Our Verdict
Good for mixed usage. The picture quality is below average. However, this is made up for with excellent motion handling and input lag due to the 144Hz refresh rate and support for FreeSync. Unfortunately, the image degrades rapidly when viewed at an angle and the sides lose accuracy when viewed from up close.
- 144Hz refresh rate feels very responsive
- Input lag is excellent
- Edges of the screen appear nonuniform due poor viewing angle
- Low native contrast ratio
Decent monitor for office use. The AOC Agon AG271QX gets bright to overcome reflections, which is great. It also has a light-matte finish which handles direct glare well. The 1440p resolution is also comfortable for working on 1 or 2 windows at a time. Unfortunately, the edges of the screen look non-uniform due to the poor viewing angles and the image quality is below average.
Great choice for gaming. The AOC AG271QX feels extremely responsive due to the high native refresh rate and low input lag. The monitor also supports FreeSync to adjust the refresh rate to the game, which is great and removes screen tearing. Unfortunately, it can't flicker the backlight to clear up motion further and the picture quality is sub-par.
Decent monitor for watching movies and TV shows. The monitor handles reflections well due to great screen brightness and light-matte finish. Color accuracy is also decent out of the box. Unfortunately, the image degrades rapidly when viewed at an angle and the contrast ratio is sub-par.
Decent for creating media such as editing photos or videos. The monitor handles surrounding light well due to the light matte finish and can get bright to overcome glare. Unfortunately, it doesn't support the wider Adobe RGB color space and the image loses accuracy when viewed at an angle. The picture quality of the TN panel is also worse than average.
Doesn't support HDR. Also, the AOC AG271QX doesn't support HDR features such as a wide color gamut, and can't get bright. For an HDR gaming monitor, see the Samsung CHG70.

Popular Monitor Comparisons
While the AOC Agon AG271QX is a good monitor for mixed usage, it is focused on fast-paced gaming with high refresh rate, FreeSync support, and low input lag. For other uses, there may be better or cheaper monitors available. See our recommendations for the best gaming monitors for PC, the best 1440p monitors and the best gaming monitors for Xbox One X.
These are two different types of monitors, each with their advantages and disadvantages. The Acer Predator XB271HU Bmiprz is a G-SYNC compatible monitor that has wider viewing angles, so the image remains accurate when viewed from the side. The Acer also has better ergonomics, so you can position it to your liking with ease. If however, you have a dark room and sit straight in front, the FreeSync compatible AOC AGON AG271QX has more uniform blacks and a faster response time that leaves only a small blur trail behind fast-moving content.
The AOC AGON AG271QX is much better than the MSI Optix G27C. The AOC AGON has much better ergonomics, making it easier to place it in the most comfortable position. The AGON displays gradients with almost no banding and has a very fast response time, so motion looks crisp with very little blur trail. The higher resolution of the AGON makes it easier to get more done or to see more fine details in games.
The Samsung CHG70 is better than the AOC AGON AG271QX. The Samsung has better native contrast than the AG271QX, important for dark room viewing, although the AG271QX has better black uniformity. The AG271QX has a slightly faster response time, but the CHG70 has an optional black frame insertion feature that can improve motion by reducing persistence blur. Finally, the CHG70 supports HDR and can display a wide color gamut.
The AOC AGON AG271QX is better than the Dell U2717D for most users, unless you need a wider viewing angle. The AGON AG271QX has much better motion handling, with almost no motion blur and a fast refresh rate, with very little input lag. The IPS panel in the U2717D has a wider horizontal and vertical viewing angle, good for wall mounting or sharing your work with someone, but it has worse dark room performance.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
