About the Samsung C27HG70QQN
Samsung C27HG70QQN is listed in the computer monitors category. The recorded specifications include display diagonal: 68.6 cm (27"); display resolution: 2560 x 1440 pixels; maximum refresh rate: 144 Hz. This entry covers manufacturer code C27HG70QQN. 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 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.
