DisplayPort to USB-C Monitor with a Single Cable?

I ended up picking up a Lepow USB-C monitor on Black Friday to try out for work and personal.  While the package includes all the necessary cables and power adapters to run via USB-C to USB-C or HDMI to mini HDMI + USB-C power (which I have already used both ways), I was wondering if there is a cable which can go from a GPU DisplayPort output to USB-C with power delivery which would make it a single cable operation similar to USB-C to USB-C.

I've seen another post which was talking about USB-C output (computer) to DisplayPort input (monitor), but that's not what I want.  I would like to do the opposite.

Does this exist?  Has anybody tried this?  I assume there is little to no market for this as it would just eliminate the need for external USB-C power to the Lepow USB-C monitor if using the HDMI to mini HDMI cable, and if there was a cable, I'm sure it would cost at least $25-30.

@omardesu There's no one DisplayPort output connector to one USB-C output connector with bus power. The closest one to it is Huawei VR-2 [discussion link]. I used one with my ASUS MB16AC USB-C monitor. The cables need bus power from USB-A to feed the portable monitor.

@itsage That's what I figured... Interesting solution though!

Requires more than one cable (power needs to come from somewhere).

The Lepow seems to be small/low power like the Asus, so the Huawei VR-2 cable should be sufficient. A review on Amazon said the Lepow took between 3.5W to 6.69W depending on brightness. I'm not 100% sure this is safe though. USB 2.0 is 2.5W. USB 3.0 is 4.5W. You need battery charging or power delivery to get more.

Thanks for the info!  Seems like a hefty discussion there...  Too much for me to actually care about at this point, TBH.

One more USB-C cable for power delivery isn't that big of a deal for me.  It is my first few days with the Lepow display, so I'll get some idea of how I'll be using it during my normal work week soon.  The most elegant solution would be for my work laptop and travel SFFPC to have USB-C so I could just carry one cable, but one extra cable isn't that big of a deal.

However, this is yet another exercise where I wish there was more USB-C implementation.  I like the simplicity and added capability that it has.  Hopefully, the general public can start gravitating that way also in the future...
