The product, explained
About the iiyama X4373UHSU-B1
iiyama X4373UHSU-B1 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: VA; maximum refresh rate: 60 Hz. This entry covers manufacturer code X4373UHSU-B1. 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.

The source specification records display resolution as 3840 x 2160 pixels. This is a specification, not an independent performance measurement. Check the exact model and the original critic reviews for real-world results.
Where can I compare prices for iiyama X4373UHSU-B1?
Use the retailer-offer section on this page for available matched offers. If no offer is shown, we do not currently have a verified price. Confirm model, stock, delivery and the final total at the retailer; coverage does not include every seller.

It can make movement feel smoother, but benefits depend on the computer, connection and the activity.
Can I use a USB-C monitor with any laptop?
Not necessarily. Check the laptop port supports the required display mode and charging level.
Is a curved monitor always more immersive?
