Asus MS238H review:

Asus MS238H

Viewing angle: The optimal viewing angle for a monitor is usually directly in front of the display, about a quarter of the screen's distance down from the top. At this angle, you're viewing the colors as they were intended by the manufacturer. Most monitors are not made to be viewed at any other angle. Depending on its panel type, its 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 Asus MS238H uses a TN panel, and when it's viewed from the sides, we perceived the screen to darken about 6 inches off from center; a typical viewing angle limit for a TN-based monitor. Since the monitor is constantly tilted 10 degrees back, when viewed from below, the display had a much shallower viewing angle that darkens about 2 inches below the optimal eye line. At its default settings, the PX2370 had a typical viewing angle threshold; however, it has a few extra features that improve viewing from specific angles. The Asus MS238H doesn't include these features.

Recommended settings and use
During general use, watching movies, and playing games, we found the Standard preset to be the MS238H's optimal picture setting with the color temp set to Warm or sRGB and the contrast adjusted to 74. When editing photos, you should set the monitor's Skin Tone option to Reddish. This reduces the slight green tint, making faces in photos look more natural as a result.

As with most TN-based monitors, the Asus MS238H shouldn't be used if accurate color reproduction is required; however, the monitor is good for watching movies, playing games, 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 Dell UltraSharp U2711 is a good place to start.

Power consumption
The Asus MS238H has a good power consumption level in our tests, with a Default/On power draw of 26.59 watts, compared with the PX2370's 25.01 watts consumption in the same test. The monitor's consumption delta was much higher in our Sleep/Standby test with 0.27 watts for the PX2370 and the Asus MS238H drawing more than three times as much with 0.89 watts. With both monitor's center point calibrated to 200 candelas per square meter, the PX2370 drew 19.9 watts while the MS238H drew 22.4 watts. Based on our formula, the Asus MS238H would cost $8.55 per year to power, compared with the PX2370's $7.65 per year cost.

Service and support
Asus backs the MS238H with a two-year casing and panel warranty that covers the backlight, if purchased directly from it; however, some resellers will offer a three-year plan, with the same coverage. Asus also offers support through a 24-7 toll-free number, e-mail, and Web chat. The MS238H's documentation and support software are easily accessible on Asus' Web site.
