HP 2310e review:

HP 2310e

Viewing angle:
The optimal viewing angle for a monitor is usually directly in front, about a quarter of the way down from the top of the screen. At this angle, you're viewing the colors and gamma as the manufacturer intended. Most monitors are not made to be viewed at any other angle. Depending on the 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, making for inaccurate color representation. The HP 2310e uses a TN panel, and when it is viewed from the sides or bottom, we perceived the screen to darken about 6 inches off from center; typical for a TN.

Recommended settings and use:
During general use, we found the Text preset, with the contrast set to 62, to be the HP 2310e's optimal picture setting. For movies, games, and photo viewing, the custom preset, with the green attribute set to 195, was best. Still, the PX2370 had more vibrant and accurate color.

As with most TN-based monitors, the HP 2310e shouldn't be used if pinpoint-accurate color reproduction is required; however, the monitor is great for watching movies, playing games, casually viewing photos, and for general use. If you do have stringent color needs, we suggest you narrow your search to IPS- or PVA-based panels only. The more expensive Dell UltraSharp U2711 is a good place to start.

Also, the inclusion of a DisplayPort connection is a nice, useful extra for Eyefinity fans.

Power consumption:
The HP 2310e achieved good power consumption, with a Default/On power draw of 21.3 watts, compared with the Samsung PX2370's 25.01 watts in the same test. The consumption delta was higher in our Sleep/Standby test, with the 2310e drawing 0.86 watts and the PX2370 costing a lower 0.27 watts. With both monitors' center points calibrated to 200 candelas per square meter (cd/M2), the 2310e drew 19.7 watts, while the PX2370 drew a slightly higher 19.9 watts. Based on our formula, the HP 2310e would cost $6.95 per year to run, compared with the Samsung PX2370's $7.65 per year.

Service and support
HP backs the 2310e with a three-year, limited parts-and-labor warranty that covers the backlight, which is the same very good deal that other vendors, such as Dell, provide. HP includes free shipping labels and in-home service, as well as support through its 24-7 toll-free number. Just be aware that the free service ends after one year, so HP will charge you after that. HP's Web site offers Web chat and e-mail support; according to the company, it replies within an hour.
