AOC has just announced its most advanced 31.5in 4K display to date, based on a 4th-gen QD-OLED panel that has an anti-reflective coating The AOC Agon Pro AG326UZD2 promises support for wide colour gamuts, while also bringing all the usual benefits of OLED for gaming.
While its 4th-gen tech isn’t as fancy as the latest 5th-gen panels with their RGB stripe patterns largely solving problems with text fringing, a 4th-gen QD-OLED is perfectly fine for most users, providing a leap in visual quality and clarity compared to traditional LCD-based panels. That means you get per-pixel local dimming, as well as deep, pure blacks, and lightning-fast response times. AOC also makes some bold claims about its colour coverage, saying that the AG326UZD2 offers of 99.7% of the DCI-P3 gamut, 140.7% of sRGB cover, and 96.9% of Adobe RGB gamut coverage.
The Agon Pro AG326UZD2 also features the brand’s latest AntiReflection 3.0 coating, said to reduce reflections without the haze typically associated with matte finishes. While it’s unclear whether this is equivalent to MSI’s DarkArmor Film, AOC indicates that it preserves the vivid and punchy image quality for which QD-OLED panels are known.
It certainly represents a significant step forward compared to its predecessor, the AG326UD. Refresh rates have jumped from 165Hz to 240Hz, allowing clearer vision in fast-paced games, while the DisplayHDR rating has improved to True Black 500. Thanks to its new panel technology, this model can reach 450nits at 10% APL and up to 1,000nits at 3% APL, with full-screen SDR brightness at 250nits. This is bright enough to give you punchy highlights contrasted with deep blacks.
For this model, AOC went with a flat 4K (3840×2160) design, so it will be equally at home with precise 3D and CAD work as it is with gaming. There’s a built-in KVM switch as well, so you can easily switch between multiple devices using the same display and peripherals. Gamers will also appreciate the sharp 139 PPI pixel density, thanks to its 4K resolution, as well as its fast 0.03 GtG pixel response times, and Nvidia G-Sync support to remove tearing effects in fast motion.
Moving to connections, the AG326UZD2 offers two HDMI 2.1 ports supporting 4K at 120Hz – handy for PS5 and Xbox Series consoles, one DisplayPort 2.1 (UHBR 20) input supporting 4K at 240Hz, plus a USB-C socket with 65W power delivery. These are complemented by dual 8W speakers, a 3.5mm audio out, and a two-port USB hub.
In terms of ergonomics, you will find the brand’s esports stand design, offering 150mm height, -5° to +23° tilt 16° swivel, and 90° pivot adjustments, on top of the usual 100x100mm VESA mount compatibility.
The Agon Pro AG326UZD2 will be available from April 2026 at £799 MSRP, backed by a three-year warranty covering OLED burn-in.
