BenQ MOBIUZ EX3210U vs Sony INZONE M9 II
The Sony INZONE M9 II is 10 pixels per degree sharper at a desk distance — 69 against 59, and that is the line between sharp and retina-class. Every other published specification for both is in the table, with the rows where they differ tinted.

Sixteen dimming zones is not many, and BenQ never pretended otherwise — what they buy is enough highlight headroom to clear DisplayHDR 600 on a 4K 144 Hz panel that covers 98% of Display P3.
Best for: A living-room-style desk running a PC and two consoles off one screen

Sony built this one around the PlayStation as much as the PC: both HDMI ports are 2.1, the monitor recognises a PS5 and switches picture modes with it, and the case is styled to sit beside one.
Best for: Sharing one 4K screen between a console and a gaming PC

BenQ MOBIUZ EX3210U: what it gives up
- Sixteen dimming zones across 8.3 million pixels means visible haloing around bright objects on dark backgrounds
- 1000:1 native contrast is ordinary IPS, so black is dark grey whenever local dimming cannot help
- No USB-C input at all, which by now is unusual on a monitor this expensive
- 144 Hz is the low end for a 2022 flagship — 4K panels now reach 240 Hz
- No KVM to go with the four-port hub, so the peripherals stay tied to whichever PC holds the USB-B cable
Sony INZONE M9 II: what it gives up
- 1,000:1 static contrast means the dimming zones are doing all the work; on mixed content you can see them
- No USB-C, so a laptop needs its own charger and an HDMI or DisplayPort cable
- No KVM, despite being explicitly sold as a two-machine monitor
- 160 Hz is well short of what the 1440p OLEDs at this price now run
