Screen brightness keys not working on Samsung Ativ Book 9

Just found out that my keys for brightness were not working but the volume works just fine. My OS is Windows 8.1. Help please?

Try the steps here to adjust screen brightness and see if they work for you:

If the steps to adjust brightness do not work, then install the latest version of your graphics drivers to enable adjusting brightness. If they DO work, then download the latest version of Samsung's utilities.
