BenQ MA320U 31.5" 4K UHD Monitor for MacBook
PRODUCT DESCRIPTION
BenQ MA320U 31.5" 4K UHD Monitor for MacBook (MA320U) - 3 Year Local Warranty
A 32-Inch Mac Companion Screen, Colour-Matched to macOS
The MA320U is built around the MacBook rather than adapted to it. M-book and Display P3 colour modes line the panel up with what macOS shows on the notebook's own screen, over 99% sRGB and 97% Display P3 and 1.07 billion colours, so an image does not change character when it moves to the big display. The 3840 x 2160 panel at 31.5 inches gives 140 pixels per inch — enough desktop area for a timeline, a browser and a chat window side by side without resorting to two monitors.
One USB-C Cable: 4K Video, 90W Charging and a USB Hub
A single USB-C cable carries display signal, USB data and 90W of Power Delivery back to the MacBook, replacing a charger, a dock and a video lead with one connector. Two USB-A downstream ports and a USB-C downstream port take a keyboard, a card reader or an SSD, and two HDMI 2.0 inputs stay free for a Mac mini, an iPad, a console or a corporate Windows laptop. On a hot desk or a shared studio bench in Singapore, plugging in once is the difference between working and configuring.
Nano Matte Panel, 550 Nits and DisplayHDR 600
Nano Matte is BenQ's low-haze anti-glare coating: it diffuses ceiling lights and window glare without the sparkle coarse matte finishes give to text, which matters on a screen this size. Brightness is rated 550 nits with 1300:1 native contrast, and the panel carries VESA DisplayHDR 600 certification alongside HDR10, so highlights in graded footage and HDR photos have real headroom. If your room is light-controlled and you prefer a glossy look, the MA320UP is the same monitor with a Nano Gloss surface.
Ergonomics, Auto Pivot and Display Pilot 2
The stand provides 115 mm of height adjustment, -5 to 20 degrees of tilt, 15 degrees of swivel each way and a 90-degree pivot, with Auto Pivot turning the image as the panel rotates. VESA 100 x 100 mm mounting takes an arm where desk depth is tight — worth planning for, since a 31.5-inch panel wants a little more viewing distance than a 27. Display Pilot 2 adds desktop partitioning, hotkeys and ICCsync, which keeps the macOS colour profile in step with the monitor's active colour mode.

Compatibility & Installation
MacBook and Mac desktop connection
A MacBook Air or MacBook Pro connects with one USB-C cable for 4K video, data and 90W charging. A Mac mini, Mac Studio, iPad, iPhone or console connects over either HDMI 2.0 input. M-book and Display P3 colour modes keep the external screen consistent with the MacBook's own panel.
Windows and mixed desks
Any Windows notebook with USB-C DisplayPort Alt Mode docks and charges the same way, and the HDMI inputs accept any standard source, which suits a desk shared between personal and corporate machines.
Mounting, orientation and desk depth
The stand adjusts 115 mm in height, tilts -5° to 20°, swivels 15° each way and pivots 90° with Auto Pivot. VESA 100 x 100 mm mounting is provided. At 31.5 inches allow a deeper desk or an arm so the whole panel sits in comfortable view.
Software
BenQ Display Pilot 2 provides desktop partitioning, hotkey control and ICCsync for macOS colour profile synchronisation.
Elsewhere in the range
For the same size in a glossy finish, see the MA320UP; for Thunderbolt 4 and 120 Hz, the MA320UG; for a 27-inch desk, the MA270U.

Frequently Asked Questions — BenQ MA320U
What do the U, UP and UG suffixes mean?
Plain U — this model — is the base specification: Nano Matte panel, 90W USB-C docking, 60 Hz. UP (MA320UP) is the same monitor with a Nano Gloss panel. UG (MA320UG) steps up to Thunderbolt 4 docking with 96W charging, daisy-chain out and a 120 Hz Nano Gloss panel. The 27-inch models follow the same pattern, with MA270S as the 5K Thunderbolt option.
Nano Matte or Nano Gloss?
Nano Matte, fitted here, diffuses overhead lighting and window glare and is the safer choice in a typical bright office. Nano Gloss (MA320UP) gives deeper blacks and a more saturated look in a room where lighting is controlled. Resolution, gamut and ports are otherwise identical.
Will one cable charge my MacBook?
Yes. The upstream USB-C port supplies 90W of Power Delivery with 4K video and USB data on the same cable, which covers a MacBook Air or 14-inch MacBook Pro. A 16-inch MacBook Pro at sustained full load may draw more than 90W and simply charges more slowly.
Is 31.5 inches too big for 4K?
At 31.5 inches, 4K works out to 140 PPI against 163 PPI on a 27-inch 4K panel, so everything is physically larger at the same resolution. It suits people who want more workspace rather than finer text; for maximum sharpness at 27 inches look at the MA270S at 5K.
Does it colour-match my MacBook?
It provides M-book and Display P3 modes and covers 99% sRGB with 97% Display P3, and ICCsync keeps the macOS colour profile aligned with the monitor's active mode.
Can I mount it on an arm or use it in portrait?
Yes. VESA 100 x 100 mm mounting is provided, and the supplied stand pivots 90° with Auto Pivot rotating the image. On a 31.5-inch panel, check your arm's weight rating against the 9.1 kg net weight.
What else can I connect?
Two HDMI 2.0 inputs plus the USB-C upstream, with two USB-A and one USB-C downstream ports acting as a hub for peripherals.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every BenQ MA320U sold by SourceIT carries the 3 year BenQ Singapore local warranty on monitors, and a GST invoice is issued with every unit.
