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.

Does exactly what it's advertised to do. Very responsive developer, too. In my opinion this is an essential Mac app as it brings back features that Apple has taken away over the years and puts them back to use. Can't argue there. Absolutely recommended.

Kyle Fox

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.

To have the big resolution on small screen is the best way to upgrade your screen size without change the screen itself.. Thank you very much for the innovation!! This is COOLL!!


This app does what it says. It allows me to configure my retina display 15 inch Macbook Pro to the same rez as the 30 Inch Cinema Display. That way I can use them as the same area in size. But what I really like is. When I mirror the displays, while I am on the go with just the rMBP, the items and apps that place items on the desktop all stay in place. Such a time saver and hassle reducer! Thank you for making Display Maestro!

It even works with multiple display devices. I'm impressed. The details about each resolution is a nice touch, too. I'd recommend this for anyone with multiple displays, and I know there's a lot of that out there these days.

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.

Great to present in diferent environments outside my home and office Great Help

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

Nikki Staley

My Macbook Pro was forcing me to use my LG 27" 4k USB-C displays at a lower resolution and 30hz as the only resolution available (the "Best for Display" setting was the only choice). Display Maestro allows me to use all available resolutions so I can match visual size arrow multiple displays simultaneously, with higher refresh rates.

great little app should have been available in mac Os
