Which BIOS version is installed?

 

Have you tried the AMD graphics software softpaq from HP?

 

Try the Windows 8.1 version in compatibility mode. Right click the softpaq and click on troubleshoot compatibility.

The following article at the How-to Gee has some info on driver installation.

While connected to the internet go into the device manager.

 

Right click on the display adapter and select update driver software.

The search may take a while, but wait to see if Windows 10 finds an updated driver.

 

An updated driver should resolve the brightness control key issue.

I tried your method It says The best driver software for your device is already installed

 

I Used this tool 

http://www.techspot.com/drivers/driver/file/information/16748/

and I cleaned up all display drivers.

windows searched in updates for drivers and updated all video drivers.

now brightness control key is working

but when i checked dedicated video memory it says 128 MB.

but my dedicated video memory in 1024 MB.

It has been less than a week since the release of Windows 10.

 

I think you are going to have to excercise a little patience and wait for AMD, HP and Microsoft to release updated drivers for special case like switchable graphics. Even AMD has not release anything new for this yet. Eventually one will be released and get up the pipeline to Windows update.

Guys, you dont need to updater your driver or anything. Whenever you update a display driver your generic monitor would be disabled, only think you need to do is enable it by going to > Device Manager > Monitors > Generic Pnp Monitor > Enable. As your monitor is off the Function keys would not work, after enabling it, the keys will work as normal.

 

Check the image.
