My HP Pavilion TouchSmart 23-f250z All-in-One CTO Desktop PC (ENERGY STAR) - Can't Change Brightness

[JD1265]

After several hours of being away from my AIO, the display goes dim and I am unable to change it unless I reboot. I think when I first purchase it, it had Windows 8 or 8.1. I upgraded it to Windows 10 - 64 Bit. 

The display driver is Generic PNP Monitor. When I open the properties for the driver it says:

Location: on AMD Radeon HD 7660D
