I dont disagree, it would be quite advatageous to have this standardised, but of course the display manufacturers have to add to the cost of thier equipment. So if the display is marketed for mainstream use, but some (smaller) market segments could use it for stereo it does not make economic sense for the manufacturer to add hardware and cost for a small (relatively) group, and jack up the price for everyone. >Shutter glasses with LCDs are a problem due to latencies of the LCD and >polarization issues (LCD has a polarizer in front of it).

From my recollection if you connect using DVI to a display device ALL the stereoscopic features on a quadro are disabled, becasue the refresh rate sync used to time the glasses is generated differently. (im not sure on this and could easily be wrong) The only way stereo works (is enabled) on a quadro is via the 15 pin vga analougue (with the dvi ti vga adaptor), but then you cant use the dual link dvi hi refresh capability of the new lcd monitors ?????? Hence the USB sync ????? Again i could be wrong on this, if some one knows this is not the case please correct me >That is possible, but these are really huge bricks, if I remember right. >I would also hesitate buying DELL machine because of past experience >with their "service", but that is another discussion. Well our expereince was not bad. They are big, especially if you get the 17inch screen version. And while i never would purchase a DELL desktop i would get a dell laptop or server.
