The OSD on offer from the GB2770QSU is in-keeping with what we have seen with previous iiyama displays. All the settings are accessible from 10 tabs – Picture Adjust, Input Select, Audio Settings, Store User Setting, Color Setting, Image Adjust, Language, Setup Menu, Display Information, and Reset:
It's not the best-looking UI in the world but I have to say, it gets the job done. It's not as feature-rich as some competitors, certainly in terms of gaming-oriented features like on-screen crosshair or FPS overlay – which are missing here – but there's plenty of control over other key areas. I'm actually impressed with the overdrive settings too, as iiyama offers five different levels of overdrive (not including ‘off'), when many other monitors are limited to just three different overdrive presets. Being able to save custom profiles is another good addition.
We should also point out that iiyama doesn't currently offer a Windows-based app to adjust different settings directly from your PC, which is something we usually appreciate, but again, given the price-point we can understand the decision.
