27″ models with 2560 x 1440 (QHD or 1440p) resolution are very popular as diverse choices for both work and play. The AOC Q27G4X provides this, with a 180Hz IPS panel designed to appease gamers. The monitor adopts plenty of dark matte plastics with fairly compact hexagonal stand base – absent are any red plastic elements as found on some older models. The top and side bezels retain the dual-stage bezel design with slim panel border flush with the rest of the screen, plus a thin hard plastic outer part. The OSD (On Screen Display) is controlled by buttons beneath the bottom bezel, at the right side.

The front

A 27″ 2560 x 1440 (QHD or 1440p) IPS-type panel features with support for a 180Hz refresh rate and Adaptive-Sync. This allows VRR technologies such as Nvidia ‘G-SYNC Compatible’ and AMD FreeSync to be used, with 48 – 180Hz VRR range plus LFC. A matte anti-glare screen surface is used with a 1000:1 static contrast ratio, 178°/178° viewing angles and 10-bit colour specified. A flicker-free WLED backlight provides a 400 cd/m² typical maximum luminance and 124.7% sRGB (93.9% DCI-P3) colour gamut, for a boost to vibrancy without strong oversaturation. A 0.5ms MPRT response time is specified using the MBR (Motion Blur Reduction) strobe backlight setting, alongside a 1ms grey to grey response time. As usual, take such figures with a pinch of salt.

The monitor is VESA DisplayHDR 400 certified, allowing a basic HDR10 response. It doesn’t offer particularly high brightness or have an overly wide gamut by HDR standards, nor is local dimming specified. But it can put what it does have to potentially good use alongside 10-bit colour processing. Low Blue Light (LBL) settings are also included to promote a more relaxing viewing experience. The screen attaches to the stand via a quick-release mechanism and can be removed to reveal 100 x 100mm VESA holes for alternative mounting. The stand is fully adjustable including height (130mm or 5.12 inches) adjustment and pivot into portrait. The ports face downwards and include; DP 1.4, 2 HDMI 2.0 ports, a 3.5mm headphone jack and AC power input (internal power converter). Low powered speakers are included for basic sound output.
