Description
AOC AG346UCD arrives as a 34" (86.4 cm) curved QD-OLED gaming monitor designed to impress with a 3440 x 1440 Wide Quad HD resolution and a blistering 0.03 ms GTG response time.
The AOC AG346UCD uses a QD-OLED OLED panel with W-LED backlighting to deliver an exceptional typical brightness of 1000 cd/m² and a deep contrast ratio of 150000:1, while supporting DisplayHDR 400 True Black for richer HDR scenes.
With a native 21:9 aspect ratio and a 1800R curvature, the ultrawide 34" screen offers immersive horizontal workspace (80.1 cm) and vertical viewing of 33.7 cm, supported by nearly 1.073 billion colours and coverage of DCI-P3 99.3%, sRGB 139.1% and Adobe RGB 97.8% for colour-critical tasks.
Gamers benefit from a maximum refresh rate of 175 Hz, NVIDIA G-SYNC and AMD FreeSync Premium compatibility (48–175 Hz), VESA Adaptive Sync support, and low input lag with HDR and flicker-free/low-blue-light technologies for long sessions.
The monitor is also practical for everyday setups: it includes two HDMI 2.0 ports, one DisplayPort 1.4, a USB 3.2 Gen 1 hub (3x Type-A downstream, 1x Type-B upstream), a 3.5 mm headphone jack, built-in 2x speakers (16 W RMS) and convenient cable management with a Kensington lock slot. VESA 100 x 100 mm mounting is supported and the detachable stand allows 13 cm height adjustment, tilt and ±16° swivel.
Its frameless design in black/grey, robust 3‑year warranty and compliance with major safety and environmental standards (CE, FCC, RoHS, REACH, WEEE) position the AOC AG346UCD as a premium gaming display that also serves creators and productivity users.
The monitor excels in scenarios such as immersive racing and flight sims, competitive FPS play with ultra-low latency, and video/photo editing that requires wide colour gamut and high contrast. Included cables (AC, HDMI, DisplayPort, USB) and thoughtful ergonomics make it ready for a high-performance desktop setup.
