Gives you full control over attached displays, allowing the usage of all available resolutions and bit depths
This is done by ignoring the operating system setting of hiding potentially unsafe resolutions.
Display Maestro is the ideal tool for running legacy games which require 256-color mode and do not automatically switch the screen depth for you.
The Mac OS X 10.5 Leopard OS removed the ability to set 256 color mode manually using the built-in preferences pane, but the feature is now available here again in Display Maestro!
Display Maestro is a small application which can be configured to launch during login, and sits quietly in the menu bar. Upon exit, it will also automatically revert your display back to the resolution chosen before it was launched.
