AOC U3277PQU 32-inch 4K display review

he AOC U3277PQU is a high-end 4K display, with a large 32-inch screen and a specification suited to graphic design work and gaming alike. It has a 10-bit IPS AHVA panel, built-in speakers, a picture-in-picture mode and a fully flexible stand – for a relatively reasonable price.
The different pricing tiers among 4K displays are quite clearly split between different panel technologies and screen size. For what might be considered an “entry-level” 4K screen, you pay around £350-450, and for that you get a TN (twisted nematic) display with screen size of around 27 inches, with a low refresh rate, usually 1ms grey-to-grey.

An IPS panel for better viewing angles and overall picture quality adds to the cost considerably, as do screens larger than 27 inches. We’ve seen a number of 4K IPS displays with 32-inch screen sizes, such as the BenQ BL3201PT (Review HERE) and even 40 inches, in the case of the Philips Brilliance BDM4065UC (Review HERE).

At the very top end of the scale, you pay considerably more for features such as Nvidia G-Sync, as with the Asus ROG Swift PG27AQ (Review HERE) or if you want absolutely superb colour accuracy, you need to dig really deep into your pocket.
The 32-inch Asus ProArt PA329Q sports a lovely 100 per cent Adobe RGB coverage while Dell’s UltraSharp UP3216Q and EIZO’s beautiful ColorEdge CG318-4K displays offer good DCI-P3 coverage as well, but all three of these examples carry four-figure price tags.
AOC’s U3277PQU fits in between these ends of the pricing spectrum. It costs around £600, and is a 32-inch 4K display with an IPS panel and therefore, associated 178 degree viewing angles.
It sits alongside another similarly named AOC display, the £350 Q3277PQU, which carries a near-identical design but with a 2,560×1,440 native resolution. The ‘Q’ clearly stands for Quad HD, while the ‘U’ in the U3277PQU stands for Ultra HD.
AOC lists a 4ms response time, 350cd/m2 brightness, built-in speakers and audio passthrough, four display inputs and a stand with full tilt, pivot and rotate support.
Generally 4K monitors are still significantly more expensive than displays with a lower native resolution, but the AOC U3277PQU offers a lot of monitor for the money, and will work well for gaming, graphic design and general desktop use.

AOC U32 Box
The listed features on the AOC U3277PQU packaging show off its 4K resolution, flicker-free panel, 10-bit colour, MHL support, audio and PIP mode.
AOC U32 Accessories
AOC has been particularly generous with the cabling included with the AOC U3277PQU. You get HDMI, DisplayPort and VGA video cables, power and a USB 3 uplink cable, along with an audio pass-through cable. Plus the usual CD with the manual and some bundled software, and a colour uniformity sheet.
AOC U32 bag of screws
There’s also a bag of screws included for manually attaching the stand.
AOC U32 frontAOC U32 rear
You can’t see it in these photos, but the 32-inch screen on the AOC U3277PQU is certain to dominate any desk as it is the size of a small TV.
AOC U32 rear power
The power supply is internal so the AOC U3277PQU is used with a standard kettle lead. There’s also a hard power switch.
AOC U32 base 1
To support a large 32-inch panel, AOC supplies a suitably large base for weight distribution.
AOC U32 base 2
With the usual key locking system on the underside.
AOC U32 stand 1AOC U32 stand 2
The stand is likewise extremely sturdy.
AOC 32 Cable Management
On the back of the stand is a cable management clip. It’s not as versatile as the holes in the middle of some monitor stands, but at least it’s there.
AOC U32 VESA
It connects to the back of the panel using the bundled set of screws, which needs to be performed with the panel laid face down.
AOC U32 inputs
The included set of inputs is a tad puzzling. There’s only one DisplayPort 1.2 input, and one HDMI 2.0 port, both capable of full 60Hz 4K output.

 DVI is not capable of 60Hz though, and VGA cannot even manage 4K. It would been far more useful to ditch these legacy connectors and instead include extra HDMI or DisplayPort inputs.
AOC U32 USB
There’s a four-port USB hub built into the side.
AOC U32 lock
And also Kensington lock support.
AOC U32 logos
On the bottom left is a set of logos listing the features of AOC U3277PQU.
AOC U32 buttons
And on the bottom right are the usual buttons to control the OSD, with labels on the front of the bezel and a set of five physical buttons underneath it.
AOC U32 OSD Input
A quick press of the left-most button provides a shortcut to switch the display input. Another inwards press cycles through the list.
The next button enables Clear Vision, or moves back through menus.
Following that is a shortcut for volume control. The last (fifth) button is the ‘soft’ power button. While the fourth one along displays a menu with all the monitor’s settings.
AOC U32 OSD Luminance
The Luminance menu contains the contrast and brightness settings, Overdrive, an ECO mode, DCR (dynamic contarast, left off for testing) and 3 gamma settings.
AOC U32 OSD Color
There are four colour temperature settings – Normal, Warm, Cool and sRGB, and a user-customisable setting, with Red, Green and Blue sliders.
DCB (dynamic colour boost) slightly over saturates certain colours, depending on the on-screen content. It’s especially noticeable with bright shades of red and green.
AOC U32 OSD PIP
The PIP Setting menu is for enabling and adjusting the picture-in-picture or picture-by picture setting.
You can switch the main display and the PIP source, adjust its size and on-screen location, and enable audio from the secondary source.
AOC U32 PIP
And here it is in use, with a PS4 connected to the HDMI 2.0 input
AOC U32 OSD Picture
The PictureBoost menu provides options to adjust the brightness and contrast of a specific part of the screen. You can customise its size and location.
AOC U32 OSD Extra
The Extra menu lets you choose the selected input, adjust the image ratio, enable DDC/CI and reset the monitor settings.
AOC U32 OSD Setup
As well as adjusting the timeout (invaluable when looking for certain settings) the OSD Setup menu lets you move the OSD around, enable the Break Reminder option that reminds you to take exercise every 30 minutes, and change the OSD language.
Finally, we get to the picture testing results. As always, we used a DataColor Spyder4 Elite Colorimeter, with measurements taken of the AOC U3277PQU in its out-of-the-box, uncalibrated state, then again after calibration.
The screen is reset to factory settings before the test and calibration is done with brightness set to 120 cdm/m2, which is a setting of 40% in the OSD. By default, brightness is set to 90%.
Without running the risk of repeating ourselves, 2015 has seen a dramatic increase in the panel quality of even affordable displays. For a mid-range display, particularly one offering 10-bit colour, close to 100% sRGB coverage is now expected, with 70-80% Adobe RGB.

 For even greater colour accuracy, you’ll need to be looking at more expensive displays aimed specifically at graphic designers.
AOC U32 Gamut
Firstly, the uncalibrated results of the AOC U3277PQU show 100% sRGB and 79% Adobe RGB coverage.
uniformity
The panel shows some strong 15% brightness deviation on the right, but the left-hand side is quite close to the centre value.
AOC U32 Brightness
Despite the claimed 350 cd/m2 we only measured a maximum brightness of 290.3 cd/m2. The contrast ratio is a very good 620:1 and the black point is a standard 0.47.
AOC U32 Tone 1AOC U32 Tone 2AOC U32 Tone 3
The Gamma 1 setting shows a measured display gamma of 2.2, Gamma 2 drops this to 2.1, while Gamma 3 is 2.4
AOC U32 OSD
The OSD settings show the White Point shifts from 6000K to 6800K when the Normal setting is enabled, and leaps to 8300K when in the Cool mode.
AOC U32 Accuracy
Colour accuracy is yet another area of massive improvement in displays over the last year, with the AOC U3277PQU achieving a Delta E result under 1.
Then we measured the screen again after calibration.
AOC U32 Gamut calib
AdobeRGB coverage hits 80%.
AOC U32 Brightness calib
The white point drops to 5800K.

And Delta E colour accuracy remains roughly the same.
Overall, the subjective view of the AOCU3277PQU picture quality is good. The screen is sharp and bright, while the colorimeter results show excellent accuracy.
With calibration the results don’t seem to change hugely, although in our subjective view, the resulting picture was less yellow.

 Games testing showed no problems with ghosting, and the speaker output was clear, although not especially loud, and therefore not a replacement for a proper set of stereo speakers.
If you’re not after the very finest colour accuracy or advanced monitor gaming features such as 144Hz or adaptive-sync technology, the AOC U3277PQU is a great choice.
Its biggest selling point is its super high resolution 32-inch screen, which is great for gaming and gives a large desktop area to work on.
The stand tilts, rotates and pivots and the OSD is a little basic, without any remote control or joystick controller, but it’s quick to find settings and options through the menus.
Although our results showed a disappointing inability to hit the claimed 350 cd/m2 brightness level, subjectively, the picture quality is as bright as you could want from a general-purpose display.
back page
We’re not even sure why AOC bothered with a VGA input, besides backwards compatibility with (now ancient) portable devices. A second HDMI input would have been welcome. But it’s great to see the newer HDMI 2.0 standard included on a 4K display, as it should be, providing 60Hz 4K video over HDMI.
AOC could work on a better input system. Asus is light years ahead of the competition with its joystick controls, and Philips has something similar on some of its displays.
As of now, the price is spot-on for a 32-inch display. It roughly matches a very close competitor, BenQ’s 32-inch BL3201PT both in feature list and price.
Overall, we’d consider the two to be neck and neck. While any 32-inch display will carry a price tag that’s hardly pocket change, the £600 price here is justified by the superb list of features.
