The full review

Where it fits

The BenQ RD320UA is a 31.5 inch IPS monitor with a maximum resolution of 3840x2160. It refreshes at 60 Hz and lists a 5 ms GtG response time. Its strengths are docking, the matte panel finish and the stand. Its weaknesses are motion and HDR. It makes most sense on a desk where one cable links a laptop to the screen.

Docking and connectivity9/10

The monitor can dock a laptop over a single USB-C connection. The USB-C input carries video through DisplayPort Alt Mode, data and 90W of Power Delivery. A 90W figure leaves room to power a laptop from the monitor while it sends video.

Behind that sits a USB hub. There is a USB Type-A downstream port and two USB-C downstream ports running at 10 Gbps. HDMI and DisplayPort video inputs cover machines that lack USB-C.

The monitor also has a built-in KVM switch. With the KVM and the extra downstream ports, it suits a desk that connects a laptop and a second computer to one screen.

Panel and finish7/10

The panel is IPS, and BenQ lists 98% P3 colour gamut, 2000:1 native contrast and 400 nits typical brightness. Those figures point to a capable general-purpose panel for documents, browsing and colour-aware work.

Owners praise the anti-glare Nano Matte finish. That matters most in a room with windows or overhead lighting.

The monitor supports HDR10 and VESA DisplayHDR 400. Owners are not impressed by the result: weak HDR performance is a recurring complaint. If HDR video or games matter to you, treat the HDR support as a checkbox feature rather than a reason to buy.

Sharpness7/10

A 3840x2160 resolution on a 31.5 inch panel gives a large workspace with fine detail. Text and interface elements have plenty of pixels to draw on, and the size leaves room for several windows side by side. The screen is big, so it suits a desk with enough viewing distance.

Ergonomics8/10

The monitor ships on BenQ's Ergo Arm, which adjusts for height, tilt, swivel and pivot. Owners praise how flexible it is. Pivot means portrait orientation is available, which some people use for long documents or code.

Motion4/10

The refresh rate is 60 Hz, and owners list it as a complaint. For office work and general desktop use this is unlikely to matter much. For fast games, or for anyone used to a higher refresh rate, the 60 Hz ceiling will stand out. The 5 ms GtG response time does not change that ceiling.

Build and setup5/10

Owners report two negatives here. One is a plastic build. The other is difficulty with setup. Given that the monitor has an arm, a hub and a KVM, it is worth setting aside time to get it positioned and connected.

Who it suits

The RD320UA suits someone who wants a large 4K IPS screen with strong docking features and a stand that moves in every direction. The 90W USB-C, the KVM and the 10 Gbps USB-C ports back that up. The 60 Hz panel and the weak HDR reports point away from gaming and media-focused use.
