> Another key is that HDMI carries more power than display port. A quick look at Wikipedia's article for both standards shows that you're wrong: DisplayPort: 3.3 V ±10%, 500 mA HDMI: 5 V, 50 mA Which means at least 1500 mW for DisplayPort, and only 250 mW for HDMI. So no, the DisplayPort cable carries more power than the HDMI cable. And when you think about it a bit, it makes sense that DisplayPort carries more power than HDMI: one of the use cases for DisplayPort is an active converter to HDMI, which needs power for both its electronics and the HDMI cable.
