This article covers AOC コンピューターモニター 67cm (27インチ) 1920 X 1080 ピクセル フル.

Overview

The AOC 27G4HA is a 27-inch Full HD (1920 × 1080) IPS gaming monitor built for competitive play. With a 200 Hz refresh rate, 1 ms GtG response, and 0.5 ms MPRT, it targets esports titles where every frame and every millisecond count. Adaptive-Sync support eliminates screen tearing and stuttering, making the gameplay experience noticeably smoother. The matte display surface reduces reflections, which is a real plus for long sessions in bright rooms. The stand offers ergonomic adjustments, letting you tilt, swivel, and change height to find a comfortable viewing angle. Positioned in the budget-to-mid tier, the 27G4HA delivers solid core specs at a price that won't break the bank.

Connectivity & Compatibility

Inputs include one HDMI and one DisplayPort. To take full advantage of the 200 Hz refresh rate, you should connect via DisplayPort, as HDMI may cap the refresh rate lower depending on the version. The monitor works with any modern graphics card that has a DisplayPort output, including the latest NVIDIA GeForce and AMD Radeon series. Adaptive-Sync will function smoothly with compatible GPUs. Console gamers can connect via HDMI, but 200 Hz operation is primarily a PC benefit. If you plan to use this monitor with a PlayStation 5 or Xbox Series X, you'll still get a decent 60–120 Hz experience, but the high refresh rate is best leveraged by a PC with a capable GPU.

Product Info

The AOC 27G4HA launched in 2025 and comes with a typical 3-year manufacturer warranty. Current street pricing hovers around the ¥30,000–¥35,000 range in Japan, making it one of the more affordable 27-inch 200 Hz monitors on the market. In the box, you'll find a power cable, an HDMI cable, and a quick-start guide. No DisplayPort cable is included, so if you plan to run at 200 Hz, you'll need to buy one separately. The monitor's market position is clearly entry-to-mid-level gaming: it lacks extras such as built-in speakers or a USB hub, focusing instead on raw display performance.

Best Use Cases

  • Competitive esports players: The 200 Hz panel and 1 ms response give a tangible edge in fast-paced shooters, fighting games, and racing sims. Motion clarity is excellent, helping you track targets without ghosting. - Budget-conscious gamers: This monitor delivers high-refresh gaming at a fraction of the cost of 4K or 240 Hz+ alternatives. It's an ideal first gaming monitor or a secondary display for a multi-monitor setup. - Office workers and students: The anti-glare coating and blue-light reduction features (adjustable via OSD) make it comfortable for daily productivity tasks, spreadsheets, and coding. If you need 4K resolution for content creation, wide color gamut for photo/video work, or HDR with high brightness, the 27G4HA won't satisfy those requirements. For pure gaming performance on a budget, however, it punches well above its weight.
