How do I set the screen to portrait mode when connecting my computer to the monitor?

The process differs for Windows and Mac systems. Follow these steps: Windows System: 1. Right-click on the desktop and select "Graphics Options" from the menu, then choose "Advanced Options." 2. Next, select "Vertical" as the rotation direction in the "Rotation" menu, and then click OK. Mac systems: 1. Open "Displays" in System Preferences and select the TCL monitor model. 2. Set the "Rotation" option to 90 degrees, and then click Confirm.
