The flipping of a computer screen is usually caused by unexpected triggering of display settings or screen rotation functions. Here are some steps to solve this problem: 1. Check the shortcut keys
Many laptops are equipped with shortcut keys for screen rotation, such as Ctrl+Alt+arrow keys (up, down, left, right). Try pressing these key combinations to see if you can restore the screen to its normal orientation. 2. Adjust display settings
#Windows system
1. Right click on a blank space on the desktop and select "Display Settings".
2. In the display settings window, find "Display Direction" or similar options.
3. Click on the dropdown menu and select 'Horizontal' (or choose the correct orientation based on the current state of the screen).
4. Apply changes and check if the screen has returned to normal.
#MacOS system
1. Click on the Apple icon in the upper left corner of the screen and select 'System Preferences'.
2. Click on the 'Monitor' option.
3. In the monitor settings window, find the "Rotate" option.
4. Choose the correct rotation direction, usually "standard" to restore horizontal display. 3. Check the graphics card driver program
Sometimes, issues with graphics card drivers can also cause abnormal screen display. You can try updating or reinstalling the graphics card driver to solve the problem.
1. Open Device Manager (in Windows systems, you can right-click on "This Computer" and select "Manage", then find "Device Manager" in the left menu).
2. Expand the "Display Adapter" option, right-click on the graphics card device, and select "Update Driver" or "Uninstall Device" (after uninstallation, the computer may need to be restarted, and the system will automatically reinstall the driver). 4. Check the settings of the external monitor
If an external monitor is used and supports screen rotation, the problem may lie in the monitor's settings.
1. Press the menu button on the monitor to enter the settings interface.
2. Find the screen rotation or orientation setting option and adjust it to the correct orientation. 5. Restart the computer
If none of the above methods can solve the problem, try restarting the computer. Sometimes, a simple restart can solve some display settings issues. 6. Seeking technical support
If the problem persists, it may be necessary to contact the computer manufacturer or technical support personnel for more professional assistance.
Turning the computer screen upside down is usually a problem that can be solved through simple settings and adjustments. Following the above steps, in most cases, the screen can be restored to normal display.
