Im thinking about, which extension cards should you get actually, if you want to have as little as possible power draw in:
idle (no cable pluged in) and,
used (cable pluged in)
And the second thing im interst in is, what is actually the bandwidth-difference, when used as display-connecter.
So first expansion cards im thinking about is USB-C vs DP and USB-C vs HDMI.
1a: Do i have the same bandwith when i use USB-C with DP adapter vs direct DP-expansion card? Would it maybe be possible to use a USB-C to displayport 2.0 or 2.1 adapter to get even more bandwith, than the native DP-expansion card? (which version is the dp expansion card (2nd gen) actually?)
1b: But what about power usage? Does the 2nd gen Displayport expansion card has less power draw in idle than an usb-c (withouth a USB-C to DP adapter connected) ? What about when a display is connected ? Which one does use less power (idle is more important for me) ?
2a: And same about HDMI: But there it is even more complicated, because the HDMI expansion card is only 2.0b but with an USB-C to HDMI 2.1 adapter you should be able to use HDMI 2.1 (so i don’t get the reason for a HDMI expansion card, if it is not HDMI 2.1). Or can you not use a HDMI 2.1?
2b: And also the power-question: Does the 3rd gen HDMI expansion card draws more power in idle? And does it use more, when a cable is plugged in (also idle is more important for me) ?
Is there actually somewhere information (like spec sheets) of the expansion cards and their powerdraw?
3: And then the question about ethernet expansion card: Do you think, an unused ethernet-expansion card does use more power than W-LAN ? And what do you think uses more power, when you use it ?
Extra question: Would it work, if you plug in the ethernet expansion card into a USB-C expansion card? I know this is stupid, but would it work for 1Gbit lan? Because when you don’t want to have the extra-width, you could just plug it out, when you leave home (because i guess you want to use W-LAN then). Therefore you could have an extra USB-C and would not have the extra-width, which the ethernet-card has.
