How to adjust XBMC to fit your TV screen

• Video calibration workaround that only works until you reboot: open menu “system” > “settings” > “system” > “video output” > “video calibration” and then adjusting the  image manually to fit the screen
• Skin size workaround: open menu “system” > “settings” > “appearance” > “skin” and edit the “zoom” value to “-6%”
• Reboot and enjoy your settings....if you need to adjust the percentage up or down just do it till it looks fitting and then reboot and it will stay there permanently.
