# 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.

{% hint style="info" %}
**Note:** **Set Resolution** requires virtual machines [with Parallels Tools installed](https://download.parallels.com/desktop/v19/docs/en_US/Parallels%20Desktop%20User's%20Guide/32736.htm). The **Show developer tools** option must be enabled in the **More Options** pane of the virtual machine configuration.
{% endhint %}

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.
