I got a 4K display for my MacBook (late 2013) but I'm unable to scale everything after this monitor plugged. (Browser content is scaled, but the system app is not.) enter image description here

Can I still scale everything with external display? enter image description here


When opening the Display preference pane in MacBook/MacBook Pro, additional floating window is displayed for the connected external display. The scaling and resolution settings for the external display can be adjusted in that window.

For additional instructions, refer to the Apple Support Document, macOS Sierra: Adjust your display’s resolution.

Set the resolution for a connected display If you have more than one display, additional resolution options are available.

After the display is connected, choose Apple menu > System Preferences, click Displays, then click Display.

Press the Option key while you click Scaled to see additional resolutions for the second display. Then select a scaled resolution option for the second display.

  • Can you take a look at the 1st screenshot? There are options but they would all decrease the resolution. – Rahn Jul 18 '18 at 16:09

    There is no such option available where you can scale the display without changing the resolution. – Nimesh Neema Jul 18 '18 at 16:44
