Open SwitchResX from the System Settings and add two resolutions. Press Ok Close SwitchResX and save when prompted. One for the native 2388x1688 resolution and one for the 1194x834 halved ‘Retina’ one. You need both in order to be able to use Retina mode.

To do that, I use a custom Terminal program that’s based largely on Jeffrey Osterman’s code posted in this Mac OS X Hints Forums thread.

Here, I have two external displays connected to my laptop (whose internal display is turned off and is not showing).

Select your display in the left pane and click the Custom Resolutions tab. In a Terminal window type: csrutil enableĭone.

In the menu bar, go to Utilities -> Terminal to open a shell, and type:Īfter you’re done playing with SwitchResX, reboot the Mac and Cmd+R again.

Release the keys and let it finish the boot process.

Restart your Mac, holding Cmd+R until you see the Apple logo.

The one thing to remember, is to turn SIP back on, after you’ve finished creating your resolution. Disabling SIPĭon’t ask me why we have to disable a system security feature to tweak our displays, but that’s how it is. Or, like me, if you’re bad with numbers use a resolution scale calculator to be on the safe side and get a list of compatible resolutions for your screen, based on its default resolution. Google you model if you’re not sure what it is. It’s 16:10, in my case, many displays are 16:9. Unless you want to see things distorted on your screen, your new resolution must use the same ratio as your display. But I know Active Horizontal, Active Vertical and Scan rate (the one defined in Hz, the rightmost at the bottom of the screen, not the one in KHz next to it) are the values to keep in mind. I have no idea what all these values mean. In the left pane, select your display and click the Current Resolutions tab. I repeat: you must not use settings over what your display is physically capable of, or things will go wrong, and getting them back in order is no fun if you don’t have a second screen.Īfter installing SwitchResX, go to System Preferences->SwitchResX.

#USING SWITCHRESX INSTALL#

You need to install SwitchResX before you can do anything.

Do not forget to turn it back on after you’ve created your custom resolution(s).

You will need to use the Terminal to deactivate SIP - what the heck is SIP?.

So, take your time and if you don’t feel confident enough to do it by yourself, don’t do it by yourself.

Playing with custom display resolution is not complex, but it’s easy to screw up and turn your monitor to full black without an easy way out.

I will show how to check these in a moment. Also, you can’t use a screen refresh rate (the Hz thingy you will often see printed next to its resolution in product reviews) higher than what your screen is capable of– really, you don’t want to do that.

#USING SWITCHRESX 1080P#

SwitchResX is no magical wand, there is no way to turn your 1080p display into a 4 or 5K one. To access it, simply go to System Preferences and click its icon in the bottom section. Maybe you want things on screen to be a bigger so you can see them from farther away? Or whatever. SwitchResX lives in the Preference Pane folder of your System Library. Yesterday, I mentioned using SwitchResX to create custom screen resolutions when those provided by Apple are not enough to compensate for my bad eyesight.īut you don’t have to have a bad eyesight to create a custom resolution.
