Guys, a while ago the first true solution has come out - but I have been too busy and forgot to report it. https://buywacom.com.au/wacom-link.html Combines DisplayPort and USB into USB-C with alt-mode (to use the Wacom MobileStudio Pro as a monitor / drawing tablet for a computer). This video seems to demonstrate it: By the way, I believe that every laptop and smartphone with USB-C should be able to accept DisplayPort input to the internal display (either internal display needs to have multiple inputs, or the two will be switched to one input with a mux). The only thing that is unclear is power delivery. The Asus Zenscreen only powers from the same USB-C port as the video, and this adapter may or may not deliver any power from the USB-A port to the USB-C port. Assuming that the Zenscreen only needs bus power (5V@3A) which is highly likely, as extremely few laptops (and even desktops) have higher power delivery than this, you could take a USB-C to USB-C cable and shave the outer plastic off the cable, carefully retrieve the voltage lines and wire in another power source. But the danger of this is if the cable is connected to two PD devices which negotiate higher voltage, which would then fry the device you spliced in. You would have to sever the CC lines for this, which might then affect orientation detection. The only proper way to do it would be with a proper device with the mux to deal with plug orientation, and act as a PD source itself. But that is well out of reach of most individuals. I know there are people who are capable, like the person who sells the USB PD Sink Buddy https://hackaday.io/project/20424-pd-buddy-sink so perhaps send him a message and tell him you would pay if he made a device. A device with 4x USB-C female ports, which passes data and alternate modes between two of the ports, but provides PD to each separately through their corresponding PD USB-C port (so each can receive 100W if you have two 100W USB-C chargers). Which by the way, the Wacom MobileStudio Pro 100W USB-C charger is the first and only true 100W USB-C charger that I know of, that serves no function other than as an AC adapter. https://buywacom.com.au/products/ac...power/power-adapter-for-mobilestudio-pro.html Cheers for discussing this stuff, it is so good. And I wish there were more good forum topics about this.
