AOC introduces 300Hz dual-mode monitor with up to 5K resolution

AOC has introduced the K27U3FD, a 27-inch Fast IPS monitor featuring a dual-mode design that lets users switch between 5K resolution at 75Hz and QHD mode running up to 300Hz.

When in 5K mode at 5120×2880, the display produces a pixel density of 218ppi. According to DisplaySpecifications, the Fast IPS panel on the K27U3FD supports 10-bit colour with 100% sRGB coverage, 125% sRGB volume, and 96% DCI-P3 gamut, backed by factory calibration rated at ΔE<1. AOC rates HDR brightness at 450nits alongside 350nits SDR brightness and a 1500:1 contrast ratio. Toggling over to QHD mode drops resolution to 2560×1440 while pushing refresh rates up to 300Hz with a 1ms GtG response time and Adaptive-Sync support.

Built around a Red Dot Design-awarded chassis, the monitor sits on a Pi-shaped metal stand offering 150mm of height adjustment, bi-directional pivot, ±30° swivel, and tilt from -6.5° to 23°. Port selection includes an HDMI 2.1 input with FRL6 48Gbps bandwidth, a DisplayPort 1.4 connection with DSC, and a USB-C Gen 2 port featuring DP Alt Mode alongside 96W Power Delivery. An additional USB-C data-only upstream port, one USB-C downstream port, four USB-A Gen 2 ports, and a headphone jack complete the connectivity suite.

KitGuru says: AOC's K27U3FD sounds like a nice solution for those who need a high-res display for editing, but then like to game at ultra-fast refresh rates in their downtime.
