Please try inserting the Type-C connector in both orientations (flipping the connector upside down) to check if screen casting works. If the issue persists, consider using a different adapter cable. The Xiaomi Pad 7 supports mainstream adapter cables for screen projection, including Type-C to DP, Type-C to HDMI, and Type-C to Dongle (HDMI, DP). These cables enable direct video output to external displays, ensuring a seamless projection experience.
However, some adapter cables can not fully meet the tablet's screen projection requirements due to variations in cable quality, protocol compatibility, or transmission standards. Type-C to DP and Type-C to HDMI adapters are commonly used for connecting to external monitors and TVs, providing high-resolution video output. A Type-C to Dongle with multiple ports allows for expanded connectivity, including video projection and peripheral connections.
