The option would be selecting the respective profile through a right click on the desktop and launch it from the profile menu shown there. Basically right click> Graphics options > Profiles > Display Profiles > "Your profile"
For more information on Display profiles option you can check this article:
Thanks for your response. Yes, I know that method. But, actually, that wasn't my question:
How can I switch between them using a hotkey ... or a script ... or some other command?
Are you saying there is NO WAY to switch, otherwise?
Since the methods I listed are commonly used for this kind of thing, can my request be passed to the driver support team for their assessment?
(BTW: other Internet sources list a command line entry of the form <path>\igfxcfg.exe\SchemeName:<profile name> for controllers a couple of years back. Mine is a new HD Graphics 3000.)
In the current user interface the option would be just through the method I mentioned, however let me confirm if these capabilities you mentioned would be still applicable.
