AOC Q2770PQU full review
The Q2770PQU is a new addition to AOC’s line of professional monitors, a 27-inch panel with an iMac-like 2560 x 1440-pixel resolution. It takes a Super PLS panel, Samsung’s IPS-style technology, to promise crisp and vivid images.
A substantial stand swivels on its circular base, allowing tilt back and forth, and also allows the panel to rotate into a vertical portrait orientation. The monitor itself looks a little square, with a thick, brushed-metal effect plastic frame, and asymmetrically thicker bezel running along the bottom.

Legends for the four menu buttons are raised plastic, making them nearly impossible to read. The buttons hidden under the edge are large and well-spaced, while the on-screen menu system is reasonably logical, a semi-transparent overlay that seemingly rises from the screen bottom.
Overall build quality was satisfactory if a little plasticky, with no discernible light leak from the edges. Thanks to the white LED backlight it doesn’t consume much power either. At 50% brightness, it drew around 24W, rising to 36W at full brightness.
It has one each of analogue VGA input, DVI-D, DisplayPort and HDMI. Additionally there are two USB 2.0 and two USB 3.0 ports, to add a powered hub to your desktop.
The two USB 2.0 are hard to reach, facing down with the rest of the inputs but useful for a wired keyboard and mouse. The USB 3.0 ports are on the right side, one confusingly coloured yellow rather than blue. This may be designed for charging although it was unable to power our iPad.
For basic sound effects there’s a single speaker that’s audible through the rear ventilation holes. Needless to say and in common with most PC monitors it didn’t sound good.
While the AOC doesn’t deliver any thrills in its style it makes up the slack in the pure quality of the display image.
Its measured sRGB gamut was right on the money with 100% coverage. For the wider AdobeRGB gamut it still recorded a respectable 80%. Setup for a Gamma of 2.2 it was found to be very accurate, following the curve through the brightness up to 100% with essentially no variation.
Brightness level was more than you’d need in even a bright office, at 300 cd/m2. Contrast ratio in a chequerboard test, from 50% to full brightness, was a consistent 580:1. An overall average Delta E figure of just 0.90 was a great result.
Colour uniformity across the screen was reasonably good, with only the top right corner exceeding a Delta E figure of 3.0 at 100% brightness, while at a more usable 50% brightness this dropped to a Delta E of 3.2.
Luminance uniformity was below professional colour grading levels but quite usable. At full brightness the left and right middle parts of the screen were 14% and 15% darker. At 50% brightness they were around the same, at 16% darker on the left and 14% darker on the right. But these are not terrible results and will barely be visible by eye.
Judged subjectively, the panel’s image quality was exceptional. In the OS X interface, fonts were rendered very cleanly with no visible artefacts. Just avoid the Clear Vision option – confusingly found by pressing the panel ‘–’ button – which tries to oversharpen and ruin the image. Black levels seemed inkier than is normally found with matt anti-glare finishes, and there no colour banding was evident whatsoever.
