The '''Monochrome Display Adapter'''  ('''MDA''', also '''MDA card''', '''Monochrome Display and Printer Adapter''', '''MDPA''') is [[IBM]]'s standard [[video display card]] and [[computer display standard]] for the [[IBM PC]] introduced in 1981. The MDA does not have any [[pixel-addressable]] graphics modes, only a single [[monochrome]] [[text mode]] which can display 80&nbsp;columns by 25&nbsp;lines of high-resolution text characters or [[Semigraphics|symbols useful for drawing forms]].
