AOC launches 31.5-inch 4K QD-OLED monitor in China
AOC has launched the U32U4 monitor in China, using QD-OLED technology from Samsung Display.
Its 31.5-inch screen has 4K resolution and a 120Hz refresh rate, making it suited to both professional color work and gaming.
A five-layer OLED design spreads electrical load across the panel, which AOC says can support high brightness while reducing strain on the organic materials.
The monitor also has a graphene-based heat-dissipation layer intended to reduce the risk of burn-in, a concern with OLED screens.
Its color features target accurate work, including native 10-bit color, broad color coverage and factory calibration.
HDMI 2.1, DisplayPort and two USB-C ports, along with a built-in KVM switch, support connecting devices and multitasking.
