HP 2311xi review: HP 2311xi

In our Dark Screen test, the monitor showed obvious but not egregious clouding on the right side of the screen.

Text: Black text on white looked clear, without any obvious color tint problems. Fonts were clearly visible down to a 6.8 size.

The monitor displayed each preset with a slight green tint; however, through some deep OSD customization I was able to minimize the green look. It didn't abolish it completely, but definitely reduced its effect. While each preset is tailored well to its intended function, here are my recommended settings if the green is too oppressive.

Movies: I tested the HP 2311xi using the Blu-ray version of "Avatar." The Movie preset provides a good experience, displaying high contrast and a vibrant look; however, there was a definite green-tint push. This is especially apparent in faces with light complexions. Instead of seeing a healthy dose of red, the faces have a slightly greenish look to them.

Turning on Dynamic Contrast deepens black levels even more, but unfortunately simultaneously crushes dark gray, so I don't recommend doing so.

Games: When evaluating the look of games on a monitor, the two most important features to consider are vibrancy and color. If the monitor can display games with a bright and vibrant cleanness, this goes a long way. If colors also pop with fullness and depth, games can usually look great.

Dragon Age II on the HP 2311xi in the Gaming preset had high vibrancy with colors that popped suitably. However, like the Movie preset, the dreaded sickly greenish tint reared its ugly head, but can be alleviated with the settings I recommend above.

To test refresh rate, I used DisplayMate's motion graphics tests and stared at a number of colored blocks as they moved around the screen at various speeds. The 2311xi displayed slightly more streaking than the Samsung SyncMaster PX2370 during the test.

Photos: For faces and light-colored hair, the 2311xi's colors sometimes dip ever so slightly into a greenish hue compared with the PX2370, but the bright colors of clothing and environments pop vibrantly.

Viewing angle
The optimal viewing angle for a monitor is usually from directly in front, about a quarter of the screen's distance down from the top. At this angle, you're viewing colors as the manufacturer intended. Most monitors aren't designed to be viewed at any other angle. Depending on the monitor's panel type, picture quality at suboptimal angles varies. Most monitors use TN panels, which get overly bright or overly dark in parts of the screen when not viewed from optimal angles.

The 2311xi uses an e-IPS panel and sports viewing angles; much wider than what TN panels usually display, especially when viewed from the bottom. Also images on the 2311xi retained their integrity from the sides better than the TN-based PX2370.

Power consumption
The HP 2311xi achieved good power consumption, with a Default/On power draw of 24.8 watts. The Samsung SyncMaster PX2370 drew a similar 25.01 watts in the same test.

In our Sleep/Standby test, the HP 2311xi drew 0.48 watt and the PX2370 pulled a lower 0.29 watt. Based on our formula, the 2311xi would incur the same cost as the PX2370, with a per-year pull of $7.73 per year, compared with the PX2370's $7.65 per year.

Conclusion

Sure, the HP 2311xi's In-Plane Switching panel affords it wider viewing angles than what most 23 inchers enjoy, but that's not what makes it a compelling potential purchase. It's the fact that it has this powerful IPS panel with a price starting at a low $240. That's cheaper than even some Twisted Nematic (TN) monitors, which usually sport pretty low prices.

With great performance in movies and games and a good number of connection options, the 2311xi is a great general-purpose monitor with enough extras and price that makes it stand above most 23-inch monitors.
