I have reached the horrible conclusion that I should just buy the official Apple USB-C AV adaptor.
- It's a 'proven' solution for both power and 4K/60Hz with one USB-C slot.
- If it breaks, I can take it straight to An Apple Store (instead of shipping it back to America).
- I can buy a cheapo Anker USB-C hub for my hard drives with no need to use its HDMI out.
Further considerations...
- Will the Apple USB-C AV adapter play nicely with my PixelBook Go?
- Does the Anker USB-C hub need a power supply given, it'll be connected to several hard drives?
I use the official apple adapter coupled with a separate usb A hub for a desktop setup with 4k monitor, Ethernet, 3 usb A devices
I use it most of the time with the MBA but do use it with a windows laptop Also (LG gram)
The former works great.. everything is working as expected with a single connector.
4k60 works.. Ethernet works at 900+Mbps etc..
All Connections are established and system is ready to use in 5 odd seconds after attaching the cable.
The LG also works but with some caveats:
1) it does not charge via the PD from the apple hub. Not sure if it's a apple problem or LG
2) i also need to take the power cable out from the apple adapter before plugging into gram. If i don't , the attached usb devices act iffy (eg Ethernet works but mouse dongle doesn't )
Again , not sure why..
I haven't bothered to troubleshoot as using the LG in docked mode is not an everyday use case and I can live with a couple of wires to attach/ disconnect if and when I need to...
On a side note, I did know that this adapter may not work perfectly with other devices but still chose this because
1) good TB3 hubs are far too pricey currently.. I'd rather buy a mini for a bit more money instead
2) this is the only C hub that I know of which can do 4k60 (4k30 feels noticeabley choppy)
3) stories of bricked motherboards due to 3rd PD hubs are far too common to risk it till the root cause is identified
