Overview
An AI noise-cancelling microphone is not something you expect on a gaming monitor, and it says something about how BenQ thinks about the EX3210U: this is a 31.5-inch 4K panel meant to handle Discord and streaming as well as games. The audio story continues with a 2.1 treVolo system and a 5 W subwoofer. The panel is AHVA IPS at 144 Hz with DisplayHDR 600 behind a genuine 600 cd/m2 peak and 98% DCI-P3, plus two HDMI 2.1 ports and four USB-A downstream. The 2021 vintage shows in contrast - 1000:1 with no dimming zones listed - and in a stand that offers 100 mm of height and +/-15 degree swivel.

HDR & Brightness Reality
DisplayHDR 600 with a 600 cd/m2 peak is the tier where LCD HDR starts to be worth switching on, and this panel has the brightness to make highlights genuinely brighten. The limit is the familiar one: 1000:1 native contrast with no dimming zones published, so the dark half of an HDR image stays grey while the bright half works. In a normally lit room that reads well; in a blacked-out room, the black floor gives it away. The sheet also omits typical brightness, listing only the peak.

Frequently Asked Questions
01 Why does a monitor have a microphone? +
BenQ built the EX3210U around communication as well as gaming - the AI noise-cancelling mic means you can take Discord calls or stream without a headset, which pairs with the 2.1 treVolo speakers. It is rare, and genuinely convenient.
02 Is DisplayHDR 600 real on this panel? +
The brightness side is - it peaks at 600 cd/m2, so highlights genuinely brighten. Contrast is the catch at 1000:1 with no dimming zones listed, so dark scenes stay grey. Better HDR than an HDR400 panel, well short of OLED.
03 Is a 2021 model still worth buying? +
The panel specs hold up - 4K, 144 Hz, DisplayHDR 600 and two HDMI 2.1 ports remain relevant. What has moved on is contrast: OLED panels at this size now deliver blacks this cannot match, and often at similar prices.
04 How many USB ports does it have? +
Four USB-A downstream from a USB-B upstream, which is more than most monitors give you. There is no USB-C, so no single-cable laptop docking.
05 Why is there no typical brightness figure? +
The sheet lists only the 600 cd/m2 peak. For an LCD, typical brightness is usually close to peak - unlike OLED - so it is less of a gap than it would be on a self-emissive panel.
