Once we had the screen properly set up, the 23ET83V-W performed well in most of our image tests. We found no stuck or dead pixels, and colors were uniform. Text was legible even at small point sizes, and photographs looked good, although making out details in shadowy areas of the image was hard. In some of the DisplayMate gray-level test patterns, we were unable to see differences in the first few gray-level patches. Switching the display's Black Level control setting from its default Low to High resolved the issue.
The LG's viewing angle wasn't quite as stellar as that of other IPS screens we've seen. Color shifts weren't an issue, but at extreme angles it was harder to see what was on screen. This minor drawback is probably attributable to the touchscreen coating.
Speaking of the touchscreen, the 23ET83V-W performed admirably in that regard. It was responsive and accurate, and we had no problems using Windows 8 touch gestures or closing windows and choosing menu items on the Windows 8 desktop.
The LG Flatron 23ET83V-W is a capable touchscreen display. Its viewing angle isn't as wide as that of most IPS screens we've tested, but is still very good. Its controls were a bit of a hassle to use, and we needed to make adjustments to the black-level settings to help the display look its best. While those are admittedly minor grievances, the monitor's lack of ergonomic agility could reduce the amount of time you end up using its touch capabilities.
LG Flatron 23ET83V-W, $550 (street price)
Limited ergonomic flexibility
Black levels require adjustment
This is a very good display, but its controls are more difficult to use than they should be, and its viewing angles aren't as good as other IPS monitors we've evaluated.
Viewsonic's TD2340 display is built like a tank, weighing a hefty 20.4 pounds. It features a 23-inch, LED-backlit, IPS panel that delivers a resolution of 1920 by 1080 pixels, and it supports 10 touch points.
The TD2340 has a heavy-duty, dual-hinged base that offers a few inches of height adjustment, the ability to pivot into portrait mode, and even the option to tilt the display down so that it sits completely flat like a tabletop. At a height of 6 inches above the desk, however, the flat orientation seems like an awkward way to work. The best position we found for typing directly on screen using the touch keyboard was tilting the panel back to a 45-degree angle and lifting the bottom-front edge a couple of inches off the desk. This position allowed us to type on the screen without reaching as far, while still being able to keep our physical keyboard and mouse in front of us.
