Gaming monitor evaluation: AOC Q27G40XMN's 27-inch Mini LED shows off impressive color depth and illumination in gaming
The AOC Q27G40XMN monitor stands out in the market for its exceptional performance in handling High Dynamic Range (HDR) content, offering a premium HDR experience at a budget-friendly price.
One of the key features that sets the Q27G40XMN apart is its advanced mini LED backlighting with full-array local dimming (FALD), a rarity at its price point. With 1,152 mini LED dimming zones, the monitor provides precise backlight control, ensuring bright highlights and deep blacks without the heavy blooming artifacts commonly seen in edge-lit displays.
The Q27G40XMN's HDR image quality is impressive, boasting a wide 97% DCI-P3 colour gamut, delivering vibrant and accurate colours ideal for HDR content. Its high native contrast ratio (around 4,600:1) further enhances shadow detail and reduces haloing effects around bright objects.
The monitor's 27-inch 1440p (QHD) resolution offers a good balance of sharpness (108 PPI) and performance without needing scaling, making it suitable for both video and gaming HDR content. The VA panel provides wide 178° viewing angles and a very fast 1ms gray-to-gray response time, minimizing motion blur and ghosting during fast scenes, which benefits HDR games and videos.
The Q27G40XMN's high dynamic range performance is combined with a smooth 180 Hz refresh rate and low input lag, making it an excellent choice for HDR gaming as well as general HDR media consumption.
Compared to OLED HDR monitors, while it lacks infinite contrast and pixel-level lighting, it stands out as a cost-effective alternative offering strong HDR brightness, colour accuracy, and dynamic range with minimal blooming—making it suitable for users who want a premium HDR experience at a budget-friendly price.
The Q27G40XMN's brightness is truly impressive, with more than 1,300 nits available. Its local dimming can be set to medium or strong, ensuring a lot of punch to highlight areas. The colour anomalies noted in Standard Dynamic Range (SDR) mode have vanished for HDR on the Q27G40XMN, and it hits the tone-map transition perfectly at 75% brightness.
The Q27G40XMN uses Mini LED and Quantum Dot technology, and its default HDR mode (Game mode) has a visually perfect grayscale with no errors greater than 2dE.
In summary, the AOC Q27G40XMN's large number of local dimming zones, strong native contrast, high peak brightness, wide colour gamut, and solid panel performance collectively provide an excellent HDR viewing experience, especially valued in its competitive price segment. If you can't afford an OLED or need a really bright monitor, the Q27G40XMN is one of the best performing monitors out there.
