I'm looking for a good cheap USB-C/thunderbolt dock that supports one monitor @ 1440p60, and has at least 2 USB-A ports. Also keen to have gigabit ethernet but that's less critical. I don't need passthrough power (as my laptop is too hungry for that), so it should be a 'passive' hub, i.e. powered by the computer.
More broadly: There are many, many little hubs like this on Amazon, almost all of which support power passthrough via a PD type C port that you plug a power brick into, and support "HDMI 4K@30hz, 1080p@60hz", can I be confident that these will:
- support 1440p60
- work in a passive mode, i.e. not require an external power source plugged into it
