Although it's difficult to find a significant fault with Asus' 23-inch LED-based MS238H--thanks to its low $190 price--the monitor does give you amble opportunity to do so. As a result of its design, the display is constantly tilted 10 degrees back, making it sometimes difficult to see the screen correctly. Because of its constant tilt, the monitor topples with the slightest disturbance, and its adds a slight green push to its images. However, its overall performance is good and its footstand has a novel design that adds to the monitor's aesthetic appeal. If paying no more than $200 for a new monitor is a priority for you, we recommend that you buy the MS238H because of its overall satisfying performance. If you can afford another $100, we recommend that you buy either the Samsung XL2370 or the PX2370 because of their superior performance.
Design and features
At first glance, the Asus MS238H strikes us as a typically stylish monitor with a thin, black, glossy chassis and a minimalist OSD array. However, the display stands out thanks to a unique, wheel-like, circular band that is the monitor's stand. The 5-inch diameter band props up the monitor from the bottom of its back, leaving no space between the bottom of the panel and the desktop. Although the panel tilts an additional 10 degrees, because of the wheel stand, the panel remains tilted 10 degree at all times and is never at a perfect 90 degree angle. The stand keeps the monitor stabilized when knocked from the sides; however, when it encounters a force from the front--like a light breeze--it topples over. OK, a light breeze probably isn't strong enough, but a light knock with your fist definitely is. The bezel is 1.2 inches wide on the sides and the panel is a short 0.6 inch deep at its most shallow and about 1.5 inches at its deepest depth. The monitor does not have height, pivot, or swivel adjustment options.
The monitor includes VGA and HDMI connections. Thankfully, Asus includes an HDMI to DVI cable. The monitor's connections are located on the back, lower-right corner and are clearly labeled and easily accessible. To the right of the VGA input is a headphone jack labeled "For HDMI."
Like the Samsung P2450h, the MS238H forgoes buttons, in favor of "touch areas." Asus denotes each area with a small white circle and each has a different function. The actual button labels, which glow white, appear above the dots once the area is touched. We were able to calibrate the monitor in a dark room easily since the buttons don't require pinpoint accuracy to function and the illumination of the button labels are enough of a guide.
The onscreen display button array consists of a Menu button, an Up and Down button, a Source button, and a preset cycle button. The monitor's Up and Down buttons also doubles as the Brightness and Contrast shortcuts. Navigating the OSD is simple, although it took us a few minutes to get accustom to using Menu as the "Enter" button. The MS238H's preset modes include Standard, Theater, Game, Night View, and Scenery. Each preset changes the color temperature and brightness of the display with the intent of them being appropriate to the task at hand. Its additional color preset options include Cool, Normal, Warm, SRGB, and User Mode; the latter letting you change the RGB values individually. Finally, the "Skin Tone" option includes a Reddish, Bluish, and Normal setting.

We tested the Asus MS238H through its HDMI connection connected to a Windows Vista PC via the included HDMI to DVI cable. The display posted a composite score of 87 on CNET Labs' DisplayMate-based performance tests; a few points below the Samsung PX2370's 97. In our screen Uniformity Test, we noticed dark patches on the screen, indicating that light from the backlight was far from uniform. Not surprisingly, in our Dark Screen test, the display's backlight bleeding can be seen on the top and bottom edges of the screen. In our Black Level test, the MS238H crushed very dark grays to the point that a level six gray--which is six levels above true black--was the darkest color the monitor could display other than true black; indicating a high black level. With Color Tracking, we noticed a slight greenish hue; however, the hue was only obvious when the monitor was next to the Samsung PX2370.
Text: Viewing text on the display we didn't find any color problems with black text on a white background and fonts were clearly visible down to a 6.8 point size.
Movies: We tested the Asus MS238H using the Blu-ray version of "Avatar;" however, using its Cinema mode preset, we found that dark detail was lost in dark scenes. With its Standard preset, its dark detail improved, but it was still not as good as the PX2370 was. The MS238H's color quality is good, if slightly green.
