Key gaming benefits include:
- 200Hz refresh rate
- 0.3ms MPRT
- 1ms GtG
- Adaptive Sync
- Fast IPS response
- Low-blur motion
- QHD gaming resolution
QHD Fast IPS Display
The 2560 × 1440 QHD resolution offers significantly more detail and workspace than Full HD while remaining practical for high-refresh gaming. Fast IPS combines rapid pixel response with wide viewing angles and strong color reproduction.
Color specifications include 1.07 billion colors, approximately 120% sRGB, 92% DCI-P3, and 178° horizontal/vertical viewing angles.
HDR & Brightness
The Q27G4/WS supports DisplayHDR 400, with AOC listing approximately 350 cd/m² SDR brightness and 450 cd/m² peak HDR brightness.
Adaptive Sync
Adaptive Sync helps synchronize the monitor refresh cycle with the GPU's frame output, reducing:
- Screen tearing
- Stuttering
- Broken frames
This is particularly useful when frame rates fluctuate during demanding games.
Eye Comfort
AOC specifically lists Anti-Blue Light technology, which is designed to reduce blue-light intensity while maintaining color clarity.
The anti-glare surface also helps reduce reflections during long gaming, work, or study sessions.
Connectivity
One correction to your supplied description: the official AOC specification lists 1 × HDMI 2.0, not multiple HDMI ports.
| Port | Quantity |
|---|---|
| HDMI 2.0 | 1 |
| DisplayPort 1.4 | 1 |
| 3.5mm Headphone Out | 1 |
