#178176 — USB3 Monitors

Does anyone know whether Debian (or the kernel in general, I guess)
supports USB3 monitors? A quick web search finds no mention of it, if
so.

If this support does exist, does that knowledgeable person know whether
a boot console is supported, or the USB monitor can only be secondary,
with a more specialized adapter used for setup? I think I'm asking
whether the stock Debian kernel incorporates USB video support and
autodetection and can thus boot directly to a USB3 console or Xorg
screen. If not, could I compile a kernel to do that?

(I want to do this at least largely to get a
super-low-power-consumption system. USB3 monitors use as little as 5
watts when in active use and even less in standby.)

Thanks for any assistance.

Carl

As far as I am aware, video-over-USB is "displaylink".  Including "displaylink" in your web search may provide results

You may want to consider USB-powered monitors that use a more traditional video connection (such as HDMI).  I've been using a GeChic USB-powered HDMI monitor and I've been happy with it.  It pulls 2 amps off of USB.

Thank you, that was exactly the missing piece.

I will indeed consider doing that. Most of the low-power portable 
monitors I've found for sale
seem to be USB3 single-cable for both signal and power, which seems cool 
to me.

Again, thank you.

Beware -- 2 amperes is too much current for convention USB 1.1, 2.0, and 
3.0 ports found on most motherboards and USB adapters.  You need 
specialized USB ports for devices that draw that much current:
