Netbook with ATI graphics: Brightness settings doesn't work

I have a hp dv6-6000 series Windows 7 64-bit laptop with an Intel HD3000 and an ATI HD6700M. After a factory reset I upgrade drivers and I got the problem:

If I want to be able change between graphic cards I can't set the brightness if I'm using the ATI one, and if I want to control the brightness I have to reset the drivers but I can choose the graphic card.

I tried uninstalling Monitor (I don't have the checkbox with the uninstall driver option) and "search hardware changes" and then Win+X, but doesn't work.

Edit: I don't have any program like TeamViewer.

Please use Shift more generously when typing "I" :) Are there any unrecognized devices in Device Manager? – gronostaj – 2014-09-13T18:32:17.443

No, laptop detects both graphic cards and monitor (as Generic PnP Monitor). – Name – 2014-09-13T18:52:31.397

Do you by any chance have TeamViewer or similar software installed? If so, have you made sure that TeamViewer's mirror driver isn't installed? – Vinayak – 2014-09-13T19:13:59.920
