Why does the screen display abnormally when mirroring a Mac to the Xiaomi Pad 7 Pro?

When mirroring a Mac to the Xiaomi Pad 7 Pro, the screen can display abnormally due to differences in resolution compatibility between the two devices. The Xiaomi Pad 7 Pro requests to be used as an extended display with its native resolution of 3200 x 2136 pixels to ensure the best full-screen effect.
However, older Mac models can have hardware limitations that prevent them from supporting this high resolution. These limitations can lead to improper scaling of the display output, causing the screen to appear stretched, cropped, or improperly formatted, preventing a full-screen view.
To resolve this issue, consider adjusting the display settings on the Mac or using a lower resolution that is compatible with both devices. This can help improve the screen mirroring experience and ensure a better visual match between the devices.
