The HP Pavilion Modelnr. 500-115ed / D7F07EA#ABH with the AMD Radeon HD 8470 screen adapter. has been connected with a HDMI cable to a 22 inch monitor (LG22EN43).
After the upgrade to Windows 8.1 64 bit (from the Windows 8 64 bit) OS only 20 inch of the display is beeing used.
Screen resolution: 1920 x 1080. (With 1680 x 1050 it displays on 22 inch again)
As directed by the HP helpdesk I have installed the latest display driver from the HP webpage.
Also the BIOS has been updated but both actions did not solve the problem.
This question was solved. View Solution.

After instaling the AMD Catalyst software I could obtain access to the Catalyst Control Center. Here it was possible to adjust the Underscan.
Now we have 1920 x 1080 on a 22 inch monitor.
