The useful part.

Key strengths

One Thunderbolt 3 cable carries video, data and up to 85 W of charging, and a Thunderbolt 3 output supports daisy chaining; BenQ says daisy chaining does not work on Apple M1, M2 and M3 Macs, only on Pro, Max and Ultra chips.

Manufacturer source Manufacturer source

BenQ declares 98% P3 coverage (its UK pages give sRGB and Rec.709 as 100% in the specification table but 99% elsewhere), an average Delta E of 2 or less, a factory calibration report and a 2,000:1 native contrast.

Manufacturer source Manufacturer source Manufacturer source

It includes a KVM switch, PIP/PBP, a USB-C and three USB 3.2 downstream ports and the Hotkey Puck G2.

Manufacturer source
The checks that matter.

Before you buy

The panel runs at 60 Hz, so it is built for colour work rather than fast games.

Manufacturer source

The HDMI inputs are version 2.0, and the stand needs about 273 mm of desk depth.

Manufacturer source

BenQ lists a 230 W maximum power figure and does not state whether the 9.15 kg net weight includes the stand.
