Mac-Ready 4K Display

The BenQ MA320U is a 31.5 inch 4K monitor built for MacBook users who want a single-cable workspace. It covers 99% sRGB and 97% P3 colour spaces with Nano IPS technology and meets DisplayHDR 600 certification. Factory colour matching keeps Mac output consistent without extra calibration steps.

One-Cable Docking

A USB-C port delivers 90 W power delivery, DisplayPort Alt Mode video and 5 Gbps data through one cable, removing the need for a separate dock or power brick. Two additional USB 3.2 Gen 1 downstream ports provide 7.5 W and 15 W charging for peripherals. Two HDMI 2.0 inputs allow secondary devices such as consoles or a work laptop.

Quiet 45 W Operation

Typical power draw is 45 W and peaks at 250 W when all USB ports supply maximum current, while sleep mode stays below 0.5 W. The flat panel runs without active cooling so the monitor adds no fan noise to a quiet studio. An adjustable foot lets you set height and tilt for comfortable long sessions.

Questions about this item

Does the monitor cover the P3 colour space used in macOS and video work?

The Nano IPS panel reaches 97% P3 and 99% sRGB, and the Mac Color Matching feature aligns the monitor’s output with macOS system colours.
