DipslayPort 4 lanes are supported through usb type-c alternate mode. USB power delivery and usb 2.0 is always supported with the displayport alternate mode.
Powerdelivery is not crucial however usb is so critical for me. I need a passive type-c dp output with a usb 2.0. However I cannot find any low cost passive type c converter with these features.
According to this paper it should be possible: https://www.vesa.org/wp-content/uploads/2016/10/USB-DevDays-DisplayPort-Alternate-Mode-2016-final4.pdf
Do I understand something wrong? Does anybody know any kind of schematic that I can make this at least by myself?
