SwitchResX is a tool designed to manage resolutions of all your monitors.

Features:

• Create custom resolutions for using your Mac as a home theater, and plug it to your HDTV
• Create the custom resolutions needed to correctly use your MacMini in you car
• Add only the resolutions that you need to the menu bar, and give them names that you can recognize quickly.
• Define settings for all your monitors in one set, and give them explicit names ("DVD", "Games")
• Let these settings be applied automatically when an application starts, and set back when the application ends.
• Save icons on your desktop automatically before a resolution change occurs, replace them after the change to an other saved position
• Save positions and size of your windows, remember their position when you plug an external monitor, automatically back to the previous layout when you unplug the monitor
• Rearrange your desktop icons on a grid, with finer precision than the Finder
• SwitchResX can be scripted for resolutions and color depth changes. SwitchResX is even recordable: When it is running, every resolution change is automatically recorded in the script editor…
