SAN FRANCISCO (06/23/2000) - Six models on the chart cost under $400, so now is the time to find a bargain 19-incher. Of the three new monitors that debut this month, ViewSonic's GS790 climbs highest, thanks to its bold graphics and reasonable price. MGC's 997SN, at number six, offers impressive image quality, and Optiquest's Q95, number nine, is the cheapest, at $325. Models from ADI, Hitachi Data Systems Corp., and NEC Corp. fell short. Next month, we return to 17-inchers.
