The product, explained
About the iiyama XCB4994DQSU-B1
iiyama XCB4994DQSU-B1 is listed in the computer monitors category. The recorded specifications include display diagonal: 124.5 cm (49"); display resolution: 5120 x 1440 pixels; panel type: VA; maximum refresh rate: 120 Hz. This entry covers manufacturer code XCB4994DQSU-B1. Specifications relate to this exact source record; other editions or packages may differ.
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.

Which exact version does this page cover?
This page identifies iiyama XCB4994DQSU-B1 using manufacturer code XCB4994DQSU-B1. Check that code, configuration and supplied accessories against the retailer listing. Related-version reviews are labelled separately and do not contribute to this version’s score.

The source specification records display resolution as 5120 x 1440 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 XCB4994DQSU-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.
Does a higher refresh rate make every app better?
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?
It depends on size, desk distance and use. Try it for text and multi-window work, not only video.
