The product, explained
About the BenQ EX321UX
BenQ 9H.LM7LB.QBE is listed in the computer monitors category. The recorded specifications include display diagonal: 80 cm (31.5"); display resolution: 3840 x 2160 pixels; panel type: IPS; maximum refresh rate: 144 Hz. This entry covers manufacturer code 9H.LM7LB.QBE. Specifications relate to this exact source record; other editions or packages may differ.
The 80 cm (31.5") display is specified at 3840 x 2160 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
The listed maximum refresh rate is 144 Hz. To use it, the source device, cable, resolution and input must all support the intended mode. Refresh rate is separate from response time and input lag.

Review covers BenQ EX321UX. The verified product-data labels bind this public model name to code 9H.LM7LB.QBE, and the original publisher article independently supplies the editorial score. This is not proof that the supplier supplied this review URL, or that the reviewer tested this colour or included accessories.
