Change the orientation in your OS Display Settings and ensure your stand supports physical rotation. Use vDisplay Manager for automatic switching.

1. Physical Adjustment: Tilt the screen back and raise the stand to its maximum height before rotating 90 degrees clockwise.

2. Windows 10/11 Setup:

• Right-click on the desktop and select [Display settings].

• Locate the "Display orientation" dropdown.

• Select [Portrait] or [Landscape].

3. macOS Setup:

• Go to [System Settings] > [Displays].

• Find the "Rotation" option and select [90°].

4. Smart Solution: Download ViewSonic vDisplay Manager. Enable the [Auto Pivot] feature to have the OS orientation change automatically when you rotate the hardware.

Note:  

Warning: Do not force the screen to rotate if the stand does not support it. Check if your model has a "Pivot" feature in the user manual.
