You mean like in:

and:

Keep in mind that while this registry hack has been shown to work with a number of netbooks from different manufacturers, it might not work with all netbooks, and modifying your registry is always something you do at your own risk. It's always a good idea to backup your registry before making any changes by going to the file menu and exporting it.

It depends on the video driver:
