GamePC heeft een vergelijking gepost van 4 21-inchers: de Mitsubishi 2020, Sony GDM 500PS, Cornerstone P1700 en Viewsonic P815. Jammer dat de Iiyama Vision Mastor Pro 510 er niet bij zit, want die monitor lijkt op dit moment erg populair te zijn vanwege z'n lage prijs en goede specs. Hier maar een stukje over de Mitsubishi, die samen met de Sony als beste bevonden werd:
Image quality of the 2020u is near perfect, but is edged out by the Sony monitor by a very small margin. At the same 1600x1200 native resolution, the 2020u had single pixel ghosting on icons, whereas the Sony didn't, and that was the only difference that we saw. The 2020u is debatably more attractive to the eye, since the monitor has a more "curved" look than the other monitors in the roundup. The 2020u also has a great USB setup, which consists of four USB ports (two upstream, two downstream), and a signal downstream port on the bottom/front/left hand side of the monitor, perfect for plugging in a shiny new USB mouse, which I found to be a very useful feature, instead of having to move around your desk trying to get to the USB port on the back of the monitor.
