# Change desktop screen resolution with Selenium

The TestingBot Desktop VMs (Windows, macOS and Linux) all support changing the screen resolution before a test starts.

We currently support the following screen resolutions:

 Value Type | Default Value | || string | "1280x1024" | 

 Platform | Resolutions || Windows/Linux | 

- 800x600 
- 1024x768 
- 1152x864 
- 1280x768 
- 1280x800 
- 1280x960 

- 1280x1024 
- 1400x1050 
- 1600x1200 
- 1680x1050 
- 1920x1080 
- 1920x1200 
- 2560x1440

The browser window is not maximized when starting a Selenium test. Changing the screen resolution does not maximize the browser.   
See how to [maximize and resize the browser window](https://testingbot.com/support/web-automate/selenium/browser-window-size).
