The Samsung AllShare Cast Dongle could be useful if you own a Galaxy S III. Not a bad price either.
The Samsung AllShare Cast Dongle (EAD-T10UDEGXEU) can be connected to your HDTV to enable the streaming of content from your Samsung Galaxy S3. The dongle plugs into an HDMI port on your TV set and photos and videos can then be streamed to the TV via Wi-Fi.
Adding yet another wireless solution to your smartphone setup, the Samsung AllShare Dongle is the perfect companion to the Samsung Galaxy S3 official wireless charger, helping to create a tangle-free environment.
