Install driver in compatible mode with windows 7, the ccc and it worked, i set the screen scaling, but the problem now is that every time I switch on my pc all the ccc values are reset and must reconfigure the scaling
Why don't you just do what I see you need to do? It's fine over here if you follow my steps....
I guess you didn't install the windows 8 CP drivers?

There you go. Only problem is you will need to COMPLETLY remove all other drivers. I recommend re do the installation and install only these drivers/.
Guys, installing 11-12_vista64_win7_64_dd_ccc_ocl.exe by right clicking and selecting Troubleshoot Compatability (which set it to Win XP SP3) has solved this for me.
CCC installs and runs fine, I can configure the overscan and my second monitor is finally back to normal.
Are you able to get flash videos to work on youtube or vimeo or anyplace online? I am finding my browser freezes and I can hear audio but see a solid green color where the video should be. This occurs under the desktop and metro version of IE, the latest beta of Firefox and the latest beta of Chrome. I have uninstalled, rebooted computer and reinstalled flash mutliple times as well as the drivers for my Radeon 4890. I believe flash uses hardware acceleration from the graphics card which may or may not get corrected anytime soon.
