Description of TMonSett :
TMonSett and THiddenMonSett are two components used to manage the display settings (video modes, wallPaper, start screensaver, turn off/on the monitor) from your Delphi application. They both do the same things, the only difference betwen them is that TMonSett has it's own integrated user interaface to display the current display settings, and buttons through which the user can change these settings. THiddenMonSett is an invisible component, so you can define your own user interface.
