Changing the Virtual Screen Resolution on the Fly

If you're working with a virtual machine in the Window or Full-Screen view mode, you can easily and quickly change the virtual machine screen resolution. Simply click the View menu in the macOS menu bar, point to Set Resolution, and choose the screen resolution you need.

Note: Set Resolution requires virtual machines with Parallels Tools installed. The Show developer tools option must be enabled in the More Options pane of the virtual machine configuration.

If you're working with the virtual machine in Full Screen on multiple displays, the screen resolution is changed on the display where you selected a new resolution.
