AOC has stuck with its more traditional OSD system for the Q24G2A – it's one we've seen many times of the years, with the likes of the AG251FZ2E and U28G2XU. The settings are split into seven main tabs:
AS OSD systems go, this one is fine – everything is sensibly laid out and it has all the key features I'd expect. It's pretty ugly though, and I have to say I really dislike using back and forward buttons to get around an OSD – I've lost count of the amount of times I accidentally turned this screen off when I was trying to press enter… Maybe I've become spoiled by OSD joysticks but I'd have loved to see one here.
AOC does has its iMenu software too though, which gives you control over most of the key monitor functionality. It's not an overly sophisticated piece of software but if you want to quickly change brightness or adjust overdrive without fiddling with the physical buttons, it works.
