Most drivers have registry settings that don?t come with a user interface for you to use. These entries are meant for oems to change defaults in reference drivers, for internal trouble shooting, future functionality not yet implemented or settings removed to get Microsoft?s approval. This is not acceptable to your typical computer geek.
How would you like to be able to just edit a few text files or edit the registry and have a new display properties page with a gui for all the cool settings you have discovered? How about a control panel? Or integrated with Desktop Manager? Or as a standalone program running from the taskbar? You can do all 4 of them at the same time with Registry Tweak.
