Thanks -- I have a similar adapter. However, the screen is USB-C only (I'm not using USB-C to HDMI or anything like that). What I need is an adapter with basically one USB-C male and two USB-C female -- one for USB-PD and one for the display. I'm not sure if there is something in the USB-C/USB PD/USB3.0/whatever standard which makes this impossible / too difficult.

Why don't you get the adapter I linked to, then another HDMI to USB C to go to the monitor. so Phone -> USB C (power into adapter) -> HDMI -> USB C -> Monitor

It's possible, but might be a bit awkward in how the devices perceive it.
