For example, when there are photos and videos that you want to share with family or friends on a large modern screen. A few years ago, not everyone would be able to cope with this difficult task, but today new technologies make it easy to solve it both for modern TVs and for older models. To do this, you must first select the necessary computer devices and applications.
There are three common ways to transfer images from an external screen to a TV:
- HDMI cable
- Chromecast
- Miracast
- EZcast
- AirServer
Mirror photo and video to TV via HDMI
The easiest and most high-quality way to send a PC screen to a TV receiver is to use HDMI. High Definition Multimedia Interface (HDMI) is usually bundled with a TV. It can be purchased at any mobile hardware store. Digital devices of modern TV models using HDMI receive and transmit high-quality images to the screen simultaneously with sound transmission. This method can be used for any mobile devices and laptop models without an HDMI port through a special micro-USB to HDMI adapter, which can also be bought at any gadget store.

Transfer video to a TV via Wi-Fi
Duplication of the screen is easily feasible if the mobile equipment and the TV are manufactured by the same manufacturer, most likely they will have the function of “mirror screen display” (or something similar) on both devices. This will allow without hassle to immediately see on TV everything that is on the smartphone. If the devices are produced by different manufacturers, you need to enable the DLNA (Wi-Fi Direct) function on the TV and download the DLNA application to your smartphone via GooglePlay.
