I am using this USB C Hub: https://www.ugreen.com/products/ugre...ocking-station

This USB C to HDMI cable for the Studio Display: https://www.amazon.com/dp/B07CL2RHX5...roduct_details

For the Cinema Display I am using this adapter https://www.amazon.com/dp/B072PZN5ZK...roduct_details

and a standard HMDI cable I am using also to connect my iPad to a TV.
