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

Will a single USB-C cable drive the 4K 60Hz picture and charge a MacBook Pro at the same time?

Yes, the upstream USB-C port delivers 90W Power Delivery with DisplayPort Alt Mode, so one cable handles 3840 x 2160 at 60Hz and up to 90W charging.

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.

Can I plug a laptop and a desktop into the monitor without swapping cables?

Two HDMI 2.0 ports and the USB-C upstream port provide three video inputs; you select the active source from the on-screen menu.
