When the computer screen shows abnormal display conditions such as inverted, skewed, or horizontal orientation, the following methods can be used to return the screen to its original position: 1. Use shortcut keys
1 Windows system: Pressing the "Ctrl+Alt+Up Arrow" key combination can restore the screen to its normal vertical orientation. If the display direction is still incorrect, you can try using "Ctrl+Alt+left arrow key" or "Ctrl+Alt+right arrow key" to fine tune it. Another method is to press the "Ctrl" and "Alt" keys, then press the "up/down arrow" keys to rotate the screen, and press the enter key at the same time to complete the setup. Alternatively, use the "Win+arrow keys" combination key (such as Win+↑ to rotate the screen upwards, Win+↓ to rotate the screen downwards, Win+← to rotate the screen to the left, Win+→ to rotate the screen to the right) to adjust the screen orientation.
2 MacOS system: Pressing "Command+Option+Up Arrow Key" can restore the screen to a vertical orientation. If the display direction is incorrect, you can use "Command+Option+left arrow key" or "Command+Option+right arrow key" to adjust. 2、 Adjust display settings
1 Windows system: Right click on a blank space on the desktop and select "Display Settings". In the "Display Settings" window, find the "Direction" or "Display Direction" option. Click on the dropdown menu, select 'Horizontal' or other correct orientation, and then click the 'Apply' or 'OK' button.
2 MacOS system: Open "System Preferences". In the "System Preferences" window, select "Monitor". In the "Monitor" window, click on the "Arrange" option. In the pop-up menu, select "Rotate" and rotate the screen to its normal position as needed. 3、 Adjust through the graphics card control panel
1. Double click the graphics card driver icon on the desktop (such as NVIDIA Control Panel, AMD Radeon Settings, etc.) to open the graphics card control panel.
2. Find options related to screen rotation in the graphics card control panel, such as "Rotate Display" or similar options.
3. Select the correct screen orientation and click the "Apply" or "OK" button. 4、 Check and update graphics card drivers
If the above methods are ineffective, it may be a problem with the graphics card driver. At this point, you can try updating or reinstalling the graphics card driver:
1. Open the "Device Manager" on your computer.
2. In the "Device Manager" window, locate the graphics card device and right-click on it.
3. In the pop-up menu, select the "Uninstall" option.
4. After restarting the computer, visit the official website of the computer manufacturer or graphics card manufacturer to download and install the latest graphics card drivers. 5、 Other precautions
1. When adjusting the screen orientation, please make sure to save the current work content to avoid data loss.
2. If the screen orientation issue is caused by hardware connection problems (such as loose or damaged cables), please check and replace the cables.
3. If none of the above methods can solve the problem, it is recommended to contact the computer manufacturer or technical support personnel for assistance.
By using the above methods, abnormal display problems such as inverted, skewed, or horizontal computer screens can usually be solved. If the problem persists, please consider seeking professional help.
