AOC's OSD system is broken down into eight main tabs:
As for the OSD itself, I admit I was very surprised to see AOC using its older and now very dated menu system for the AG276UZD. After all, this monitor only launched in May, and we've seen other screen recently – like the U27G4R – that have been updated with a much more modern OSD system. I did ask AOC about this and they told me the next generation of OLED screens would be updated, but there were no plans to push a firmware update for the AG276. It's at least a functional OSD complete with the features we'd expect to see, I just think it looks very clunky and dated in 2025.
AOC does also offer its GMenu software though, allowing control over the same settings but directly from your PC. It can also be used to update the monitor's firmware, which is always a good inclusion.
