Does Samsung S3 support MHL?
The Galaxy S3 has a different microUSB port than other Android devices, as the port’s pins have been rearranged. That means the Galaxy S3 will not work with standard MHL (Mobile High-definition Link) adapters, which let users connect smartphones that come with microUSB ports to big-screen TVs.
How do I know if my phone is HDMI compatible?
You can also contact your device manufacturer directly and ask if your device supports HD video output, or if it can be connected to an HDMI display. You can also check the MHL-enabled device list and the SlimPort supported device list to see if your device includes this technology.
