USB Type C only Connection

[dirtaykookay92]

So I bought a generic portable monitor that claims that it can deliver power and video off of one type C cable. After I ordered it I had my doubts it would work and decided to look it up online, multiple websites said it should not work because of the GPU Type C being used only for VirtualLink. Well it arrives and I try it anyway, happy to say that when I plugged it into my RTX 2070 Armor it worked. I than read the manual and it said phones need to support 3.0 and PCs needs to support Thunder-port .

My question is why does this work, how does it work, is the GPU Type C a Thunder-port or a different type of video standard , will this still work if I change my GPU to a different GPU from NVIDIA or AMD that has a Type C, will this work for all monitors that claim power and video off of one Type C or did I get lucky, and how was your day?

USB-C supports Displayport. "DisplayLink" is a separate software-GPU that speaks USB.

 

If you plug a USB-C monitor into a USB-C port, it is either going to use the Displayport-alternative, HDMI-alternative or Displaylink-over-USB protocol. The catch is that the monitor needs power to do so, and while USB-C GPU's certainly have that power, at least high end models do.

 

Now, as for "is it actually a monitor", Displaylink is software, so you're not going to be able to play games on it if you make it the primary monitor. If it's using DisplayPort or HDMI alternative mods, then it's simply another monitor to the GPU. So check what Windows actually says is plugged in. If it's showing up as an additional GPU, then it's basically a software GPU, and you should not use it as the primary monitor.
