Is there an HDMI to USB type C converter? (With DP alt mode and power delivery support.)

I have a portable touch screen that you can connect to a computer in two ways:

  1. Use an HDMI cable to send video+audio to the screen, then use a USB-C to USB-A cable to send touch input from the screen to the PC and use another USB-C to USB-A cable to provide power to the monitor.
  2. Use a single USB-C to USB-C cable for everything. (Requires the PC to have a USB-C port that supports DisplayPort Alt Mode and that can deliver more than 2W of power.)

The Laptop I want to use this touchscreen with only has old USB 3.0 ports, an HDMI port and a DisplayPort (which is already connected to another external display).

Now i would like to have an adapter that has a USB input, an HDMI input, (maybe also another power input) and a single USB-C output that supports >2W power and DP alt mode.

Does such a thing exist?

I can only find USB-C to HDMI converters and the like, but nothing that has HDMI input and USB-C output.

HDMI and DP has incompatible signaling, so no passive adapters are possible.

You need an adapter with a chip that has an HDMI input and a DP output. Not sure if such a thing exists due to low demand, but good luck.

I have the one below: Drivers a fickle, forewarning.

There is a x4 version as well

Never tried in your configuration, mine is DP out (VGA) to DP in (Card) to USB-C out (Card) to Display

Dell has a guide for HDMI to DP out:

@Methylzero HDMI to DP converters definitely exist:

But thinking about it, my monitor might actually support HDMI Alt Mode as well.

Thanks, but I don’t like the idea of trying to hack a pcie card into my laptop. I’m looking for an external device that can do it.
