Hi, I own one of these Synthagram 18.1 manufactured by Stereographics in fully working condition. One of the corners is got a little scratch, doesn't affect vision (I can send you pictures) Includes original software, interleaving software, etc. Tell me your offer if you're interested. It's a good product for developers, researchers, 3D entusiastics ... The 18.1-inch LCD SynthaGram 182-18 has a resolution of 1,280 x 1,024 pixels, a brightness of 235 cd / m², a contrast ratio of 300:1 and a horizontal and vertical viewing angle of 160 degrees. The image signals gives the display via DVI-I via an included 64-MB AGP graphics card. For the spatial representation required graphics drivers for Windows 98/ME/NT 4.0/2000 and XP and a Windows SDK included for custom application development. There is Linux and Unix support it yet. The SynthaGram 182-18 - the smallest of the four SynthaGram displays - did cost 3099, - €. in 2005/2006 Cheers!
