Mobile High-definition Link, or MHL, was a wired connection option that allowed you to connect your mobile devices and screen mirror on your TV. Samsung discontinued the MHL option for their mobile devices a few years ago and went with wireless screen mirroring only.
Screen mirroring (or screen sharing) from your mobile devices allows you to share photos, downloaded movies, videos, music, applications, presentations and more directly to your TV screen. Traditionally, MHL to HDMI adapters were the go-to solution. These adapters simply connected your phone via a wire to your TV through an HDMI port. Now there are wireless options available that eliminate the need for a wired connection.
Wireless Screen Sharing Options
A wired connection is no longer the option of choice for sharing mobile device screens to a TV or projector screen . Wireless display receivers or adapters are a great replacement for the wired MHL to HDMI connection. Simply plug in the wireless display adapter and connect your mobile device wirelessly.
Some, but not all, wireless display adapters create their own direct wireless connection, allowing you to connect WITHOUT using Wi-Fi, so it won’t slow down your home network by taking up bandwidth.
Miracast is a wireless display standard that is built in to many Android and Windows devices in order to screen share to a TV.
