The product, explained
About the HP OMEN by HP 27 inch QHD 240Hz Gaming Monitor - OMEN 27qs
HP 780J4E9#ABB is listed in the computer monitors category. The recorded specifications include display diagonal: 68.6 cm (27"); display resolution: 2560 x 1440 pixels; panel type: IPS; maximum refresh rate: 240 Hz. This entry covers manufacturer code 780J4E9#ABB. Specifications relate to this exact source record; other editions or packages may differ.
The 68.6 cm (27") display is specified at 2560 x 1440 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 240 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.
