AOC Agon Pro AGP277KXM: 5K 180Hz Mini LED Monitor

The AGP277KXM utilizes a Fast IPS panel with a resolution of 5120×2880. This configuration results in a pixel density of 218 pixels per inch, which is a 33% increase over standard 4K displays. However, the raw pixel count is 78% higher than 4K, requiring significant GPU power to drive the image, even at the monitor's base refresh rate. AOC notes that the panel supports a dual mode feature, allowing users to switch to QHD (2560×1440) at 330Hz for those prioritizing motion smoothness over resolution. The manufacturer rates the response time at 1ms (GtG), though real-world performance remains to be verified by independent testing.

Brightness and contrast are key differentiators for this Mini LED implementation. The monitor carries VESA DisplayHDR 1400 certification, with a typical SDR brightness of 450 nits. HDR output reaches approximately 1,200 nits, stretching to 1,600 nits at peak. The 2,304 local dimming zones aim to provide contrast levels comparable to OLED technology. Color accuracy is also emphasized, with 98% coverage of both DCI-P3 and Adobe RGB color spaces. AOC promises factory calibration that keeps the average Delta E below 1 in sRGB.

Connectivity options include two HDMI 2.1 ports, one DisplayPort 2.1 (UHBR20), and a USB-C port with DP Alt Mode. AOC states that Display Stream Compression is required to achieve 5K at 180Hz across all connection types. The monitor also includes three USB-A ports and a built-in KVM switch, allowing users to share peripherals between two systems. Currently, there is no information regarding pricing or availability outside of China, but the complete specifications sheet and gallery are available on the regional AOC website.
