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/ DisplayResolutionEnabled -bool YES.
3. Log out and log in again.

Done. HiDPI is activated and ResolutionTab will work properly.

What's New in Version 1.1

- 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.

Worthless for external monitors.

Hilariously, this works beyond rediculous with the built in MacBook Retina screen. You can go up to a whooping illegible 2880x1800. However, I bought this for my EXTERNAL monitor, an ASUS PB278Q with 2560x1440, and guess what, this junkware won’t display over 1600x900 on that monitor. What’s really funny as well is Apple’s Retina MacBook’s are truly horrible with external displays. They did away with resolution settings altogether, and instead give you this obscenely stupid “feels like” setting which gives you ZERO control over the resolution of external monitors.
The old MacBook Pro (pre-Retina) worked perfectly with external monitors, displaying their true dimensions, but I’m sad to say the MacBook Retina as well as this software both conspire to make external monitors worthless. Thanks guys.

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.
