DVI(Digital Visual Interface) Industrial Displays

DVI is a popular form of video interface technology made to maximize the quality of flat panel LCD monitors and modern video graphics cards. It is a replacement for the P&D Plug & Display standard, and a step up from the digital-only DFP format for older flat panels. DVI cables are becoming increasingly popular with video card manufacturers, and most cards nowadays include both a VGA and a DVI output port. DVI FORMATS There are three types of DVI connections: DVI-Digital, DVI-Analog, and DVI-Integrated (Digital & Analog) DVI-D - True Digital Video DVI-A - High-Res Analog DVI-I - The Best of Both Worlds

Display Resolution Industrial Displays
Source:Wikipedia
The display resolution of a digital television or display typically refers to the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by all different factors in cathode ray tube (CRT) and flat panel or projection displays using fixed picture-element (pixel) arrays. One use of the term "display resolution" applies to fixed-pixel-array displays such as plasma display panels (PDPs), liquid crystal displays (LCDs), digital light processing (DLP) projectors, or similar technologies, and is simply the physical number of columns and rows of pixels creating the display (e.g., 1280×1024). A consequence of having a fixed grid display is that for multiformat video inputs all displays need a "scaling-engine" (a digital video processor that includes a memory array) to match the incoming picture format to the display. Note that the use of the word resolution here is misleading. The term "display resolution" is usually used to mean pixel dimensions (e.g., 1280×1024), which does not tell anything about the resolution of the display on which the image is actually formed.
