AOC has launched its latest gaming monitor, the Agon AG277QSD, in China. The monitor is priced at 3,160 yuan ($472), while local subsidies bring the price down to 2,799 yuan ($418). It features a 26.5-inch 1440p QD-OLED panel with a high refresh rate and factory color calibration, including dedicated calibration for HDR content.

AOC Agon AG277QSD Specifications
The monitor is built around an EL Gen.3 QD-OLED panel. This generation uses a five-layer tandem light-emitting structure, which is a hardware update from the previous four-layer design. By utilizing three blue layers and two green layers, the panel is designed to increase luminous efficiency by 30% and extend the display’s overall lifespan. To help manage heat and reduce the standard risk of OLED burn-in, AOC has also included a graphene-based thermal cooling system.

For gaming, the AG277QSD features a 2560 x 1440 resolution with a 320Hz refresh rate and a native 0.03ms gray-to-gray response time. It comes with Nvidia G-Sync Compatible certification and supports Display Stream Compression (DSC) through both HDMI and DisplayPort. AOC also equips the monitor with flexible display scaling options for competitive gaming, including a 24.5-inch viewing mode and a 4:3 mode at 1280 x 960 with pixel-to-pixel mapping.
The company says that the AG277QSD is the first monitor to include factory HDR color calibration. Each unit ships with an individual calibration report, and AOC claims an average Delta E of less than 2 in DisplayHDR mode (which accounts for brightness deviation) and less than 1 in the standard DCI-P3 mode. The 10-bit panel covers 99% of the DCI-P3 color gamut and includes a 12-axis color adjustment system for manual tuning.
The display is VESA DisplayHDR True Black 500 certified. It can reach 515 nits of brightness. The screen also features a DarkShield Black anti-reflective coating, which is designed to cut down ambient light reflections by 40% compared to older QD-OLED panels while providing a 3H hardness rating for better scratch resistance.

Port selection includes two HDMI 2.1 ports (48Gbps), one DisplayPort 1.4 (32.4Gbps), a three-port USB 3.2 Gen 1 hub, and a 3.5mm audio jack. The monitor sits on an ergonomic stand with height, tilt, swivel, and pivot adjustments. Additionally, it includes a built-in retractable headphone hanger, a mouse cable clip, and rear ambient lighting that syncs with Windows 11 Dynamic Lighting.
In related news, Xiaomi has recently launched the Redmi A27U 2027 monitor with a 4K 120Hz display, 90W USB-C, and a dedicated Apple color mode, while AOC introduced a new 49-inch 240Hz QD-OLED ultrawide curved monitor with 90W USB-C charging.
