The product, explained

About the iiyama GCB2784HSU-B1

iiyama GCB2784HSU-B1 is listed in the computer monitors category. The recorded specifications include display diagonal: 68.6 cm (27"); display resolution: 1920 x 1080 pixels; panel type: VA; maximum refresh rate: 240 Hz. This entry covers manufacturer code GCB2784HSU-B1. Specifications relate to this exact source record; other editions or packages may differ.

The 68.6 cm (27") display is specified at 1920 x 1080 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 240 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.

How we calculate the score →

Independent ratings, converted to the same five-point scale. Each card links to the original review and identifies the available evidence.

No scored critic reviews have been imported for this exact product yet. It remains unrated.

Independent reviews, made comparable

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.

Scale conversion · example

8/ 104.00/ 5

An illustration of conversion, not this product’s rating.

  1. Check the match

    Identify the exact model and the version reviewed. Check the manufacturer code, configuration and supplied accessories.

  2. Compare on one scale

    Convert usable ratings to five points, count each publisher once and give each critic equal weight.

  3. Require three critics

    Show the average to two decimal places after three distinct critics. Otherwise display tbd, keeping individual reviews visible.

Find the best fit by considering the score alongside the critic count, review dates, tested version and the strengths that matter to you. Eligible model-level reviews identify the tested configuration. Reviews of different hardware are shown separately and do not enter this product’s COR Score.

Which exact version does this page cover?

This page identifies iiyama GCB2784HSU-B1 using manufacturer code GCB2784HSU-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.

What is the listed display diagonal for iiyama GCB2784HSU-B1?

The source specification records display diagonal as 68.6 cm (27"). This is a specification, not an independent performance measurement. Check the exact model and the original critic reviews for real-world results.

What is the listed display resolution for iiyama GCB2784HSU-B1?

The source specification records display resolution as 1920 x 1080 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 GCB2784HSU-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.
