The monitor has to send some data to the computer to tell it what screen resolutions it accepts. VGA, HDMI, and DisplayPort will all do that for sure. Less certain about component, composite, and S-Video.

DisplayPort has a +3.3V 500mA pin specifically for pushing power. In theory, great for powering an active adapter. In practice, has killed motherboards because Dell can’t design a computer for shit.

Friendly reminder that if you use a Dell charger on a HP, nothing happens but vice versa, you damage the motherboard. It kills a chip used for charging. Dell used the same size barrel jack, but they wired it differently from everyone.
