LG G2 has SlimPort support not MHL
LG using the same display output technology in the G2 as the Nexus 4.
LG are well known for having produced the Google Nexus 4.
The Nexus had the ability to have video out via the microUSB port, like many high end smartphones today now offer.
However, there was one slight difference. It used a different standard, SlimPort; not MHL like most others.
Essentially they do the same thing. MHL has an install base of millions, and outputs to the HDMI standard. SlimPort offers something just a bit different: DisplayPort compatibility, which means it can easily output to a variety of video standards.
LG have now used the same technology on the G2 rather than the more common MHL. This will mean that if you want a wired connection to a HD display, you will need a SlimPort adapter.
Alternatively the G2 has Miracast technology built in for wireless streaming of content to a display.
