves of an image display. One graphics card renders the top half of the screen while the second graphics card renders the bottom half. This configuration offers a form of dynamic load balancing between the two cards as each only needs to render 3D object details on only half of the screen instead of the full screen at any one time. This type of graphical operation is only available in Radeon® CrossFire™ graphics cards running Microsoft® Direct 3D® and OpenGL® games or applications.
