Introduction

The AOC CQ27G1 is the most affordable 27″ 1440p 144Hz gaming monitor yet it offers an excellent image quality thanks to its high contrast ratio, high resolution, and punchy colors.

What’s more, it has plenty of gaming features such as FreeSync and 1ms MPRT which ensure a smooth performance.

Image Quality

The AOC CQ27G1 is based on a 27″ curved VA panel with true 8-bit color depth and wide 122% sRGB color gamut which makes for vibrant and rich colors.

Further, it has a high static contrast ratio of 3,000:1 which results in deep blacks. Now, the colors aren’t as accurate and consistent as they are on IPS models, but black and dark shades are much more vivid.

With a peak luminance of 250-nits, the monitor isn’t exceptionally bright, but under normal viewing conditions, it is more than bright enough.

For the optimal viewing experience out of the box, change the color temperature from ‘Warm’ to ‘sRGB’ or ‘User’.

Moving on, VA panels also have wide 178-degree viewing angles. So, unless you’re looking at the screen at a really weird angle, there won’t be any shifts in color or contrast.

1440p resolution hits the pixel density sweet spot of ~108 PPI (pixels per inch) on 27″ screens meaning that you’ll get plenty of screen real estate as well as sharp details and text.

Lastly, the AOC CQ27G1 has a flicker-free backlight and an integrated low-blue light filter allowing you watch the screen for hours without having to worry that it will cause you eye strain or headaches.

All in all, you get an amazing image quality for the price with deep blacks, gorgeous colors, and crisp details. If you have too strong lighting in your room, you may want to dim the lights and shut the drapes for the best viewing experience as it will make the deep blacks stand out even more.

Performance

The performance of the AOC CQ27G1 is also exceptionally good for the price.

Input lag is just below 4ms of delay which is imperceptible while the 144Hz refresh rate makes for a responsive and enjoyable gaming experience.

As it’s the case with all high refresh rate VA panel gaming monitors, there is noticeable smearing of fast-moving objects when dark pixels are predominant in the picture, but it’s tolerable – unless you’re a hardcore FPS gamer in which case you’d be better off with a 240Hz display at this price range anyway.

The AOC CQ27G1 display is equipped with the 1ms MPRT motion blur reduction technology which can via backlight strobing reduce the amount of noticeable trailing in fast-paced games.

Enabling 1ms MPRT, however, limits the monitor’s maximum brightness. Luckily, using the MBR setting in the OSD (On-Screen Display) menu of the monitor, you can manually adjust the frequency of the backlight strobing from 0 to 20 in increments of 1 until you find the perfect trade-off between motion clarity and picture brightness for you.

1ms MPRT cannot be active at the same time as AMD FreeSync.

When you enable FreeSync, the monitor will change its refresh rate dynamically matching the GPU’s frame rate. This will eliminate screen tearing and stuttering for good as long as your FPS (Frames Per Second) rate is within 48-144Hz/FPS which is the variable refresh rate (VRR) range of the AOC CQ27G1.

While the monitor is not certified by NVIDIA as G-SYNC compatible, you can use FreeSync with compatible NVIDIA cards without any issues.

Features

In the OSD menu of the AOC CQ27G1 curved monitor, you will find plenty of additional features. The menu is well-organized, but navigation through it is a bit tedious as there are four hotkeys rather than a joystick.

Alternatively, you can download the AOC G-Menu desktop application and make some of your adjustments there.

Gaming features include Shadow Boost (increases visibility of objects in the dark), Game Color (quick color saturation adjustments), Frame Counter, Low Input Lag (bypasses certain image post-processing for minimal input lag), custom crosshairs, and picture presets (three custom modes plus FPS and RTS presets).

There are four pixel response time overdrive options (Off, Weak, Medium, and Strong). For desktop use and most video games, we recommend using the Medium preset. ‘Strong’ may provide a better performance in certain games, but in most cases, it will introduce too much pixel overshoot i.e. reverse ghosting.

Available standard adjustments include brightness/contrast, input source, color temperature (manual red, green, and blue color adjustments), and three gamma presets. There’s no hue/saturation option, but that can be tweaked via the Game Color feature or in your graphics card’s drivers settings.

Design & Connectivity

The build quality of the AOC CQ27G1 144Hz monitor is excellent considering the price. You get thin bezels and a sturdy metal stand which even offers height adjustment up to 130mm, swivel by +/- 35°, and tilt by -4°/22°. Alternatively, you can mount the screen on a third-party stand via the 100x100mm VESA pattern.

Connectivity options include two HDMI 2.0 ports, DisplayPort 1.2, and a headphones jack. FreeSync is supported over all three display connectors up to 144Hz at 2560×1440. The monitor also supports 1440p 120Hz on Xbox One X.

Price & Similar Monitors

The AOC CQ27G1 price amounts to only $250 which makes it the cheapest 27″ 1440p 144Hz gaming monitor.

It offers exceptional value for the price and we highly recommend it. You also get a three-year warranty on dead pixels and advance replacement and a one-year warranty on accidental damage.

However, if you have a bit higher budget, you may want to consider the following alternatives as well:

  • AOC AG273QCX (~$300) – with entry-level HDR400, a higher peak brightness (400-nits), and more connectivity options. Alas, it has certain flickering issues when using FreeSync with NVIDIA cards. If you have an AMD card though, it’s perfect.
  • MSI MAG271CQR (~$350) – with a higher peak brightness (400-nits), a USB hub, and a stable G-SYNC performance.

In case the AOC CQ27G1 is not available in your region or if it’s overpriced, you may want to have a look at the Samsung C27JG50 and C27JG56 budget 1440p 144Hz curved models.

If you want a 27″ 1440p 144Hz display with an IPS panel for a faster response time speed and more accurate colors, check out the Nixeus EDG27S v2 (~$400) and the LG 27GL850 (~$500). However, keep in mind that IPS models have disadvantages of their own including IPS glow and lower contrast (1,000:1).

Conclusion

Overall, you won’t be disappointed with the AOC CQ27G1 for the price paid. In fact, you’ll be quite pleasantly surprised.
