Windows 7: Cant switch graphic cards on HP pavilion DV7 6050ec

Cant switch graphic cards on HP pavilion DV7 6050ec

I just reinstalled my computer with windows 7 64bit and I have HP pavilion dv7 6050ec with two graphic cards : mobility radeon HD 6770M and a generic Intel HD Graphics Family. Since I reinstalled the computer, I no longer have to option to chose what graphic card I want to use. Before this reinstallation I could just right click on the desktop and there was a option that said Switch Graphical units, but now there is nothing like that. And I have the latest drivers for both graphic cards and latest Catalyst Control Center and Direct X installed. And in device manager all drivers are installed correctly. So I have no idea what to do.
Please help

Have you looked in BIOS to disable the onboard video? I don't know where that option came from, I confess that I've never seen it. Otherwise, you could try and disable the onboard video in the device manager.

Interesting. I wasn't aware of AMD Switchable Graphics technology, which compete with nVidia's "Optimus" scheme.

HP Notebook PCs - Switchable Graphics on Notebooks Configured with Intel and ATI GPUs - c03048374 - HP Business Support Center

There are no instructions there on the specifics of what to install, but I guess that you'd need both the AMD Catalyst drivers and the Intel onboard graphics drivers.

Looks like you are right - requires a specific driver version for both drivers and a specific BIOS version (or newer), and then the option is in the ATI Catalyst control center thereafter:
