Both of them have LED-backlit TN LCD panels and a black exterior
There have been so many widescreen monitors lately that displays featuring a different shape come across as strange.The one that Dell has created, as revealed by PC Watch, is actually twice as odd as usual, since instead of the 4:3 aspect ratio (which used to be the most common), the panel has the 5:4 ratio.
Thus, it looks almost perfectly square in comparison to most of the other LCDs we've seen.
The name of the display is E1713S, the screen diagonal is 17 inches long, the native resolution is of 1280 x 1024 pixels, and the connection to PCs is done via D-Sub.
The 21.5-inch monitor is a common Full HD widescreen panel (1920 x 1080 pixels) with D-Sub plus DVI.
Everything else is the same on both screens: response time of 5ms, viewing angles of 160 degrees (horizontal and vertical), brightness of 250 cd/m2 and contrast ratio of 1,000:1. Both monitors sell for $150 / 116-150 Euro.
