AOC has introduced the 41.5-inch AG421UDA OLED Smart Display in China, positioning it as a strong competitor to traditional TVs and high-end gaming monitors. The device runs on Android 14, turning it into a complete entertainment and productivity hub rather than just a standard display. The company has not yet revealed the pricing or availability details.

AOC AG421UDA Specifications
The AG421UDA features a 3840×2160 UHD resolution, a 144Hz variable refresh rate, and a native 0.1ms gray-to-gray response time. The display uses an RWBG four-primary-color OLED panel with over 30 million self-emissive pixels. It supports native 10-bit color depth and covers 98.5% of the DCI-P3 color gamut. The display supports Dolby Vision, HDR10+, and HLG for dynamic HDR content.
The smart display runs on a quad-core Arm Cortex-A55 CPU paired with an Arm Mali-G57MC2 GPU. It has 4GB of DDR4 memory and 32GB of eMMC storage. It includes Wi-Fi 6, Bluetooth 5.2, and runs a simplified Android 14 user interface optimized for large screens. AOC includes a Bluetooth remote with voice control support and a dedicated Bilibili shortcut key.


AOC preloads the device with Chinese streaming apps like Bilibili, Douyu, and Huya. It also includes an exclusive app store with curated media, education, and productivity apps. The display supports wireless screen casting from smartphones and laptops. The onboard DeepSeek AI assistant handles voice commands and system navigation.
The AG421UDA comes with a 2.1-channel speaker system that includes dual 10W speakers and a 30W subwoofer. It holds Dolby Atmos certification for enhanced surround sound.
For connectivity, the monitor includes two HDMI 2.1 ports, two HDMI 2.0 ports, one USB 2.0 (480Mbps), one USB 3.0 (5Gbps), a 3.5mm headphone jack, S/PDIF optical audio output, and an RJ45 Ethernet port.
AOC also includes gaming-focused features like a built-in Game Bar and support for Auto Low Latency Mode (ALLM). The display is certified for both Nvidia G-Sync Compatible and AMD FreeSync Premium, reducing tearing and stutter during gameplay.
In related news, AOC has also introduced two new gaming monitors recently, the U32G4U featuring a 4K 160Hz display with dual-mode support for FHD 320Hz, and the Q27G41ZDF equipped with a 27-inch 2K QD-OLED panel offering a 240Hz refresh rate..
