Does my Lumia phone support TV-out?

Lumia phones do not support TV-out feature via cable but you can wirelessly show pictures and videos on your TV using the DLNA feature. With the free Lumia Play to application for Lumia phones you can connect to other DLNA capable devices (TV’s, Blu-ray players, Win 7 Media players etc.) via WLAN network.

You can download the Lumia Play to app from the Store.
