I do not know the resolution of the device. > Kodak manufacturers such a system; it's called Datashow, and comprises an LCD screen that sits on top of an overhead projector, an infrared remote control, and a wall mounted power supply. The system's cabling provides a 'Y' connection to the output of a CGA type card, allowing your monitor to run at the same time, and a serial port connector for use with the supplied software. The software, called SHOWMAKER, is intended to facilitate the production of slide shows and help organize screen images. The remote control sends setup and control commands to the tablet and can also be used in conjunction with SHOWMAKER. We've been looking for an inexpensive alternative to the SONY or other video projection systems, which run $5K and up. The DATASHOW system is less than $1300 list. Screen resolution is 640 X 200 and the aspect ratio matches the IBM (1.3:1), so your circles come out as circles. The active area of the screen is about 6 X 8 inches, and the overall dimensions are 11.8 X 13 X 2.1". The display image is pretty good, with contrast, brightness, and centering adjustable with the remote. The image can also be inverted to give light on dark or dark on light displays. The nicest thing about it, versus the projectors, is that you can get a nice bright image that doesn't require a high gain screen or a pitch dark room. If you look closely, though there is some flickering of some of the pixels, but at distance the effect is not very noticeable.
