PROTIP: If you are having trouble with this dock, unplug the switch from the dock, HOLD the power button on top of the switch for 8 seconds until the menu appears, select power options and restart. Once the switch turns back on, plug everything back in and this dock should start working. I usually have to do this before each session for this dock to work properly. I bought another version of this part from this company but it didn't work for the switch. They refunded my money, updated the listing and recommended this product. So I bought a new one and it works exactly as described! Amazing customer service, they worked very hard to make everything right. This was also tested for Samaung DeX, which also works correctly. Buy from this seller with confidence!
