SwitchResX is the most advanced tool for Apple computers to take control of any screen connected to the Mac. No matter whether a MacBook Screen, an external monitor, a Retina display, a TV set or a beamer: SwitchResX can handle them all - if you want, straight from the menubar, a contextual menu or both. It's that easy!

Preference Pane And More
When installed, SwitchResX sits in the Preference Panes and can be activated like any other of those helpers. SwitchResX pops open in a separate window for easy access of its' vast amount of functions, that outrun Apples inbuilt Monitor preference pane easily.

Ultimate Control
With SwitchResX you can keep control of your screen resolution and the way, every single app displays its content on your screen - or screens! Because SwitchResX can of course handle more than one screen totally individually, it gives you all the freedom and flexibility you need at any time.

Drill Down Into Details
On top, SwitchResX includes a huge amount of additional functions, like
Saving desktop layouts to get everything back into position right the moment, you jump back to a certain resolutionDisable or activate screens on demand, for example to use a Macbook in clamshell modeLink screens to specific events like Key shortcuts, Applescript, Application launches and moreCreate and enable new custom resolutions to adapt to any available screen, including screens inbuilt into carsRename resolutions to regular and useful terms like Gaming, Documents, Graphics, Presentation, TV etc.Arrange desktop items on a much finer grid than Apple' standard settingsKeep a record of any change in screen setting automatically
SwitchResX 4.11.1
Better support for M1 Macs:
Can now again set grey levels, display brightnessCan now create custom *scaled* resolutions (for the internal display on MacBooks: only on macOS 11.3 and above), and only resolutions that are smaller than the native resolutionCan also set the base of scaling (which solves an issue on Dell UPK2715K monitors with M1 Macs under macOS 11.2)Also correctly manages more than one display on M1 Macs (on v.4.11, all graphic cards were shown, even if no display was plugged, and even the TouchBar of a MacBookPro could be visible!). However this removed the ability to disable a display on the DTK. Who cares, the DTK will die in some weeks...The Display Product & Vendor IDs are now correctly reported again; as well as the Display Name (which isn't always visible after a wake from sleep)Solves some memory leaks in the SwitchresX Daemon, especially on M1 MacsTries to report the correct timing parameters for all resolutions on M1 Macs - at least for the current resolutionCorrects an issue where the Contextual Menu was not installed with 4.11 on macOS 10.14 and below (macOS 11 doesn't support it any more anyway)Corrects an issue where the current display mode wouldn't be shown as selected in a specific case (in details - when it ID was 0)Correctly sets the gray levels again if selected from the MenuCorrectly matches two monitors from same vendor but with different product ID, as well as identical monitors with different serial numbersSolves an issue when opening the control panel would be unresponsive for a minuteSolves an issue on macOS 10.15.7 with SIP enabled, where installing the helper tool wouldn't be possible after first runSolves an issue where a Display Set saving only display positions wouldn't remember its setting when the display would be removedUsing SwitchResX Daemon with AppleScript, the refresh rate of a mode is now reported as a float, and billion of colours are also reported correctlyAdded the aspect ratio column in custom resolutions list
