PLE2207WS-B2 - 22" Iiyama E2207WS-B2 Black Widescreen LCD,1680x1050,2ms, DVI-D

As you’ll all likely know by now, DVI is the current standard for connection of a PC or other display generator to a digital display output. You’ll recognise the multi-pin connector and know that almost all modern LCD displays have the corresponding input connector, for feeding from your PC. But do you know how DVI works? This TekSpek seeks to teach you how.

There’s a lot more to High Definition than just having the ability to run your screen at the right resolution. With more than one type of connection available, and the thorny subject of signal encryption to contend with, just because your monitor and graphics are capable of 1,920 x 1,080 or better does not necessarily mean they will be able to display HDTV in all its glory.

Now shipping with all but the cheapest complete PCs are LCD monitors. Advances in display manufacturing and associated cost reductions with economies of scale have brought LCD monitors into the mainstream, shipping with budget systems that start at just £400. LCD monitors come in all shapes and sizes, have differing resolutions and inputs. The purpose of this TekSpek is to provide a basic understanding of how LCDs work, delineate their desirable features, and to offer basic buying advice.
