Anyone seen a cable that combines HDMI, USB and DC into one cable?

well this is not for VR, but i guess i will look in there
Virtuallink is basically the same as USB-C with DP Alt Mode with some predefined PD (~14W and 27W, iirc). It's only difference is it adds an "alt mode" for the USB 2.0 data pair (that data pair is implemented using 4 wires, as to support simple reversibility). That "alt mode" moves USB-C's 4 USB 2.0 wires to USB 3.0 mode (diff pair up, diff pair down). Virtuallink actually instantiates as a regular DP Alt Mode + PD first (this includes the USB 2.0 link that is always present in USB-C [DP also, but that's outside of the scope of this conversation]), then it polls for the "USB 2.0 -> 3.0 alt mode" after the connection is initially made.VirtualLink was supposed to solve this problem for you, but as you can see nobody is banging down the door to create a compatible adapter.
This is the best discussion I can find.
Even the Valve Index lacks VirtualLink support. Looks like it's doa, and you're just going to have to deal with the cable mess.
That, or buy one of the wireless kits for VR headsets?
You knowe, we have a VR subform for this, right?

However, if you don't have a Virtuallink device, and just plug a regular USB-C (with DP alt mode and PD requirements) into a Virtuallink port, it will work normally. This is one of the things, where I hope USB4 will actually supplant Virtuallink on GPUs.
Also, yeah, it would be helpful if we got a better picture of what this was all for.
its to plug in a touch screen monitor (HDMI, USB, DC) to a PC.
its an older monitor, so no USB-C.
