Make sense of the details

Choosing the iiyama XCB4994DQSU-B1

The 124.5 cm (49") display is specified at 5120 x 1440 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 120 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.

Before choosing this monitor

  • Measure desk depth, viewing distance and arm clearance.
  • Check computer output, monitor input, cable and dock as one chain.
  • Choose a stand or arm with the adjustment you actually need.
  • Use independent tests for brightness, uniformity, text and motion.
