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.

Exactly the "one-trick-pony" I needed :D

Allows me to quickly toggle the 'faux-Retina' HiDPI resolution on my non-Retina MBP for testing hi-res artwork.

It's a pain to use the System Preferences Display pane, which (sensibly) jumps front and center, covering whatever you're looking at.
With the user-defined key combination, I can avoid the extra steps. Well worth it if you have to switch back and forth repeatedly.

I will heartily second the suggestion that it could offer a checkbox to enable the HiDPI option on non-Retina screens. This way the user avoids the hassle of a) hunting down the appropriate terminal command or b) having to install Xcode just to set a checkbox once in the Quartz Debug utility.

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.

So simple, yet so helpful!

I love this app!

I have a 13" Retina - I love the mobility of it - and I do a lot of work in Photoshop and Lightroom and I found the default 1280x800 HiDPi works well while browsing the Internet, but not while editing photos!

My normal method of having to go into the system settings every two minutes to change the resolution was a pain!

THANK YOU FOR THIS! It solves all of those problems!
