ResolutionTab is a menu bar app for fast switching between Standard & HiDPI display modes.
Modern apps and websites should look great on Retina displays, so we have to test them in both standard and ultrahigh resolution modes. But when you configure your display in System Preferences, it takes plenty of time to switch from the standard to the HiDPI mode and vice versa. ResolutionTab is a minimal app living in the menu bar that toggles your Mac between Retina and non-Retina resolutions in one click.
— 15" MacBook Pro Retina is compatible with HiDPI modes by default, so ResolutionTab will work out of the box.
— 11" MacBook Air is not compatible with HiDPI. The screen is too small, so resolution would drop below the minimum required by OS X.
— In all other cases, you have to enable virtual HiDPI modes manually.
Here is how to do this with Administrative privileges:
1. Launch Terminal app located in your /Applications/Utitlities folder.
2. Type sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES.
3. Log out and log in again.
Done. HiDPI is activated and ResolutionTab will work properly.
- Improved menu and Preferences window.
- An option to launch the app at login.
- The full list of display modes in the menu.
- Global keyboard shortcut to quickly switch to the previous display mode.

Does what it says, and well
This is a great lil app for the price. On my 15" Retina it easily allows me to switch from my usual default of the "Looks like 1920 x 1200" in the Apple Pref Pane to the Full 2880x1800 of the retina display- and the full spectrum of display options in between.
The big selling point for me was that it allows quick toggle between these "custom hires modes" that it enables and the default pref-pane based resolution. The other resoltion app, "Display Menu" gives you access to the custom hires modes but forces you back through the standard display prefpane to regain 1920x1200 hidpi mode, which is a pain after about the 4th switch.
Fixes Mojave for external 4k monitor
Useful display scaling for external 4k monitors never shows up in MacOS Mojave for my external displayport monitors plugged into my 15" MacBookPro with 'Retina' display. That would leave me with either microscopic user interface elements, or blurry enlarged user interface except for video with looked great.
ResolutionTab fixed Mojave's display scaling problems for me by providing an appropriate HiDPI scaling for 4k. Now content on the 4k monitor is just as sharp and about the same apparent size as the inboard retina display panel.
THANK YOU!!!!! to the developer!!
Works as advertised
I got this app to test some UI work in HiDPI mode and it seems to work flawlessly. The initial setup should probably display the information on enabling HiDPI mode instead of burying it under “More Information…” in the “HiDPI mode not available” dialog, but maybe I missed that info somewhere else.
I like the fact that in a multi-monitor setup like mine, one monitor can be set to HiDPI mode while the other one isn’t.
Simple, cheap, works great: 5 stars.
With Family Sharing set up, up to six family members can use this app.
