The AOC Q27G4SMN is a 27-inch gaming monitor featuring a QHD Fast VA display panel. It delivers typical SDR levels at 450 cd/m², HDR brightness at 700 cd/m², and peak HDR brightness reaching 1200 cd/m². Certified with VESA DisplayHDR 1000, the monitor employs Mini LED backlight technology with 4608 LED particles and 1152 independently controlled zones, producing deeper blacks and brighter whites for lifelike imagery. Complementing this is Quantum Dot Color technology, which achieves 100% sRGB and 97% DCI-P3 coverage, alongside factory-calibrated color accuracy of ΔE<2, ensuring rich, precise color reproduction across its 1.07 billion displayable shades.
Performance is equally impressive. The Q27G4SMN supports a maximum resolution of 2560x1440 at an ultra-fast 300Hz refresh rate, paired with a 1ms gray-to-gray response time. Adaptive-Sync technology with AMD FreeSync support eliminates tearing and stuttering, while low input lag and specialized gaming modes such as FPS and RTS provide competitive advantages. Features like darkfield control, sniper assist, motion blur reduction, and a real-time frame counter further enhance gameplay, while customizable shortcut keys and G-Menu software allow users to tailor settings to their preferences.
Connectivity is robust, with dual HDMI 2.1 ports, DisplayPort 1.4, and audio output, ensuring compatibility with a wide range of devices. The monitor is also designed with user comfort in mind, offering TÜV-certified flicker-free technology, low blue light modes, and an ergonomic stand that supports tilt, swivel, height adjustment, and full pivot rotation. Its quick-disassembly bracket and VESA 100 x 100 mounting options add flexibility for different setups.
