I have a new Dell projector 4350.
The store that sold it to me sent it with a TP-link usb wi-fi adapter (TL-WN725N). When I insert this adapter to the internal USB port and I choose the source "Wireless Display", I get a message that no Wireless adapter was found.
But in the manual says that the Wireless adapter attaches to an internal HDMI port powered by the internal USB PORT.
I think this should be a very specific adapter (maybe Dell Brand), and not any USB->Wi-Fi adapter.
Thank you very much,
