Key strengths
The OLED panel pairs a 240 Hz refresh rate and 0.03 ms GtG claim with a listed 1,500,000:1 native contrast.
USB-C carries DisplayPort Alt Mode video and data alongside HDMI 2.1 and DisplayPort 1.4 inputs, and 2 × 2 W speakers are built in.
Before you buy
The USB-C port’s power delivery is listed at 15 W, and BenQ’s connectivity table lists no USB-A ports.
Typical brightness is listed at 200 nits and the screen has a glossy (glare) finish, so bright rooms may be challenging.
Every specification. With its source.
