Received it several weeks ago but tried it a few time but I don't understand how it works. There is no manual. If I put it on the electricity or without I don't receive anything on my phone (oneplus 3) or laptop (xioami Air 13). Could anybody please explain to me why my phone nor my laptop see this device. I would love to connect my computer screen with my laptop.
