Dell ST2310 review: Dell ST2310

The ST2310 earned a brightness score of 203 candelas per square meter (cd/m2)--lower than Dell's claimed 250 cd/m2 rating for the monitor and also lower than the Asus VH236H's 283 cd/m2.

We used the ST2310's movie preset to check out "Kill Bill Vol. 1" on DVD and a number of 1080p movie files from Microsoft's WMV HD Showcase. In both Kill Bill and the 1080p movies, we found that while the overall color of flesh tones was close to accurate, details like snow and white fabric were darker than we wanted and almost looked gray in comparison with the Samsung SyncMaster XL2370.

We looked at World of Warcraft and Unreal Tournament 3 and noticed no signs of input lag, streaking, or ghosting during fast movement; however, both games could have benefited from a brighter image, which the ST2310 couldn't deliver.

The optimal viewing angle for a monitor is usually directly in front of it, about a quarter of the screen's distance down from the top. At this angle, you're viewing the colors and gamma correction as they were intended. Most monitors are not made to be viewed at any other angle. Depending on its panel type, picture quality at nonoptimal angles varies. Most monitors use TN panels, which get overly bright or overly dark in parts of the screen when viewed from nonoptimal angles. The Dell ST2310 uses a TN panel, and when it's viewed from the sides or bottom, we perceived the screens to darken about 6 inches off from center. Of course, when viewed from the optimal angle, we had no problems.

In our power consumption tests, the Dell ST2310 had a wonderfully low On/Default power draw of 20.57 watts, compared with the Asus VH236H's 39.58 watts and the XL2370's 20.09 watts. The Dell's standby power is a low 0.52 watts. The Asus' was higher at 2.7 watts with the XL2370's at a lower 1.42 watts. Based on our formula, the ST2310 would cost a low $6.50 per year to run, compared with the Asus' $13.68 per year and the Samsung's $9.96.

Service and support
Dell backs the ST2310 with a solid warranty, including a three-year, parts-and-labor warranty covering the backlight. It also offers support through a 24-7 toll-free number, 24-7 Web chat, and Dell has a fast 24- to 48-hour e-mail turnaround time--a better package than most monitor vendors, which don't offer weekend support. Navigating Dell's Web site and finding the drivers, product manuals, and quick guides was simple and easy.
