AOC has unveiled the AGON AG275UXM2, a 68.6 cm (27-inch) Mini LED gaming monitor that packs 2,304 local dimming zones and a dual-mode trick: run it at native 4K 160Hz for sharp visuals, or drop to 1080p and crank the refresh rate up to 320Hz when competitive frame rates matter more. Powered by 9,216 mini LEDs paired with Quantum Dot film, the panel is VESA DisplayHDR 1400 certified and hits a peak brightness of 1,600 nits, while SDR tops out at 600 nits.
The Fast IPS panel covers 98% of DCI-P3 and 100% of sRGB with a factory-calibrated Delta E below 1, 10-bit color depth, and a 1,000:1 static contrast ratio. AOC specs the response time at 1ms gray-to-gray, dropping to 0.5ms MPRT at 4K and 0.3ms MPRT at 1080p. Adaptive sync and AMD FreeSync support are included for variable refresh rate gaming.
Connectivity is solid for a gaming display. Two HDMI 2.1 ports and one DisplayPort 1.4 handle video input, while a USB-C port delivers DisplayPort Alt Mode and 65W power delivery. Three USB-A downstream ports round out the I/O, and a built-in KVM switch with picture-in-picture and picture-by-picture modes makes it practical for multi-device setups. The stand offers full tilt, height, swivel, and pivot adjustments, plus a headphone hook and rear RGB ambient lighting.
The AG275UXM2 is an upgrade over AOC's 2024 AG275UXM, adding improved Mini LED backlighting, higher brightness, and the dual-mode refresh rate feature. It is currently available only in China for 3,999 yuan, roughly $550 (€505), with no confirmed timeline for a global release.
Linux users eyeing the AG275UXM2 for HDR gaming should note that KDE Plasma 6.6 (due February 2026) continues to refine its Wayland HDR pipeline, while Valve's gamescope compositor can drive HDR10 output with its --hdr-enabled flag, though both paths still require AMD Radeon graphics and kernel 6.8 or newer for reliable results. FreeSync VRR works natively on Wayland compositors including KDE Plasma and Sway without the multi-monitor limitations of X11, and the DisplayPort 1.4 input is the most dependable connection for variable refresh rate on Linux. For color-critical work, DisplayCAL paired with ArgyllCMS can generate ICC profiles that take advantage of the factory-calibrated Delta E, and ddcutil enables DDC/CI control of brightness, input switching, and color settings from the command line, though some AOC models have historically required enabling DDC/CI in the OSD and connecting over DisplayPort for reliable communication.
