Why has my computer screen gone sideways?

**Why has my computer screen gone sideways?**

Has your computer screen suddenly turned sideways and you’re left wondering what caused this sudden change? Don’t worry, this is a common issue that many computer users experience. While it may seem puzzling at first, there are a few reasons why your computer screen may have gone sideways. Let’s explore some of the possible causes and solutions:

1. **Accidental keyboard shortcut**: One of the most common reasons for a sideways screen is inadvertently triggering a keyboard shortcut that rotates the display. Pressing certain key combinations, such as Ctrl + Alt + Arrow keys, can cause your screen to rotate 90 degrees.

2. **Graphics card settings**: It’s also possible that the settings on your graphics card may have been modified, causing the screen to rotate. Check your graphics card control panel or settings to ensure that the rotation option is set to “0 degrees.”

3. **Display driver issues**: Outdated or faulty display drivers can sometimes result in screen orientation problems. Updating your display drivers to the latest version provided by the manufacturer may solve the issue.

4. **Multiple monitors**: If you’re using multiple monitors, a change in display settings can cause a specific monitor to rotate unintentionally. Check the display settings and ensure that each monitor is set to the correct orientation.

5. **Physical movement**: Sometimes, physical movement or accidental bumping of your computer can cause the screen orientation to change. It’s possible that your screen rotated due to a slight disturbance.

6. **Software glitches**: Occasionally, software glitches or conflicts can cause your screen to rotate unexpectedly. Restarting your computer or closing any recently installed programs may resolve the issue.

7. **Malware infections**: Though rare, malware infections can also result in a sideways screen. Running a thorough scan with antivirus software can help detect and eliminate any malicious programs causing this problem.

8. **Third-party software**: Some software applications, particularly those related to graphics or display settings, can modify your screen orientation. Checking the settings within these programs and disabling any rotation options may fix the issue.

9. **Operating system updates**: In some cases, updates to your operating system can inadvertently alter display settings, including screen orientation. Review the display settings after updating your OS to ensure they are still correctly configured.

10. **Hardware issues**: In rare cases, hardware problems, such as a faulty graphics card or loose connections, can cause your computer screen to rotate. It’s worth checking the hardware components and connections to rule out any issues.

11. **User settings**: It’s possible that you or someone else using the computer accidentally changed the screen orientation within the display settings. Double-checking the display settings and reverting any changes may solve the problem.

12. **Operating system bugs**: Occasionally, operating systems can have bugs that lead to strange behavior on your computer. Keeping your OS up to date with the latest patches and fixes can help resolve such issues.

In conclusion, a sideways computer screen can be a puzzling and frustrating experience. However, in most cases, it’s caused by simple keyboard shortcuts, display settings, or software-related issues. By following the troubleshooting steps mentioned above, you should be able to correct the screen orientation and resume using your computer normally. Remember to check for any hardware or software updates to prevent similar issues in the future.
