The AOC e2352Phz monitor has a polarised panel that works in conjunction with the bundled TriDef Windows-only software to enable 3D graphics from a PC. There's support for 3D photos, video and gaming although 3D Blu-ray is not supported.
Unlike nVidia's rival 3D Vision system, TriDef uses cheaper passive Polaroid glasses rather than expensive shutter-based ones requiring rechargeable batteries. A pair of glasses is included in the AOC e2352Phz box along with a set of clip-on lenses for spectacle wearers.
Using a polarised display has the disadvantage of effectively halving the screen's resolution while in 3D mode. This is because half of the screen's available pixels must be sent to each eye simultaneously. In the AOC e2352Phz's particular set-up, left-eye and right-eye images are interleaved as alternate rows of pixels.

Nvidia's solution maintains the full screen resolution by doubling the rate at which frames are displayed and then sending one full-resolution frame to each eye in turn.
TriDef's Ignition application automatically scans your PC for games which it then matches against a 500-strong list of pre-built profiles designed to achieve the best possible 3D experience. You can then launch your games directly from this application and it will take care of the set-up for you – at least in theory.
When the 3D mode works it's reasonably convincing, although the effect is sensitive to your viewing angle and seating position. However, it's simply not as silky-smooth as we would like and there are still a few glitches to be ironed out. The Tridef software is updated regularly, and many of our problems were sorted out by installing the upgrade. For now though, nVidia's 3D Vision solution seems to offer a better 3D experience.
YouTube also provides 3D content, and the AOC e2352Phz is a great way to view it. You also get specific support for Google Earth, which is really rather impressive in its full three-dimensional glory.
The software comes with its own photo and media player applications which automatically switch into 3D mode to display the required content.

Most of the time you're going to be using the e2352PHz in 2D mode, and in this configuration the monitor behaves much like any other monitor based on a low-end TN panel. Viewing angles are somewhat restrictive and colours far from accurate – but neither of these issues should cause undue concern if your primary use is for 3D effects.
An LED backlight helps keep the display slim, but AOC has still found room to fit the power supply internally. HDMI, DVI and VGA inputs are provided, along with an audio input and a headphone socket. All of these ports are of the “direct insert” type, mounted facing out fromo the panel for easy connection.
At around £191, the AOC e2352Phz costs a good deal more than a standard 2D display. Unfortunately AOC hasn't really gone out if its way to help 3D fans. There's scant information provided how the 3D mode operates or what should be expected from it. You're left to install the software and experiment for yourself.
Despite what is a very large, clear and rather pretty on-screen menu, the display's control buttons can be rather frustrating. The button legends are difficult to read unless brightly illuminated and operating them by feel often results in pressing the wrong button – we often turned the display off altogether.

AOC e2352Phz: Lab Results
AOC specifies the monitor with 250cd/m2 maximum brightness. Our tests showed a figure reasonably close to that of 222cd/m2. Using a checkerboard test for contrast ratio, we measured a real-life figure of 651:1, a good result. Average uncalibrated colour error was 7.8 delta E.
With reference to the NTSC range, we found the AOC could reproduce 78% of that standard's colour gamut, and 110% of the sRGB colour gamut.
Power consumption at maximum brightness was 33W, falling to just 24W at a measured 120cd/m2 brightness setting.
- Maximum measured brightness: 222 cd/m2
- Black point luminance: 0.35 cd/m2
- Maximum checkerboard contrast: 651:1
- Average uncalibrated colour error: 7.8 delta E
- Percentage of NTSC gamut: 78%
- Percentage of sRGB gamut: 110%
- Power consumption at maximum brightness: 33W
- Power consumption at 120 cd/m2: 24W
