The product, explained
About the DELL S3221QS
DELL DELL-S3221QS is listed in the computer monitors category. The recorded specifications include display diagonal: 80 cm (31.5"); display resolution: 3840 x 2160 pixels; panel type: VA; maximum refresh rate: 60 Hz. This entry covers manufacturer code DELL-S3221QS. Specifications relate to this exact source record; other editions or packages may differ.
The 80 cm (31.5") 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.

What does the COR Score mean?
One consistent scale makes different publishers’ ratings easier to compare. The original review still tells you why a critic reached that verdict.
