    I don’t know shit about cables but it’s plugged into a monitor. My intuition is that a monitor shouldn’t be pushing power out through a video input port.

      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.

      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.
