Hello Cheese,
Thank you for the review!
To open the OSD menu, press on the jog button once and it should appear.
If you are stuck in power saving mode, you need to tap the jog button UP when the monitor enters power saving mode, indicated by a red flashing light. Up on the jog button is the shortcut key for input selection. Otherwise, you cannot enter the main OSD menu from power saving mode.
