ScreenSizer is the simplest way to view a variety of screen and monitor sizes easily. Just double-click on it and it will
immediately display the outlines of all the monitors and displays up to and including your own. From the old MacPlus all the way up
the modern Cinema Displays, ScreenSizer has been pre-configured to display them all.
The Preferences window configures everything... you can delete any of the currently configured screens, or create new ones and when you click on any of the screens in the list, you can edit any of the settings. The 'Screens' menu will contain all the screens that are configured and you can open/close them from the menu (and associated hot keys). The screens you leave open when quitting will be opened when you run the application again.
Another great thing about ScreenSizer is that it's free... however, if you do find it useful, I would appreciate it if you bought me a beer! In that sense, ScreenSizer is "BeerWare"... just click on the beer icon to the right to buy me a beer... Cheers!!
