BenQ - PD3225U vs HP - Z27k G3 4K USB-C

The PD3225U edges ahead on the Mars Score (63.6 vs 59), but the 4.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the PD3225U if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are screen size.

Pick the Z27k G3 4K USB-C if you care most about usb-c power delivery. Its strongest claims are usb-c power delivery.

Both ship with comparable refresh rate, response time (gtg), peak brightness, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
