The AOC AGON PRO AG276QZD2 Gaming Monitor combines QD-OLED display technology, QHD resolution, and a high refresh rate for responsive gaming and detailed visuals. Its 26.5-inch panel delivers 2560 × 1440 resolution, a 240Hz refresh rate through DisplayPort, and a 0.03ms GtG response time. VESA DisplayHDR True Black 400 certification, Adaptive Sync, and a wide colour gamut make it suitable for competitive gaming and immersive entertainment.
Overview
Part of AOC's AGON PRO gaming monitor range, the AG276QZD2 is designed for gamers who value fast response, smooth motion, and rich image contrast. Its flat QD-OLED panel combines quantum dot colour technology with OLED pixel-level lighting to deliver deep blacks and vivid colours. The 16:9 QHD display provides a detailed workspace for gaming, streaming, and everyday computer use.
QD-OLED Display Technology
The monitor's Quantum Dot OLED panel combines OLED contrast characteristics with quantum dot colour reproduction. Each pixel produces its own light, allowing dark areas to appear genuinely black without a conventional backlight.
- QHD resolution: 2560 × 1440 pixels provide detailed images for gaming and multimedia.
- QD-OLED panel: Combines rich contrast with a wide colour gamut.
- High contrast: A specified 1,500,000:1 static contrast ratio supports clear differentiation between dark and bright content.
- Wide colour coverage: Covers 100% of sRGB and approximately 98.5% of DCI-P3 under the manufacturer's stated measurement standards.
- Wide viewing angles: The specified 178-degree horizontal and vertical viewing angles support viewing from different positions.
240Hz Refresh Rate and Fast Response
The AG276QZD2 supports a refresh rate of up to 240Hz through DisplayPort 1.4, helping compatible gaming systems display motion smoothly. Its 0.03ms grey-to-grey response time supports rapid pixel transitions, making it well suited to fast-paced games where motion clarity matters.
For HDMI connections, the manufacturer's specification sheet lists QHD operation up to 144Hz. Achieving 2560 × 1440 at 240Hz requires a compatible DisplayPort connection and graphics hardware that supports the required display mode.
HDR True Black 400
VESA DisplayHDR True Black 400 certification supports HDR presentation with deep blacks and enhanced highlight detail in compatible games and video content. The monitor's specified brightness varies with the displayed image and HDR measurement window, reaching up to 1000 cd/m² under the manufacturer's stated HDR test conditions.
HDR performance depends on the content, software, operating system settings, and selected monitor mode.
Adaptive Sync and Gaming Features
Adaptive Sync helps synchronize the monitor's refresh rate with compatible graphics hardware to reduce screen tearing and uneven motion. AOC also lists NVIDIA G-SYNC Compatible support for compatible configurations.
Additional gaming features include configurable game modes, Sniper Scope, Dynamic Dial Point, RGB Light FX, and AOC G-Menu software. Picture-in-Picture and Picture-by-Picture functions allow supported sources to be displayed simultaneously.
Ergonomic Stand and Design
The included adjustable stand supports height adjustment, tilt, swivel, and pivot rotation, helping users position the display for their desk and viewing preferences. Its compact esports-oriented base includes cable management to help keep the desktop organized.
The monitor also supports VESA 100 × 100 mm mounting for compatible monitor arms and wall-mount systems.
