The AOC P2779VC ($249.99) is a relatively affordable 27-inch monitor that lets you wirelessly charge your Qi-compatible phone or tablet by placing it on a tray located on the base of the monitor stand. It uses Plane to Line Switching (PLS) panel technology (similar to In-Plane Switching or IPS panel technology) to deliver very dark blacks and wide viewing angles, but it's missing a few basic features, including USB ports and an ergonomic stand, If you need wireless charging, it's worth a look, but you'll get better color and grayscale performance from the Philips Brilliance Full HD Curved LCD Monitor (279X6QJSW).

Design and Features

With its black-and-gold color scheme, the P2779VC stands out in a field crowded with matte-black monitors. The 27-inch PLS panel has a non-reflective coating and is framed by very thin (quarter-inch) black bezels on the top and sides, while the bottom bezel is a bit wider, at a half-inch. The stand offers tilt adjustability, but lacks swivel, height, and pivot adjustments.

The P2779VC's cabinet is half matte-black and half glossy-black, and the stand has a gold, rectangular base that has a built-in charging pad that, like the Dell S2317HWi, will wirelessly charge Qi-compatible devices, such as the Samsung Galaxy S6 Edge. There's a + sign in the middle of the base that marks the charging pad, and a tiny LED on the front edge of the base that glows amber while a device is being charged and white when the device is fully charged.

The panel has a maximum resolution of 1,920 by 1,080, which is decidedly low for a 27-inch monitor. It has a peak brightness of 300 cd/m2, a 1,000:1 contrast ratio, a 5-millisecond (gray-to-gray) pixel response, a 60Hz refresh rate, and a 16:9 aspect ratio. I/O ports are scarce; around back, facing outward, are two HDMI inputs, a VGA input, a headphone jack, and a power jack. You don't get any USB ports with this monitor, nor do you get a DisplayPort input.


Under the front bezel are four function buttons that are used to navigate the settings menus, and a power button. In addition to Brightness and Contrast settings, there are three Gamma settings and six picture presets, including Standard, Text, Internet, Game, Movie, and Sports. Other settings are made up of Dynamic Contrast Ratio (DCR), Clock, Phase, Sharpness, and five Color Temperature options (Warm, Cool, Normal, sRGB, and User). There's also a setting to enable or disable Qi charging capabilities, as well as settings for AOC's Dynamic ColorBoost option, which will enhance all colors or just certain colors, such as skin tones, greens, or blues. I'd recommend leaving this feature disabled unless you enjoy oversaturated colors.

AOC covers the P2779VC with a three-year warranty on parts, labor, and backlight. Included in the box are HDMI and VGA cables and a Quick Start guide.

The P2779VC turned in mixed results in our testing. The PLS panel produced very dark blacks, but had trouble displaying the darkest shades of gray in the DisplayMate 64-Step Grayscale test. Instead of gradually transitioning to black, the three darkest shades of gray appeared pitch black, which accounts for the muddy shadow detail in my test images. Light-grayscale performance was good, however, and viewing angles were wide, with no noticeable loss of luminance or color shifting.

Color accuracy was less than ideal out of the box. On the chromaticity chart below, color measurements are represented by the colored dots, and the ideal CIE color coordinates are represented by the boxes. As shown, only blue is close to being correctly aligned with its CIE coordinates, while red is just outside of its zone, and green is completely misaligned. I didn't observe oversaturated colors in my test patterns or while watching Marvel's Antman on Blu-ray, but there were traces of green tinting in my grayscale tests.


While not designed for gaming, the panel's 5-millisecond pixel response did an adequate job of handling fast-action sequences, but there were still occasional instances of motion blur in my Crysis 3 (PC) and Call of Duty: Infinite Warfare (Sony PlayStation 4) tests. Minor screen tearing was also present. The panel's 10.3-millisecond input lag, as measured by a Leo Bodnar Video Signal Lag Tester, was short, but not quite as short as our leader, the BenQ SW2700PT (9.5 milliseconds).

The P2779VC consumed 27 watts of power while operating in Standard mode (it does not offer a power-saving mode). The Philips 279X6QJSW consumed 24 watts in Standard mode and has an Economy mode that reduced usage to 15 watts. The Dell UltraSharp 27 InfinityEdge Monitor U2717D also used 27 watts of power, and like the P2779VC, it lacks a power-saving mode.


The AOC P2779VC is unique in that it features a built-in wireless charger for devices that are equipped with Qi charging technology. Its black-and-gold finish also sets it apart from other displays. That said, it's not the best performer out there. It had trouble displaying the darkest shades of gray in our tests, and its color accuracy is questionable. Moreover, it lacks features like USB connectivity, an ergonomic stand, and a DisplayPort video input. If wireless charging is not a priority, our Editors' Choice for affordable big-screen monitors, the Philips Brilliance Full HD Curved LCD Monitor (279X6QJSW), is a much better choice. It, too, lacks USB ports and an adjustable stand, but it delivers very accurate colors and solid grayscale performance, and it has a curved screen, with support for AMD's FreeSync anti-tearing technology, for just $50 more.
