How to Fix a Computer Screen That's Rotated Sideways

Rotate Your Screen Back to Normal in Windows or Mac

A sideways screen usually means your display orientation setting has been changed, either by accident or by a keyboard shortcut. The fix takes less than a minute and requires no tools or restart. On Windows, right-click your desktop, select Display settings, scroll to Scale and layout, find Display orientation, and change it from Portrait or Landscape (flipped) back to Landscape. On Mac, go to System Settings > Displays and look for a rotation or orientation menu — the exact location depends on your macOS version, but it will be labeled clearly.

If you cannot find the setting in your display menu, the rotation may have been triggered by your graphics card software instead. NVIDIA, AMD, and Intel all include control panels that can rotate your screen independently of Windows. Search your system for NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Command Center depending on which card you have. Once open, look for a Rotation or Display option and set it back to 0 degrees or Normal.

Key Takeaways

Most sideways screens are caused by a display orientation setting in Windows Display Settings or Mac System Settings, which you can change back in under one minute.
If the setting is already correct, check your graphics card software — NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Command Center — which can override Windows settings.
Keyboard shortcuts like Ctrl+Alt+Arrow keys can accidentally rotate your screen, so disable them if the problem keeps happening.
If your screen is physically rotated (the monitor itself is turned), you will need to rotate the monitor back by hand, not through software.

Check Your Keyboard Shortcuts and Disable Accidental Rotation

Many graphics card drivers allow you to rotate your screen using keyboard shortcuts — typically Ctrl+Alt+Up, Down, Left, or Right Arrow. If someone pressed one of these combinations by accident, or if a child or pet walked across your keyboard, your screen may have rotated without you realizing it. The same shortcuts can rotate it back: press Ctrl+Alt+Up Arrow to return to normal landscape orientation.

If this keeps happening, you can disable the shortcuts entirely. In NVIDIA Control Panel, go to Desktop > Rotate Display and uncheck Enable rotation hotkeys. In AMD Radeon Settings, find Display and toggle off any rotation shortcut option. Intel Graphics users should check Graphics Properties > Display for a similar toggle. Disabling the shortcut prevents accidental rotation but means you will have to use the settings menu if you ever need to rotate intentionally.

Verify Your Monitor Is Not Physically Rotated

Before troubleshooting software, confirm that your monitor itself is not physically turned. A monitor rotated 90 degrees will show a sideways image no matter what your software says. Look at the monitor from the side — the screen should be wider than it is tall in landscape mode. If the monitor is actually rotated, you will need to rotate it back by hand. Most monitors have a stand that allows you to pivot them; check underneath or behind the stand for a release button or lever.

Some monitors are designed to rotate and lock into portrait mode for specific work like document editing or coding. If your monitor has this feature and is locked in portrait, look for a physical lock or release mechanism on the stand. Once unlocked, rotate the monitor back to landscape and lock it in place. If you are unsure how to unlock your specific model, check the manual or search the manufacturer's name and model number plus "rotate monitor".

Update or Reinstall Your Graphics Driver

If the rotation setting is correct in both Windows and your graphics card software but your screen is still sideways, your graphics driver may be corrupted or outdated. Outdated drivers sometimes have bugs that cause display problems, and reinstalling them often fixes rotation issues that settings alone cannot solve.

To update your driver, right-click the Start button and select Device Manager. Expand Display adapters, right-click your graphics card, and select Update driver. Choose Search automatically for updated driver software and let Windows search online. If an update is found, install it and restart your computer. If no update is available, right-click the card again, select Uninstall device, restart your computer, and Windows will reinstall the driver automatically. This fresh installation often clears up display glitches.

Check for Accessibility Settings That Rotate the Display

Windows and Mac both include accessibility features that can rotate your screen. On Windows, open Settings > Accessibility > Display and look for any rotation or orientation options. Some accessibility tools designed for users with specific visual needs can change display rotation as part of their settings. If you see an option that looks related to rotation or screen orientation, make sure it is set to your preferred direction.

On Mac, check System Settings > Accessibility > Display for any rotation settings. Additionally, if you use any third-party accessibility software or screen reader, check its settings — some of these tools include rotation features that may have been triggered. Disabling or adjusting these settings should return your screen to normal.

Restart Your Computer if the Problem Persists

If you have tried all the above steps and your screen is still sideways, a restart often clears temporary glitches that settings alone cannot fix. Save your work, shut down your computer completely, wait 10 seconds, and turn it back on. During startup, your graphics driver will reload and your display settings will reinitialize. Once your computer is fully booted, check whether your screen has returned to normal orientation.

If the screen is still rotated after a restart, the problem may be a hardware issue with your monitor or graphics card rather than a software setting. In that case, try connecting your monitor to a different computer if you have one available — if the screen is still sideways on the other computer, the problem is your monitor. If it displays normally on the other computer, the problem is your graphics card or driver, and you may need to contact the manufacturer for support.

Frequently Asked Questions

Can a virus or malware rotate my screen?

Malware can change display settings, but it is uncommon. If your screen rotated suddenly and you did not cause it, run a full antivirus scan using Windows Defender or a third-party antivirus tool. However, most sideways screens are caused by accidental keyboard shortcuts or settings changes, not malware.

Why does my screen keep rotating back to sideways after I fix it?

This usually means a keyboard shortcut is being triggered repeatedly, or a setting is resetting on restart. Disable the rotation hotkeys in your graphics card software as described above. If the problem continues, check whether any third-party software on your computer has rotation features enabled.

Will rotating my screen damage my monitor?

No. Rotating your display through software does not harm your monitor. Physically rotating a monitor that is not designed to pivot can damage the stand or internal components, but software rotation is safe.

What if I want to keep my screen rotated for work?

You can leave your display in portrait or rotated mode permanently if that suits your workflow. The steps to rotate it are the same — just set it to the orientation you prefer and leave it there. Your setting will stay until you change it again.
