sync-ing to a frequency that is higher than the phosphor triplets can resolve leads to moire patterns (often masked due to inter pixel spill) which cause colour shifts and gamma errors, ie bad bad bad for photo editing." Rob, True enough for horizontal resolution. But as my earlier post pointed out, there are no phosphor triplets in the vertical axis, but continuous phosphor stripes. As for your second comment: "I don't believe that this is likely, I doubt that the screen can actually resolve 200dpi, it might sync at this rate but not resolve it. Any URLS, models, specs?" As you'll see in the URLs below, the T221 is an active-matrix liquid crystal display. http://www-3.ibm.com/solutions/lifesciences/solutions/medical.html http://www-3.ibm.com/solutions/lifesciences/pdf/T221_brochure-final.pdf It uses amorphous silicon technology, which has allowed a breakthrough in addressable-transistor resolution. Before the T221, amorphous silicon was used chiefly in military displays, such as head-up displays. For more on this breakthrough, see http://www.techtv.com/news/print/0,23102,3372077,00.html In 1994, as a contractor for the Congressional Office of Technology Assessment (OTA), I coauthored a report on flat-panel display technologies: http://www.wws.princeton.edu/cgi-bin/byteserv.prl/~ota/disk1/1995/9505/95050 4.PDF It's been like a pleasant dream to see several "military only" display technologies enter the civilian sector, some (like conventional AM-LCDs) even becoming near-commodities.
