ViewSonic VP231WB 23

One clear business advantage is that the screen can pivot on its axis. Portrait viewing yields a better picture of full document pages, Web sites, and some specialized business applications. Pivoting the screen also makes it easier to reach the four USB 2.0 ports in the back. The VP231wb comes with Perfect Pivot, ViewSonic's version of Portrait Displays' $40 Pivot Pro software; if you're bargain-shopping for a large wide-screen monitor and plan to use pivot, take this add-on into account.

The VP231wb has only analog and digital PC inputs--no composite, component, or S-Video inputs--so we tested it with its digital input. When we watched a scene from our test movie DVD in full-screen mode, images looked sharp and colors rich, but subtle shadows and highlights in a black velvet cloak didn't come through. Video quality improved at the smaller sizes of picture-in-picture displays; but even at these small sizes, a little motion artifacting was evident. ViewSonic rates the VP231wb's response time at 12 milliseconds, which is its intergray (also called gray-to-gray) response time; its rise-and-fall (or black-to-white) response time is 16 milliseconds. In any case, the monitor displayed smoother video than did the Samsung 243t (its closest LCD competitor for overall image quality), though it couldn't match the motion display quality of a good CRT.

Upshot: The ViewSonic VP231wb displays gorgeous still images and reasonably good moving images; the pivoting screen and included pivot software could tip the balance in this wide-screen monitor's favor.
