We've reviewed plenty of ultrawide monitors over the years, but none quite like the AOC Agon AG405UXC. That's because this screen offers a 3440×1440 resolution over a 40in panel size, making it a good chunk bigger than the typical 34in ultrawides we are used to seeing. It's still sporting a 21:9 aspect ratio – so isn't on the same level as a 32:9 super-ultrawide – but at £530, you get a lot of screen for the money. Let's find out if it's any good.

Alongside its headline 40in screen size and 3440×1440 resolution, the AOC Agon AG405UXC is sporting a flat IPS panel with a claimed 1200:1 contrast ratio. It offers a 144Hz refresh rate, and a claimed 4ms GtG response time, alongside DisplayHDR 400 certification. Today we put it through its paces and find out what the AG405UXC has to offer at the £530 asking price.
