Pros
Pro Cinema-like picture quality for an affordable price
The fact that a monitor of this price range has a 5M:1 contrast ratio is simply astonishing. This means users get cinema-like picture quality right at their desk.
Pro Good sound quality with no need for external speakers
This monitor's speakers are as good as those found on small TVs. They're located in the back and come with an audio jack for headphone connectivity.
Pro Immersive
The 2560x1080 resolution creates an immersive setup. This applies even for work tasks: multiple documents can be displayed side-by-side with no legibility sacrifice. It's equivalent to having two monitors with 1280x1080 screens.
Pro Advantageous for all uses
This monitor's ultrawide screen has advantages for all uses. When it comes to movie watching or gaming, the screen size contributes to a truly engaging experience. As far as general productivity goes, the ultrawide screen makes it easy to have different applications or documents open side by side.
Pro Great for watching movies
The 21:9 aspect ratio comes in handy when watching movies. This is the default aspect ratio at which almost all of the films are shot. Hence, you can watch your movies without having two black bars at the top and bottom of the screen.
Pro Has a headset hanger
One neat feature of the AOC AG271QX is a headset hanger which is situated near the monitor’s audio output.
Pro Has a metal stand
Unlike many other gaming monitors that are built purely from plastics, the AOC AG271QX does have some eye-catching and rigid metal parts. For example, the entire stand of the monitor is made from aluminum, which is an infrequent feature at the given price point.
Pro Well-handled motion
This monitor doesn't have any problems with ghosting or motion blur since they're kept under control by the aid of the panel's fast pixel response time and high native refresh rate.
As the monitor's pixels can change their colors fast enough to eliminate even the tiniest trails from fast-moving objects, the AOC AG271QX doesn't suffer from motion blur and ghosting. Such rapid color transition is possible because of the monitor's full pixel response time of 1 ms.
Additionally, the overall motion looks smooth and fluid because of the display's 144 Hz refresh rate, which ensure that the image updates every seven milliseconds.
Pro Decent responsiveness
The AOC AG271QX offers responsive and lag-free gaming experience as its input lag of 5.2 ms is on par with the majority of competitors in its price range.
Input lag corresponds to the delay needed by a monitor to process a single frame generated by a computer's graphics card. It can have a substantial impact on the overall gaming experience.
Pro Adjustable stand
Adjustability-wise, the AOC AG271QX has everything sorted as the monitor offers tilt, swivel, height, and even pivot adjustments which you can use to get the best viewing angles out of this panel.
Pro Features FreeSync
FreeSync eliminates stutter and vertical tearing as it allows the monitor to adjust its refresh rate to match the framerate of your graphics card.
The AOC AG271QX supports FreeSync in the 48-144 Hz range.
FreeSync works only with AMD's Radeon graphics cards.
Pro Fair picture quality
Featuring decent contrast ratio, high peak brightness, exceptional color accuracy, and excellent gamma response, the AOC AG271QX offers better picture quality than the majority of other gaming monitors in this price range.
While the monitor's dark scenes are not the top-notch, it does an outstanding job of reproducing images with vivid and consistent colors as well as some beautiful intermediate tones. Dark scenes look good thanks to the monitor's contrast ratio of 1040:1. Colors pop and appear luminous because of the monitor's peak brightness of 350 nits. Color inaccuracies are virtually unnoticeable to the human eye thanks to the average color error dE of 1.31. Mid-tones look lifelike because of the monitor's near-perfect gamma of 2.18.
Additionally, this QHD monitor displays sharper and more saturated scenes compared to its 27-inch FHD competitors, because it has 42% higher pixel density.
Pro Good for gaming
The AOC AGON AG271QX is an excellent choice for gamers at this price point because it offers high responsiveness and fantastic motion handling capabilities while keeping its picture quality to very high standards.
Pro Can fight glare
The AOC AG271QX does an excellent job in bright rooms, where the monitor's peak brightness of 350 nits allows it can deal with glare and heavy reflections.
Cons
Con Limited connectivity
This monitor has two HMDI ports, which is pretty good. However, it misses other display inputs such as DVI or Display Port, making incompatible with older computers.
Con Lack of support for ultra-widescreen in (old) games
A handful of games do not support 21:9 aspect ratio by default. Some examples are Overwatch, Fallout 3, and Starcraft 2. If this is important for you, it is recommended you test this issue before getting this monitor. But there are solutions: you can either install fixes (only available for some games) or play in windowed mode, using a different aspect ratio.
Con Slow response time
A response time of 5 ms on a gaming monitor is pretty awful. Considering its refresh rate, it is understandable but not acceptable. Note that this response time is from gray-to-gray.
Con 720p and 1080p videos are sandwhiched
This monitor's aspect ratio means that many online videos, such as those from Netflix or YouTube, will have black spaces on the sides, which can be annoying.
Con Unintuitive OSD menu
The monitor's on-screen display menu is messy and unintuitive.
Con Bad for cable management
The AOC AG271QX does not have any cable-management related features that are usually offered even by some lower-grade monitors.
Con Needs a brief calibration
To get the most from the monitor's picture quality, you'll need to do a short calibration procedure. The procedure is well-documented, and all the key parameters and ICC profiles are available on the Internet.
Con Requires high-end hardware
This QHD monitor will put more strain on your graphics card compared to a regular FHD monitor simply because it has 42% more pixels to run.
Some user tests revealed that running a game at the QHD resolution causes 30-40% FPS drop, compared to the FHD resolution.
Con Has an external PSU
Finding the right place for the monitor's power supply brick might cause you some inconvenience, especially if you are going to mount the monitor on a wall.
