When a circular screen displays square shapes, it is usually due to display settings or screen adaptation issues. Here are some potential solutions and steps to address the problem:

1. Check Display Settings:

   - First, check the display settings of the device to ensure the display ratio or resolution is set correctly. For most devices, the standard display ratio is 16:9, but this may vary depending on the device.

   - If the device allows, try adjusting the "scaling" or "fit" options in the display settings to see if this improves the issue of the circular screen displaying square shapes.

2. Check Screen Adaptation:

   - If the problem occurs in a specific application or interface, it might be due to the application not being adapted for a circular screen. In this case, try updating the application to the latest version or check if there are screen adaptation options in the application's settings.

   - If you are a developer and are developing applications for circular screens, you may need to use specific development tools or libraries to ensure the application displays correctly on circular screens.

3. Check Hardware Connections:

   - In some cases, display issues may be due to hardware connection problems. Check all device connections, including screen and power connections, to ensure they are properly connected and not loose.

4. Check Drivers:

   - If the device's display drivers are outdated or corrupted, it can cause display issues. Try updating the device's display drivers to the latest version or uninstall and reinstall the drivers.

5. Consider Hardware Faults:

   - If the above methods do not solve the problem, there may be a fault with the device's screen hardware. In this case, it is recommended to contact the device manufacturer or technical support team for further assistance and repair.

6. Use Third-Party Tools or Software:

   - In some cases, third-party tools or software may help resolve the issue of circular screens displaying square shapes. These tools or software may include screen calibration tools, resolution adjustment tools, etc. However, ensure that any third-party tools or software are from trusted sources and compatible with your device.

In summary, when a circular screen displays square shapes, first check the display settings and screen adaptation issues. If these methods do not resolve the problem, consider checking hardware connections, drivers, and potential hardware faults. Before attempting any solution, be sure to back up important data to prevent accidental loss.
