Displays Unlocked

Display Maestro gives you full control over attached displays, allowing the use of all available resolutions and bit depths. Latest versions of macOS strip out the useful ability to set specific resolutions and presents a more user-friendly approach.

Experienced users, especially graphic designers and presenters, demand more precise control of their devices. Access exactly the resolution you need with Display Maestro's traditional Mac-like menu.

Access the full list of resolutions and bit-depths supported by the graphics card and attached display. Note that some graphics cards may limit the display's options.
Older games and apps sometimes require the use of precise resolutions, and can no longer set these automatically due to changes in macOS. Display Maestro lets you pick exactly the configuration you need.
Display Maestro implements functionality that will detect if an unsafe resolution was chosen and will automatically revert to the last known safe resolution if confirmation is not given.

This is perfect! I have multiple monitors set up and this is just what I needed. So simple and useful. Worth every penny I paid for it. I probably would have paid thrice that if you'd asked me to.

Colton Rau

Without a doubt a great piece of software that works like a charm :)

Stephen Janse van Rensburg

GREAT app, and wonderful developer to boot. Answered all my questions thoroughly, quickly and kindly. I have a feeling I'll be owning several more Koingo apps here within the next few months. It's just a matter of time now.

Devon Johnson

Not a lot to say! I don't change my display resolution often, but when I want or need to, the mechanism is right up there in my menu bar.

Paul Schumann

Great for playing old games! I'm a huge legacy gamer so this app is perfect. There's nothing worse than trying to play an old game in the wrong resolution. It feels like a default Mac function too, the way it just sits up there in the top bar. Love it.

Kaylee Harrington

It works fine! I´m satisfied.

Felix Jean-Pierre Felixine

Excellent software, helps use the full scale of my Retina display

Olivier Brunet

It is a very useful item , It adjust to the available proyector easy

Jorge A Diaz

I'm usually wary about third-party apps that screw around with your settings, but this one is good. Everything reverts back to normal once you quit the app so you don't have to worry about permanently botching something up. A great addition to an already great operating system.

Max Rosenberg

Saved my (production) life, when Apple took away resolution options!
