Yes, the Xiaomi Pad 6S Pro can be connected to an external monitor. It has a USB 3.2 Gen 1 Type-C port, which also functions as a DisplayPort and can output videos up to a resolution of 4K and 60 frames per second.

However, it should be noted that the tablet can only be used as a mirrored screen and not as an extended display. In addition, the tablet screen brightness must be reduced when it is connected to an external monitor, as the tablet screen cannot be switched off.
