The product, explained
About the Acer Nitro XZ403CKR - 39.7" Curved Wide Ultra HD (5120x2160), 21:9, DFR 360Hz/180Hz, 1ms/0.5ms (GTG, Min.), ZeroFrame, HDR400, FreeSync Prem
Acer UM.TX0EE.002 is listed in the computer monitors category. The recorded specifications include display diagonal: 100.8 cm (39.7"); display resolution: 5120 x 2160 pixels; panel type: VA; maximum refresh rate: 360 Hz. This entry covers manufacturer code UM.TX0EE.002. Specifications relate to this exact source record; other editions or packages may differ.
The 100.8 cm (39.7") display is specified at 5120 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 360 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.
