DisplayPort can indeed provide power, but with some limitations. The standard DisplayPort connector can deliver power up to 3.3 volts at 500 mA. This is suitable for powering small devices like active cables or adapters, but not enough for larger devices. For devices requiring more power, external power sources are necessary. When planning your setup, consider the power needs of your devices and whether DisplayPort's power delivery capabilities align with those needs.
