Our take on the BenQ MOBIUZ EX321UX 31.5" 4K UHD 144Hz Mini LED Gaming Monitor

The BenQ MOBIUZ EX321UX is a 31.5-inch 4K gaming monitor built on a 1152-zone Mini LED backlight. It pairs a 144Hz refresh rate and 1ms response with VESA DisplayHDR 1000, so bright HDR highlights and deep blacks sit alongside fast, clear motion. Color coverage reaches 99% Adobe RGB and 99% DCI-P3, which puts it ahead of most 4K gaming monitors that stop at sRGB or a single wide-gamut mode. Connectivity is unusually complete for a gaming panel: HDMI 2.1, DisplayPort 2.1, USB-C with 65W power delivery and a built-in KVM. It suits gamers who also do color-critical work; pure esports players may prefer a smaller, faster 1080p or 1440p panel.

Questions and answers

Is the EX321UX good for both gaming and creative work?
Yes. The 144Hz panel and 1ms response cover fast games, while 99% Adobe RGB and 99% DCI-P3 coverage suit photo and video editing. One monitor can serve both without a second display.
How does Mini LED compare with OLED here?
Mini LED with 1152 zones reaches high brightness for HDR highlights and avoids OLED burn-in risk. OLED still wins on per-pixel contrast, so dark scenes can show slight halos around bright objects on the BenQ.
Can I run a PS5 or Xbox Series X at 4K 120Hz?
Yes. HDMI 2.1 supports 4K at 120Hz from current consoles. The 144Hz ceiling is reached over DisplayPort from a PC.
What does the USB-C port and KVM do for me?
USB-C carries video and up to 65W of power to a laptop over one cable. The KVM lets one keyboard and mouse control two connected computers, switching between them.
Do I need a powerful graphics card for 4K 144Hz?
Yes. Driving 4K at high frame rates takes a high-end GPU. Weaker cards will run 4K at lower refresh or need upscaling to keep frame rates up.
What is HDRi?
HDRi is BenQ's mode that adjusts contrast and clarity based on ambient light and content. It is a tuning feature on top of standard HDR10, not a separate HDR format.
Where is the BenQ MOBIUZ EX321UX 31.5" 4K UHD 144Hz Mini LED Gaming Monitor cheapest?
At Avendor, for $1,538.99, as of our latest check.
