The product, explained
About the LG Monitor U4 27U411B-B 27-inch IPS Full HD 144Hz Monitor
LG 27U411B-B.AEK is listed in the computer monitors category. The recorded specifications include display diagonal: 68.6 cm (27"); display resolution: 1920 x 1080 pixels; panel type: Fast IPS; maximum refresh rate: 144 Hz. This entry covers manufacturer code 27U411B-B.AEK. Specifications relate to this exact source record; other editions or packages may differ.
The 68.6 cm (27") display is specified at 1920 x 1080 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.
