https://us.community.samsung.com/t5/Galaxy-S22/Samsung-Dex-not-connecting-to-Windows-PC-using-USB-cable/m-p/2202810#M6113 So I tried a few cables/docks I have and noticed this...<BR /><BR />Straight usb-c to hdmi cable works 100% of the time.<BR /><BR />Docks will pass through power need the power plugged in AND it needs to be a decent power supply that needs to be plugged in before plugging in the dock. Example... I tried a raspberry pi 3 power supply with a micro-USB to USB adapter and reliability was bad... Sometimes I'll have video, other times I wouldn't.
