RE: Alienware X51 R2 Keyboard Commands
Check in the Programs and Features list to confirm if you show an application called Alienware On Screen DisplayApplication or OSD. If you do show it, uninstall it and restart the system, then proceed to install the OSD application again. Click here for the OSD application download link. If it does not show on the Programs and Features list, install it and then test the function keys again.
