AOC has launched a new 4K gaming monitor in China, the U32G5D. It features a 31.5-inch Penta Tandem QD-OLED panel that's based on EL 3.0 technology.

With a peak brightness of 450 nits, the monitor should offer an enhanced HDR experience, and as the brand highlights, it has DisplayHDR True Black 400 certification.

The monitor supports Adaptive Sync and, with a 0.03 ms GtG response time, it should deliver a smooth, tear-free gaming experience. There's a decent selection of ports as well, including:

• 1x DisplayPort 2.1
• 2x HDMI 2.1
• 2x USB 3.2 Gen 1 Type-A
• 1x USB-B upstream
• 1x 3.5mm audio

Other highlights include 100% sRGB and 99% DCI-P3 color coverage, an adjustable stand , VESA mount support (Wali triple-monitor stand curr. $69.98 on Amazon), and multiple gaming-focused features like PIP/PBP and game-based modes. In China, the promotional launch price of this QD-OLED gaming monitor is CNY 3,498, around $524. AOC has yet to share details on the global availability of the U32G5D.
