Display Maestro 5.3 – Optimize resolution and bit depth for attached displays

Display Maestro 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.
 
Newer versions of macOS have removed the essential ability to select specific resolutions, or even see which alternative ones are available! With Display Maestro, Pro users can now regain access to the full spectrum of available resolutions and also advanced metrics.
 
Display Maestro is a small application which can be configured to launch during login, and sits quietly in the menu bar.
