AOC AG271QG; An In-Depth Review

Though initial high refresh rate monitor models were restricted to Twisted Nematic (TN) panel technology, we are seeing a few newer models with high refresh rate as they use alternative panel types. The most common of course, is the 27-inch 144Hz AHVA (Advanced Hyper-Viewing Angle) panel that sports 2560x1440 resolution. This panel is a actually a type of IPS (In-Plane Switching) panel technology which is designed for superior colour accuracy and viewing angle performance than the TN. And the AOC made sure they have their hands on this technology with their new AOC AGON AG271QGa monitor that offers a good combo of responsiveness and image quality, which would definitely entice gamers. So what’s in this new monitor? And what makes it better than its gaming competitors? Check out this in-depth review from Dual Monitors Guide to know more.

Who is it for?

AOC AG271QG is obviously designed for gamers; it packs the responsiveness of a good gaming monitor, with the image quality you can expect from high-end monitors designed for colour-demanding tasks. It also comes with G-SYNC technology and runs at 165Hz refresh rate, which definitely makes it a great choice for avid gamers.



Earlier last year, AOC introduced their AGON gaming monitors line, which is a series of gaming monitors that represents the brand’s PC gaming segment aimed for competitive gaming. One of their early models is the AOC AG271QG, a 27-inch monitor that features tons of gaming-centric features, from Nvidia G-Sync anti-teach technology and fast 165Hz refresh rate. But the most impressive about all is it uses an IPS panel, allowing the screen to deliver sharp image detail, excellent grayscale performance, and of course, the wide viewing angle. All these things work hand in hand for gaming.


Fast Refresh Rate, Enabled Nvidia G-Sync, Excellent for Gaming

AOC AG271QG is definitely a gaming beast, and it has no issues running big title and highly demanding games such as Crysis 3 on PC and Call of Duty: Infinite Warfare on Sony PlayStation 4. Gaming shows no blurring, ghosting or stuttering

For Input Lag (the time it takes for the monitor to react to the command of the controller) was never an issue, as it scored a decent score of 12.3 milliseconds from the Leo Bodnar video signal tester. Its competitor BenQ XL2430T scored a better score with 9.5 milliseconds input lag. Screen tearing is very minimal, though you can actually get rid of it as soon as you activate the Nvidia G-Sync feature. It definitely eliminated a lot of issues, while the action feels noticeably clear.


Rich, Evenly Saturated Colors and Superb Grayscale Performance, All for Gaming

Colors were good in this monitor; they were evenly saturated while playing games or watching movies on Blu-ray. Image details were also sharp through test images. However, the out-of-the-box colour accuracy of this product is a little skewed. based on the chromaticity test, the color blue stayed close to its ideal zone, while green is completely outside, which causes tinting. This issue however, is extremely common for a monitor of its type, and the flaw really usually gets unnoticed.

For the grayscale performance, the monitor has no trouble displaying each shade of gray based on DisplayMate 64-step grayscale test. This means there is a consistent quality throughout this display, as it provides excellent shadow details and highlights.



AHVA Screen for Higher Resolution and Overall Better Picture Quality

As said earlier, this monitor uses AHVA (advanced hyper-viewing angle) panel for its screen. It’s a type of IPS panel capable of running higher refresh rates (165Hz) and runs at 2560 x 1440 resolution. It has a peak brightness of 350 cd/m2 and a contrast ratio of 1000:1 at 16:9 Aspect Ratio.


Fast Pixel Response Time for Smooth Gaming Experience

AOC AG271QG runs games at 4ms (gray-to-gray) pixel response time. It may be a little short than 1ms response time we usually see from top-tier gaming display, but it is definitely good enough to run games smoothly. Definitely impressive, considering it’s actually using an IPS panel. As a matter of fact, many good quality gaming monitors out there run at 5ms.


Excellent Viewing Angle

As what we can expect from an IPS panel monitor, the viewing angle of AOC AG271QG is superb; there were no luminance loss or shifting of colors when viewing the monitor from side angles, bottom or top. Truly, it remained true to its promise of IPS panel.


With Built-In 2W Speakers for General Use

AOC is kind enough to include a pair of built-in 2W speakers in this monitor, which is quite a plus, as many gamers would not want to have tons of stuff on their desk, and extra external speakers can definitely take up some space. The speakers however, are fairly low quality, lacking bass, which is understandable, since they’re only 2W, and we all know built-in speakers don’t usually come with good quality.


With VESA Mounting Option

As with many gaming monitors right now, this one comes with 100x100mm VESA mounting option, which is accessible through a special plate, which also holds the stand of the monitor.


Design and Features

Like many AOC monitors, the AOC AG271QG come in a sleek profile and to distinguish as a gaming monitor, it features red, black and silver color combination. The red is actually a dark red splash which is located at the backside of the monitor. It comes with matte-effect that looks like wings (V shaped) and runs through the central region of the monitor.


Buttons and Controls

As with many monitors, the control buttons for this monitor are placed on right bottom part of the bezel with OSD (on-screen display) labels. The ‘pressable’ buttons are facing downwards, and they’re not touch-sensitive.

As expected, this monitor lacks the picture and gaming presets we usually expect from gaming monitors. What it has are the basics, such as Luminance settings which provides controls for the Contrast, Brightness, Game Color (which punches the intensity levels), Shadow Control (improves black levels), Gamma and Overdrive (speeds up the monitor’s pixel response). For its Color Setup, the menu includes settings for Blue Light setting, which as we know, helps in easing eyestrain, as well as 5 settings for Color Temperature, namely Warm, Normal, Cool, sRGB and User and individual settings for colors Red, Green and Blue intensity levels. It doesn’t have the 6-axis color settings that we found from Acer Predator Z1 (Z271), ViewSonic XG2703-GS and LG 27UD88-W.

The right side of the cabinet houses the headphone hook, which folds when not in use. Also included is a headphone jack and audio input, as well as a couple of USB 3.0 ports. One port is dedicated for fast-charging of your mobile devices. Unfortunately, there aren’t many options when it comes to this monitor’s video ports. It has one DisplayPort and an HDMI input at the backside of the monitor, as well as an upstream USB 3.0 port and a couple of downstream USB 3.0 ports. But that’s pretty much it for connectivity.


Fully Adjustable Stand for Comfort and Ergonomics

Unlike most monitors of its size, AOC AG271QG  actually comes with a good quality monitor stand. It’s made up of heavy metal, which ensures stability and safety for the monitor, and it offers wide range of adjustments, from height adjustment,  tilt, swivel and pivot options (switching the monitor’s orientation from landscape to portrait and vice versa). It also comes with a height gauge that lets you set the monitor to the perfect height every time.


Tech Specs

Package includes the DisplayPort, HDMI and USB cables.


Bottom Line

Gamers will definitely appreciate the beauty of AOC AG271QG. This gaming monitor has many of the qualities gamers will need, if not all. It looks good, and quite fast, as it can run up to 165Hz refresh rate, not to mention its ability to eliminate screen tearing.

Unfortunately, there aren’t lots of options for video inputs, and it lacks the gaming presets that we often find from good quality gaming monitors, such as Acer Z271 and ViewSonic XG2703-GS. However, it has no trouble delivering excellent gaming performance, as well as grayscale and picture quality. It also comes with four USB ports and a fully adjustable stand, which is something we don’t usually find in many gaming displays.

If you’re looking for something better than this display, then you may consider the ViewSonic XG2700-4K. It’s way cheaper, and can deliver accurate colors with stunning Ultra HD picture. Also, it comes equipped with FreeSync technology from AMD, 5 video inputs, as well as optimized gamer presets and advanced color settings.

All in all, the AOC AG271QG certainly delivers all of its promises, from speedy refresh rate, smooth gaming, and a fully adjustable stand for comfort and ergonomics. However, it doesn’t really give you the best bung for your buck, as it can be expensive.
