# 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 \| \| macOS \| - 800x600 - 1024x768 - 1280x768 - 1280x800 - 1280x960 - 1280x1024 - 1366x768 - 1440x900 - 1600x900 - 1600x1200 - 1680x1050 - 1920x1080 - 1920x1200 - 2048x1536 \| |

```java
ChromeOptions options = new ChromeOptions();
options.setCapability("platformName", "WIN11");
options.setCapability("browserVersion", "latest");
options.setCapability("screen-resolution", "1920x1080");

HashMap<String, Object> tbOptions = new HashMap<>();
tbOptions.put("key", "API_KEY");
tbOptions.put("secret", "API_SECRET");
options.setCapability("tb:options", tbOptions);
```

```python
from selenium.webdriver.chrome.options import Options as ChromeOptions

options = ChromeOptions()
options.set_capability('platformName', 'WIN11')
options.set_capability('browserVersion', 'latest')
options.set_capability('screen-resolution', '1920x1080')
options.set_capability('tb:options', {
    'key': 'API_KEY',
    'secret': 'API_SECRET'
})
```

```javascript
const capabilities = {
  platformName: 'WIN11',
  browserName: 'chrome',
  browserVersion: 'latest',
  'screen-resolution': '1920x1080',
  'tb:options': {
    key: 'API_KEY',
    secret: 'API_SECRET'
  }
};
```

```ruby
options = Selenium::WebDriver::Chrome::Options.new
options.add_option('platformName', 'WIN11')
options.add_option('browserVersion', 'latest')
options.add_option('screen-resolution', '1920x1080')
options.add_option('tb:options', {
  'key' => 'API_KEY',
  'secret' => 'API_SECRET'
})
```

```php
$capabilities = [
    'platformName' => 'WIN11',
    'browserName' => 'chrome',
    'browserVersion' => 'latest',
    'screen-resolution' => '1920x1080',
    'tb:options' => [
        'key' => 'API_KEY',
        'secret' => 'API_SECRET'
    ]
];
```

```csharp
ChromeOptions options = new ChromeOptions();
options.PlatformName = "WIN11";
options.BrowserVersion = "latest";
options.AddAdditionalOption("screen-resolution", "1920x1080");

var tbOptions = new Dictionary<string, object>
{
    ["key"] = "API_KEY",
    ["secret"] = "API_SECRET"
};
options.AddAdditionalOption("tb:options", tbOptions);
```

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).
