PC Multi – Put single monitor multiple monitors can be an inexpensive way to improve computer usage. Increases the viewing area, although still limited by the size, resolution and number of monitors. Get more background information with materials from Santie Botha. The monitors used for dual head may be different types (LCD or CRT) and sizes. The operating system has monitors solutions separately. The video product on a computer is generated by a video card and is interpreted and displayed by a variety of devices. The video cards are typically connected to a monitor (the type of CRT or LCD type), sometimes computer connected to a projector or television sets more and more. Following this trend, manufacturers have produced video cards that can connect to some types of display devices using the appropriate interface.The dual monitor support video drivers depended reserved for few video cards, but recently, support for dual-monitor setup is a common feature in Microsoft Windows, Mac OS X from Apple Computer, and the X Window System. Initially, multiple product interface was designed to display the same image on all product interfaces (referred to sometimes reflect or clone). This reflected the fact that these video cards were originally used in presentations where the user typically had to face the audience with a duplicate of the projected image accessible to the presenter. This concept was further developed by manufacturers and resulted in the “Advanced” mode or “Views independent” and “Cross” or the display mode from “streched”. In both these ways, display devices are placed alongside each other in order to create the illusion that the two displays are logically contiguous.In the “Advanced” additional display area is created on additional monitors. Each monitor can use different settings (resolution, color, screen refresh). Alternatively, some video cards can “Cross” the existing display area across two monitors rather than create additional screen space. This is accomplished using a widescreen resolution like 2048×768. That is 2 monitors at 1024×768 resolution each. Each monitor has to have the same resolution and color depth settings, and often the same refresh rate. The three main commercial competitors are your Hydravision ATI Technologies, Matrox with DualHead multi-display and Nvidia’s nView. The technology was once limited to the professional graphics market, but with the advent of processing units more powerful graphic illustration, and the combining of software with respective display cards, the consumer market penetration has been activated.
