The AOC Q27G3XMN is a 27-inch budget gaming monitor. It's rather unique for a low-cost monitor as it features Mini LED backlighting with 336 dimming zones, which is something mainly more expensive monitors have. It also has VESA DisplayHDR 1000 certification to ensure a high brightness and contrast ratio. Besides that, it's focused on gaming as it has a VA panel with a 1440p resolution and a 180Hz max refresh rate. It also has variable refresh rate (VRR) support. It comes with an ergonomic stand, one DisplayPort 1.4 input and two HDMI 2.0 ports, but other than that, it's barebones in extra features.

Our Verdict

8.1 Mixed Usage

The AOC Q27G3XMN is great for most uses. It's excellent as a gaming monitor thanks to its 180Hz refresh rate, VRR support, and fast response time, but there's a bit of smearing with fast-moving objects. It's also amazing for gaming in dark rooms or even watching content in the dark, as it displays deep blacks, has a good local dimming feature, and there's minimal blooming around bright objects. It's excellent even for HDR, thanks to its high peak brightness, so highlights stand out. Lastly, it's also good for office use or content creation, as it has good text clarity, good reflection handling, and fantastic ergonomics. Still, the image appears washed out from the sides because it has narrow viewing angles.

Pros
  • Bright enough to fight glare.
  • Good text clarity.
  • Fantastic ergonomics.
  • Fast response time at any refresh rate.
  • Good Mini LED local dimming.
Cons
  • Narrow viewing angles.
  • No extra office features.
  • Noticeable red tint with some picture settings.
7.6 Office

The AOC Q27G3XMN is good for the office. It has a 27-inch screen with a 1440p resolution, and it has good text clarity. It's also good to use in a well-lit workspace as it gets bright enough to fight glare and has good reflection handling. While its fantastic ergonomics make it easy to adjust, it has narrow viewing angles, so the image looks washed out from the sides. It also doesn't have many extra productivity features, like a USB hub, so you can't connect your devices directly to it.

Pros
  • Bright enough to fight glare.
  • Good text clarity.
  • Fantastic ergonomics.
Cons
  • Narrow viewing angles.
  • No extra office features.
8.7 Gaming

The AOC Q27G3XMN is excellent for gaming. It has a max refresh rate of 180Hz with an incredible response time, resulting in minimal motion blur, but there's still a bit of smearing with fast-moving objects. Luckily, it has a low input lag at any refresh rate for a responsive feel. It also supports FreeSync VRR and G-SYNC compatibility to reduce screen tearing, but it can't take full advantage of gaming consoles as it lacks HDMI 2.1 bandwidth. On top of its excellent gaming performance, it's even amazing for dark room gaming as it displays deep blacks thanks to its high native contrast ratio and good local dimming feature.

Pros
  • 180Hz refresh rate and VRR support.
  • Fast response time at any refresh rate.
  • Low input lag.
  • High contrast ratio.
Cons
  • Can't take full advantage of gaming consoles.
  • Some black smearing.
8.0 Media Consumption

The AOC Q27G3XMN is great for media consumption, whether you watch content in dark or bright rooms. It has a good Mini LED local dimming feature that helps it display deep blacks in dark rooms, and there isn't too much blooming around bright objects, either. Even in a bright room, it gets bright enough to fight glare and has good reflection handling. It also gets very bright in HDR, enough for highlights to pop. While it has fantastic ergonomics that make it easy to adjust, it's hard to share the screen with a friend next to you because it has narrow viewing angles, making the image appear washed out from the sides.

Pros
  • Bright enough to fight glare.
  • High contrast ratio.
  • Good Mini LED local dimming.
Cons
  • Narrow viewing angles.
7.9 Media Creation

The AOC Q27G3XMN is very good for content creation. It has fantastic accuracy before calibration in the sRGB mode, but some other picture modes have a warm color temperature, resulting in a red tint. Its 27-inch screen is big enough for multitasking, and it has fantastic ergonomics that make it easy to share the screen with someone else, but it has narrow viewing angles that make the image look washed out from the sides. On the plus side, it's great if you need to edit content in bright or dark rooms, as it gets bright and displays deep blacks with minimal blooming.

Pros
  • Bright enough to fight glare.
  • Good text clarity.
  • Fantastic ergonomics.
  • Fantastic accuracy in sRGB mode.
Cons
  • Narrow viewing angles.
  • No extra office features.
  • Noticeable red tint with some picture settings.
8.5 HDR

The AOC Q27G3XMN is excellent for HDR. It has a high native contrast ratio that's further improved by its good local dimming feature, and there's minimal blooming in dark scenes. It also gets very bright in HDR, enough for highlights to pop. Lastly, it displays a wide range of colors, but not all colors are accurate because of some tone mapping issues.

Pros
  • High contrast ratio.
  • Good Mini LED local dimming.
  • Gets very bright in HDR.
  • Displays wide range of colors.
Cons
  • Some tone mapping issues.

Differences Between Sizes And Variants

We tested the 27-inch AOC Q27G3XMN, which is the only size available for this monitor. The full model code may vary between regions and retailers, as it's also available as the Q27G3XMN/BK in Europe and the UK, but it performs the same.

Model Size Resolution Panel Type Native Refresh Rate Max Refresh Rate
Q27G3XMN 27" 1440p VA 165Hz 180Hz

Our unit was manufactured in July 2023; you can see the label here. It was tested with firmware version 1.4.

Compared To Other Monitors

The AOC Q27G3XMN is an excellent budget gaming with better picture quality than most other low-cost models thanks to its Mini LED backlighting, making it a great choice whether you game in a bright or dark room. While it doesn't have HDMI 2.1 bandwidth to take advantage of gaming consoles, it's still an excellent choice for PC gaming, thanks to its fast response time. It doesn't have as much smearing as on other monitors with VA panels, but it's still there. That said, this monitor's availability varies, so if you find it at a low price, it's best to get it while you can. Otherwise, you'll have to get a budget option with worse picture quality, like the Dell G2724D, or you'll have to spend more on another Mini LED monitor, like the Acer Nitro XV275K P3biipruzx.

See our recommendations for the best 1440p gaming monitors, the best budget and cheap gaming monitors, and the best gaming monitors under $300.

Dell G2724D

The Dell G2724D and the AOC Q27G3XMN are both excellent budget gaming monitors with a few differences. The AOC delivers better picture quality thanks to its Mini LED backlighting, letting it get brighter in HDR and display deeper blacks. On the other hand, the Dell has a different panel type with wider viewing angles, making it better for co-op gaming. The AOC has a slightly faster 180Hz max refresh rate, but the Dell has an advantage with motion handling as there's less black smearing.

Acer Nitro XV275K P3biipruzx

The Acer Nitro XV275K P3biipruzx and the AOC Q27G3XMN are both excellent gaming monitors. They each have Mini LED backlighting, and while the Acer has more dimming zones, the feature on the AOC does a better job at improving the contrast and minimizing blooming. However, the Acer gets brighter and has wider viewing angles, meaning it's better for co-op gaming. The AOC is the better choice for PC gaming as it has a faster response time with most refresh rates and lower input lag. However, the Acer is better for console gaming thanks to its 4k resolution and HDMI 2.1 bandwidth.

Samsung Odyssey Neo G7 S32BG75

The Samsung Odyssey Neo G7 S32BG75 and the AOC Q27G3XMN are both excellent gaming monitors with a few differences. They each have Mini LED backlighting, and while the Samsung has many more dimming zones, the feature on the AOC does a better job at improving the contrast without too much black crush. The AOC also gets brighter in HDR, making highlights pop more. Additionally, the AOC is the better choice for PC gaming as it has a faster response time with most refresh rates, but the Samsung is better for console gaming thanks to its 4k resolution and HDMI 2.1 bandwidth.

LG 27GR95QE-B

The LG 27GR95QE-B and the AOC Q27G3XMN are both excellent 1440p gaming monitors, but they're different in a few ways. The LG has a higher 240Hz refresh rate and supports HDMI 2.1 bandwidth, so it can take full advantage of gaming consoles and modern graphics cards. The LG also has an OLED panel that displays perfect blacks, while the AOC uses Mini LED backlighting and gets much brighter. In terms of their actual gaming performance, they each have a fast response time, but the LG has less black smearing behind fast-moving objects.

The AOC Q27G3XMN has an excellent contrast ratio. Its VA panel delivers an already-high native contrast ratio, and it gets better thanks to its full-array local dimming feature. This means it displays deep blacks next to bright highlights in dark rooms.

Full-Array

The local dimming feature performs well and has 336 small Mini LED dimming zones. The recommended Local Dimming setting is 'Medium' because the highest setting, 'Strong', is too aggressive with more blooming and black crush. The 'Medium' setting still has black crush, but it's minimal, and only certain content loses some details, like in a starfield. There's also blooming that's most noticeable when browsing the web, particularly while using a dark mode, but it isn't as bad when watching content. Even subtitles look great, with almost no blooming. However, blooming is more visible when viewing from the sides, but that's the case with most monitors anyway.

The local dimming algorithm keeps up with fast-moving objects well, but sometimes they're slow to turn off after a bright object disappears from the screen, like with subtitles. That said, this is a good overall implementation of local dimming, and it helps improve the picture quality in dark scenes.

The SDR brightness is good. It gets bright enough to fight glare, but content with small highlights is dimmer than the rest. These results are from after calibration with Game Mode off, Eco Mode on 'Standard', Color Temp. on 'User', Brightness at its max, and Local Dimming on 'Medium'. It actually gets brighter with most content with Local Dimming disabled, which is useful if you're just browsing the web and need high peak brightness, and you can see the results for it below.

The AOC Q27G3XMN has excellent HDR peak brightness. It easily gets bright enough to make highlights stand out, but small highlights are dimmed a bit. The EOTF struggles to track the PQ EOTF curve well, as all scenes are darker than intended, but because there's a sharp cut-off at the peak brightness, the monitor lets highlights get the brightest they can.

These results are in the 'DisplayHDR' HDR Mode, which you can only select when sending an HDR signal to the monitor. Local Dimming was also set to 'Medium', as 'Strong' has worse picture quality, and disabling local dimming results in a worse EOTF, as you can see here. We measured the Real Scene brightness differently than our regular methodology with a Blu-ray player, as the brightness was much lower with it. Instead, we used an HDFury Vertex Linker to force an HDR signal over HDMI from a PC, which resulted in the higher Real Scene brightness.

Using HDR on this monitor locks all gaming and picture settings, except for Overdrive, Adaptive Sync, and Overlay, which means you can still use HDR and VRR simultaneously.

The AOC Q27G3XMN has fantastic accuracy in the sRGB mode before calibration. Setting Color Gamut to 'sRGB' limits colors very well to the sRGB color space, and it also results in minimal white balance and color inaccuracies. Even the color temperature is almost spot-on with the 6500K target, but gamma is too high, meaning most content is darker than intended.

Depending on which combination of settings you use, some settings are locked out. For example, when using the 'FPS', 'RTS', and 'Racing' Game Modes, all picture settings are locked out except HDR Mode. Switching to Gamer 1, Gamer 2, or Gamer 3 unlocks some picture settings like Brightness and Gamma, but Color Temp. and Color Gamut are still locked. So to use those settings, you need to disable Game Mode and select any Eco Mode setting, except for 'Grayscale', which results in a black and white image and locks other settings. Using the sRGB mode does lock a few settings, but not the brightness, and outside of the sRGB mode, colors are oversaturated.

There are reports of a red tint with this monitor. This happens when setting Color Temp. to 'User' with its default value of 50-50-50. You either need to select another Color Temp. setting or aggressively adjust the RGB values to reduce this red tint.

The accuracy after calibration is fantastic. It improves gamma, but the main advantage of calibrating it is to get access to all picture settings and also remove the red tint, as explained in Pre-Calibration. The RGB settings are calibrated aggressively because of this red tint issue.

This monitor works as expected with the PS5, but because it doesn't support HDMI 2.1 bandwidth, it can't take full advantage of the console. It downscales a 4k signal, which results in a more detailed image than native 1440p.

macOS Compatibility

The AOC Q27G3XMN works well with macOS when using a DisplayPort to USB-C cable. It reaches its max refresh rate, and both VRR and HDR work without issues. However, over HDMI, VRR doesn't work at all and it has a max refresh rate of 144Hz. With either DisplayPort or HDMI, if you're using a MacBook and close the lid, the monitor turns off, but windows return to their original position when reopening it.

  • Frame Counter: Displays the current frame rate, but it only works with AMD graphics cards.
  • LowBlue Mode: Reduces blue light to help reduce eye strain.
  • Picture Boost: Lets you adjust the brightness and contrast of a certain section of the display.
