Brightness uniformity is merely so-so, with problem areas along both edges apart from the top left-hand corner. Have it your way! Choose one of the predefined gaming modes (including FPS and strategy) or set and memorize your own settings.

Next along are the Eco Modes. These are just numbered 1, 2 and 3, rather than being usage-specific presets. The iiyama G-Master GB3461WQSU-B1 is a bit of an oddity. It's almost unique in offering the 34in ultrawide 21:9 format without being curved. We can't say we really missed it during testing, although we do like the subtle extra immersion a curve provides. Although performance isn't perfect, with colour and brightness uniformity being under par, otherwise this is a good-quality panel capable of high colour accuracy once calibrated, and still good if not.

Drivers/ Firmware / Software

Of course, this is a gaming-focused display so we had to fire up our usual selection of games including CS:GO, Rainbow 6 Siege and League of Legends, but added Shadow Warrior 2 for HDR support. We enabled the FPS Gaming Mode preset for the first two games, and Strategy for LoL. We also enabled FreeSync since it isn't turned on by default. We performed the quality tests on the iiyama G-Master GB3461WQSU-B1 at its native 3,440 x 1,440 resolution in the default mode, after resetting the OSD, which sets the refresh to 144Hz over a DIsplayPort connection. Our test system was equipped with an AMD Radeon Vega Frontier Edition graphics card, which supports FreeSync, so we enabled that for games testing. This monitor has amazing specs for the price. You honestly can't beat it. The OSD is a bit annoying to use but it's kind of a set it and forget it deal. Honestly, this is the ultimate 400 monitor to beat. All the gamma modes are 0.1 higher than their numbering would suggest. But at least they're consistent. The colour accuracy, expressed as a Delta E ratio, with a result under 3 being fine for normal use, and under 2 being great for colour-accurate design work.

We pay careful attention to any artefacts, ghosting or motion blur, and enable any gaming-specific features, such as adaptive-sync settings like G-Sync or FreeSync, using a compatible graphics card in our test PC. Finally, the Setup Menu lets you configure the way the video input is displayed, with 17, 19, 19.5, 21.5, 23 and 24in options. The first two are 5:4 aspect and others 16:9. With an HDMI input, you can choose whether to use the full or limited RGB range. You can enable or disable FreeSync and HDR, whether the opening logo is displayed as well as the power LED. Memory recall is actually the factory reset option. The percentage of the approximate area, taken by the active part of the screen, to the total front area.Hardly ideal, and difficult to verify seeing as the bug rarely appears, but it is encouraging to learn that iiyama's technical team is working to resolve the matter. In the meantime, let's turn our attention to the benchmarks.

If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen. With IPS panel, 144Hz refresh rate, 1ms MPRT and the 3440x1440 resolution, the monitor allows hardcore gamers to unleash their gaming potential and enjoy superb image quality.
