Our take on the BenQ EX321UZ computer monitor 80 cm (31.5") 3840 x 2160 pixels 4K Ultra HD OLED

The BenQ MOBIUZ EX321UZ is a 31.5-inch 4K QD-OLED gaming monitor with a 240 Hz refresh rate and a 0.03 ms response time. Its quantum-dot OLED panel delivers near-infinite contrast, 99% DCI-P3 coverage and up to 1000 nits peak brightness in HDR, plus 90 W USB-C power delivery for a single-cable laptop setup. It suits gamers who want big-screen 4K OLED speed and creators who need wide color, though its 300-nit full-screen brightness and OLED burn-in risk are the main trade-offs against Mini-LED rivals.

Questions and answers

Is the EX321UZ good for PS5 and Xbox Series X?
It handles 4K at high refresh over its inputs, so consoles look sharp, but check the port list for HDMI 2.1 before relying on 120 Hz console modes. The OLED panel makes HDR games look excellent in a dim room.
How bright is it in a bright room?
Typical full-screen brightness is 300 nits, with 1000 nits only in small HDR highlights. It looks best in controlled lighting; a sunny room will wash out full-white scenes compared with a bright Mini-LED monitor.
Is 240 Hz worth it at 4K?
Only if your GPU can push high frame rates at 4K. Otherwise the 240 Hz panel is wasted, and a 4K 144 Hz or 1440p OLED may suit you better.
Can I connect a laptop with one cable?
Yes. USB-C delivers up to 90 W of power plus video, so many laptops run and charge from a single cable. Confirm your laptop accepts 90 W over USB-C.
Should I worry about OLED burn-in?
Static taskbars and desktop icons can leave marks over long sessions. BenQ adds a graphene film for durability, but vary content and use screen-off timers if you work all day on static apps.
What is in the box?
Expect the monitor, stand, power cable and video cable. Check the listing for the exact cable type and whether a USB-C cable is included.
