Acer GD235HZ review:

Acer GD235HZ

Nvidia 3D Vision performance: We tested 3D performance using Call of Duty: Black Ops. The GD235HZ uses Nvidia's 3D Vision technology, and Black Ops looked great running on the display in 3D, with the monitor's already high vibrancy contributing to the visual panache.

We also got a chance to see how the GD235HZ handled 3D photos and watched a short 3D movie. 3D photos are, from technical standpoint, interesting, but we don't think that the effect adds much to still images. The photo seems to move and slightly shift perspective as you move your head, but it doesn't really enhance pictures in any meaningful way. Also, it makes foreground objects look like 2D cutouts, lacking any depth.

The 3D movie of a Nurburgring race fared better, looking like native 3D content and not something post converted to 3D. The film had multiple levels of depth, and the foreground assets didn't look like cardboard cutouts.

The 3D vision glasses use active shutter lenses, and as such, when viewing any 3D content, expect it to look darker than when viewing normally.

Photos: The Acer GD235HZ delivered sharp-looking photos, but when viewing dark-skinned faces, the skin had a slight, but noticeable green tint. This was especially true when compared side by side with the Samsung PX2370, which pushed red more than the average monitor.

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 colors as they were intended to be. 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. The GD235HZ uses a TN panel, and indeed gets very dark when viewed from below. We were fine viewing text from the left or right sides as long as our perspective didn't pass a 30-degree threshold. Beyond that, text became very difficult to read.

Power consumption
The Acer GD235HZ achieved fair power consumption, with a Default/On power draw of 37.5 watts, compared with the Samsung PX2370's 25.01 watts in the same test. In our Sleep/Standby test, the GD235HZ costs 2.8 watts and the PX2370 pulled a lower 0.27 watt. Based on our formula, the GD235HZ would cost $12.25 per year to run, compared with the PX2370's lower $7.65 per year.

Service and support
Acer backs the GD235HZ with a three-year limited parts and labor warranty that covers the backlight; this matches the great coverage from other monitors vendors like Samsung and Dell. E-mail support is provided via a form on Acer's Web site, and drivers for the display are available there as well.

As a gaming monitor or just a monitor to watch movies on, the Acer GD235HZ is a very good performer with a fast refresh rate, fairly deep blacks, and a level of vibrancy that matches some of the best monitors out there. While it skimps on ergonomic options and looks pretty typical design-wise, it does include the connection option trifecta and a capable OSD with plenty of usefulness.

Its cost, at $345, is slightly pricey for a 23-inch monitor, but if you're looking for a gaming monitor with 3D capability, it's actually a pretty great deal. For a non-3D, general use monitor with great performance, the Samsung PX2370 gets a higher recommendation.
