The capability to invert the display is a feature of the IntelĀ® Extreme Graphics that ships with i845 chipset PC’s. Rotation is enabled by default and is activated by the default key combination down, hence why the display may rotate when playing certain games with the keyboard. If you are experiencing this problem, you can disable the rotation feature. To disable rotation, right click the Intel Extreme Graphics icon on the taskbar, select Graphics Options, then Graphics Properties. Click on the rotation tab and remove the tick from the enable rotation box. Alternatively it can be accessed from Display Properties – Settings – Advanced – Intel Extreme Graphics – Graphics Properties.
