The POCO X7 Pro doesn’t support wired video output, so it can’t project the screen on a TV or projector via a USB-C to HDMI adapter.
For your reference, the reasons are as follows:
1. The POCO X7 Pro is equipped with a USB Type-C interface that conforms to the USB 2.0 standard. This does not include advanced protocols required for wired video output, like HDMI over USB-C;
2. The MediaTek Dimensity 8400-Ultra chipset used in the POCO X7 Pro, although optimized for general performance and efficiency, does not include hardware-level support for wired video output functionality;
3. The POCO X7 Pro emphasizes wireless connectivity for screen casting or sharing, allowing you to project content wirelessly to compatible displays.
