The product, explained
About the iiyama TF4339AS-B1AG
iiyama TF4339AS-B1AG is listed in the computer monitors category. The recorded specifications include display diagonal: 108 cm (42.5"); display resolution: 3840 x 2160 pixels; panel type: IPS; maximum refresh rate: 60 Hz. This entry covers manufacturer code TF4339AS-B1AG. Specifications relate to this exact source record; other editions or packages may differ.
The 108 cm (42.5") 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 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.

Not necessarily. Check the laptop port supports the required display mode and charging level.
Is a curved monitor always more immersive?
