DLNA-enabled TVs, for example, can be used as an external monitor without HDMI or any cables. I want to show my large family my vacation pics on my phone but the screen is too small for all of them to see at once. My TV should be Wi-Fi enabled and DLNA-certified and I should have a wireless router too, obviously.
- Connect my phone and TV* to the same Wifi network coming from the same router.
- Using the brand appropriate "device media sharing" program** on my phone and TV I connect them to each other.
- Now I select the video, picture or music file to play and it will be play through my home Wifi network to my TV and maybe vice versa. So everyone can enjoy at once.
*The same can be done with a DLNA enabled music player or anything.
**Media appropriate app can be found by searching up on Google or Youtube or any other search engine.
