The primary difference between these wireless technologies and their wired counterparts-aside from the wires-is that instead of mirroring your phone’s entire display on the TV (which is all that’s possible with MHL and Slimport), you can pick and choose what is shown. Like MHL and Slimport, these are two means to the same end. The good news here is that there a couple of different types of connections that allow just this: Google Cast and Miracast. The same goes for TVs, though this is a simpler hurdle to jump thanks to breakout boxes-even if your TV doesn’t have direct support or MHL or Slimport, you can still use an active cable to make the connection work. For example, the last two Google phones (Nexus 6P/5X and Pixel/XL) are both lacking either standard, as are the last several Samsung Galaxy phones. The biggest issue with these wired options is support. What was once standard in most smartphones, both MHL and Slimport are becoming harder to find in both TVs and smartphones. ![]() This also provides a bit of juice to the host device, which is a nice touch since the display has to remain on while the phone is connected (regardless of the standard used). ![]() ![]() Like active MHL cables, Slimport requires a “breakout box,” which is essentially a way for the unit to get power. Aside from the added flexibility in choosing a port type, though, Slimport works pretty much the same way as MHL. The big difference with Slimport is that aside from HDMI, it can also output the signal to DVI, VGA, and DisplayPort. Slimport, by comparison, works in much the same. ![]() Passive cables do not require separate power. Instead, they’re designed to be used with an MHL-ready TV, something that’s becoming increasingly uncommon. They work with essentially any TV because they perform the actual conversion, but to do this, they require an additional power source (usually in the form of a built-in full-size USB plug). Passive cables do not do any conversion themselves. There are two different types of MHL cables available: active and passive.
