The product, explained
About the HP OMEN by HP 31.5 inch UHD 144Hz Smart Gaming Monitor - OMEN 32x
HP 99Z68E9 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 99Z68E9. 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.
