iiyama GCB3480WQSU Evaluation (180Hz Ultrawide)

Share it

The rising trend of ultrawide gaming monitors is becoming more widespread, and fortunately, they are also becoming increasingly budget-friendly. The iiyama GB3480WQSU features a standard 3440×1440 VA panel with 1500R curvature, boasting a refresh rate of up to 180Hz through overclocking, along with adaptive sync technology and a claimed 4000:1 contrast ratio, all available for £340. We conducted a comprehensive series of tests to determine whether it justifies a purchase.

The last time I assessed an iiyama monitor, particularly an ultrawide one, was quite a while ago – back when the GB3466WQSU, a fantastic value offering, was on the market a few years back. The GCB3480WQSU appears to be a significant upgrade on paper, promising better contrast and, significantly for gamers, a higher refresh rate and quicker response times. Cheaper VA panels can sometimes struggle with issues like dark-level smearing, so let’s see how this display performs.
