AOC U27G4 Features
The U27G4 is equipped with a Fast IPS panel that offers a precise 3840×2160 resolution at 160Hz or a smoother 1920×1080 at 320Hz. It has a peak brightness of 450 nits, a contrast ratio of 1000:1, and an ultra-fast 1ms gray-to-gray (GTG) response time. The display supports a 10-bit color depth (8-bit + FRC) and covers 100% of the sRGB and 95% of the DCI-P3 color gamut, which ensures that visuals are both vibrant and accurate. Additionally, AOC has incorporated Adaptive-Sync technology, with AMD FreeSync support, to remove screen tearing and stuttering, improving the smoothness of gameplay.
Connectivity and Gaming Features
When it comes to connectivity, the monitor includes two HDMI 2.1 ports, one DisplayPort 1.4 input, and a 3.5mm headphone jack. AOC has included various gaming features such as its exclusive G-Menu software, Game Color tuning, Shadow Control, Dynamic Crosshair, and Overdrive. For first-person shooter gamers, the monitor offers low input lag and Motion Blur Reduction Sync (MBR Sync) to enhance clarity in action sequences. Picture-in-Picture (PIP) and Picture-by-Picture (PBP) modes allow users to multitask by showing two signal sources at once.
Design and Ergonomics
Design-wise, the U27G4 features a sleek, gaming-oriented look with ultra-thin bezels of just 1mm, along with a narrow 6.2mm black border. The black-red color scheme boosts its esports vibe. The ergonomic stand allows for height adjustments of up to 130mm, bi-directional pivoting, tilting from -5 to 23 degrees, and a 30-degree swivel, ensuring a comfortable and customizable setup. Furthermore, the monitor is VESA 100x100mm compatible for those who prefer wall mounting.
AOC has also received VESA DisplayHDR 400 certification for this model, which guarantees deeper blacks and brighter whites, although it doesn’t match the contrast levels of higher-end HDR displays. The monitor includes flicker-free technology and a hardware-based low-blue light panel designed to minimize eye strain during prolonged gaming sessions.
