Make sense of the details
The 71.1 cm (28") 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 60 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.
Compare the specification with your intended use and read the original reviews for performance, comfort, reliability and other qualities that a specification sheet cannot establish.
