this have the cool factor with a trio of laser and single scanning mirror , but there be pro and con , most significantly poor video quality . the most significant advantage be that the image be always in focus , even on uneven surface . the flip side of this be that because the overall picture diverge greater than the laser beam , when the picture be large , the space between the scan line be annoyingly visible . hopefully this will be address as this technology evolve . the picture be also dimmer than dlp -lrb- at least compare to the Optoma pk201 -rrb- and not as sharp . the speckled image can be annoying , though that might just be a personal choice . when I first turn on the showwx + , I be amaze and very pleased , especially at short to mid-range distance up to 5 - 6 foot . not until I get the Optoma do I realize I do not need to settle for the dim and dispersed picture . the final straw , besides my showwx + show a defect with ghost image , be that there be no automatic aspect ratio setting . the showwx + require you to choose 4:3 or 16:9 whichever fit best the current video . it be annoy to have to keep switching and not every video fit one of these preset aspect ratio . I assume this be either lazy programming or anal product design . despite these flaw , I fully intend to give the ShowWX , or some other projector that embed the next version of the PicoP , another look whenever that come to market . apparently Microvision be develop a hd picop for use with third-party projector , but will not produce a hd projector of they own . for now , I be very happy with the Optoma pk201 , which have the add feature of a Micro sd card slot .
