HP DreamColor LP2480zx review:

HP DreamColor LP2480zx

We tested the HP DreamColor LP2480zx using the Blu-ray version of "Avatar." In the movie, we saw accurate color, with a very slight green push when viewing in the Rec.709 preset. I want to reiterate how slight the green push is. It's hardly noticeable under normal circumstances and was only visible sitting next to the Dell Ultrasharp 2408WFP playing the same scene. When we switched to the Full preset, the green push was no longer noticeable. You could easily see dark image detail, such as braids in the hair of the Na'vi during a nighttime scene, on the LP2480zx.

Because of our intimate familiarity with World of Warcraft, it remains the best tool for us to use when judging color quality and vibrancy in games. The LP2480zx delivered a picture with a high level of color saturation in the default Full Preset. This gave the colors a vibrancy we've seen only on the likes of larger IPS monitors such as the Dell UltraSharp U2711 and NEC PA271W.

The LP2480zx delivered high-resolution photos with brilliant, deep, and accurate colors.

Viewing angle
The optimal viewing angle for a monitor is usually directly in front, about a quarter of the screen's distance down from the top. At this angle, you're viewing the colors as the manufacturer intended them to be viewed. 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 they are not viewed from optimal angles. On the other hand, IPS panels usually show only minimal color shifts with angle changes. The HP DreamColor LP2480zx has an IPS panel, and when it's viewed from the sides, we perceived the screen darkening about 15 inches off from center, which means it has more than twice as wide a viewing angle as a typical TN panel.

Recommended settings and use
For general use, viewing photos, and when playing games, we found the LP2480zx's Full preset to be the optimal picture setting. For watching movies, its Rec.709 preset was best, as long as the color temperature was adjusted to about 7,500k-8,000k.

As with most IPS-based monitors, HP gears its DreamColor LP2480zx mostly toward professional use, where accurate color reproduction is required; however, the monitor is also great for watching movies, playing games, viewing photos, and for general use.

Power consumption
The HP DreamColor LP2480zx gets a poor power consumption rating because of its Default/On energy use of 62.63 watts, compared with the NEC MultiSync PA271W's 87.79 watt use in the same test. In our Sleep/Standby test, the LP2480zx pulls 1.97 watts and the PA271W pulled a lower 1.17 watts. Based on our formula, the HP DreamColor LP2480zx would cost $20.05 a year to operate, compared with the PA271W's $27 a year.

Service and support
HP backs the DreamColor LP2480zx with a three-year, limited, parts-and-labor warranty that covers the backlight, which is the same great deal 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 and HP will charge you after that. HP's Web site offers Web chat and e-mail support that, according to the company, it replies to within an hour.
