The PG32UQX uses a fairly unique way of navigating the OSD – a dial. The dial itself also houses a clickable button, and it is also flanked by another button on either side, and honestly it works very well – I'd argue it's better than a joystick as it's easier to move through a long list of settings.
When you first click the dial button, an initial pop-up menu appears. This is where you can use the buttons either side of the main dial, as they work as shortcuts to access a variety of functions – and yes, they can be remapped. If you then choose to access the main menu, the left button functions as ‘back', while the right button will exit the OSD.
From there, you simply use the dial to navigate to your chosen tab, and click in on the dial button to access the settings. It's really very simple and makes quick adjustments of brightness levels, for instance, very easy.
As for the settings themselves, you have all the usual fare. There's overdrive options, a selection of ROG GameVisual presets, FALD control, RGB options and more. The GamePlus settings also offer up crosshairs, an on-screen FPS counter and a timer. I really can't complain about any missing features and everything is laid out in a way that makes sense. Good job, ASUS.
