I am running Windows 10 in VirtualBox on my retina display Macbook pro. The maximum resolution I can set in the guest is 1920x1440, but I would like to take advantage of the retina display's 2560x1400 display. I have been scouring the internet to no avail, how do I do this?

  • Search for HiDPI and DPI (meaning high dots-per-inch count of pixel density) and PPI (pixels per inch) as the technical terms used for Retina Display on non-Apple platforms. – Basil Bourque Sep 26 '17 at 18:58

As of VirtualBox v6 the settings have changed. You can now use the new screen scaling functionality.

For the selected machine: Settings -> Display -> Screen -> Scale Factor, and use the slider/text field to set the desired screen scaling percentage.

  • That's upsampling, not HiDPI scaling. – Lenar Hoyt Jul 11 at 18:11

In the VirtualBox Manager, navigate to the desired machines settings > Display > HiDPI Support.

Check Use Unscaled HiDPI Output.

In the virtual machine, select your desired resolution.

    What should I do if there is no "Use Unscaled HiDPI Output" option in the Display section of settings? I am using macOS Mojave 10.14.4. – Aleksei Mialkin Apr 27 at 19:06

    Try to set 200% if there isn't HiDPI setting. – Almas Dusal Aug 16 at 6:53
  • I tried then but then it only shows me like the top left 1/4 of the screen and doesn't scale properly. – Robeezy Aug 16 at 19:01
