Bij AGN Hardware kan je een review bekijken over een 21" monitor van Sony.
The GDM 500-PS is Sony's offering to the 21" market. The monitor has a Trinitron CRT (Cathode Ray Tube) and produces a great image. With a 19.8" viewable image size this unit was a tad bit smaller than the other models we looked at. The GDM 500-PS features a .26 dot pitch average (The GDM 500-PS vas a variable dot pitch of .25-.27) and a maximum refresh rate of 160Hz. Size wise, the Sony is a bit smaller than the Optiquest and sits impressively on the desktop. All 21" monitors seem big at first, and the Sony is no exception at 19.6" x 19.9" x 18.7". The unit is a little on the heavy side: 68.3Lbs.
