How SlimPort Works
SlimPort's technology isn't just some plug-and-play device that works; there are some serious going-ons within the device itself, too. SlimPort connects via your smart devices' microUSB port - do keep in mind that not all devices with a microUSB port are supported since the device itself needs SlimPort tech inside of it. Currently the Google LG Nexus 4 (of course), Google LG Optimus G Pro, Fujitsu Stylistic QH582 and ASUS PadFone Infinity are supported. More supported devices are on their way, we're told.
SlimPort supports resolutions of up to 4K, but most people will use it to output their smartphone's display resolution, which is limited to 1080p for now.
When comparing SlimPort against its main rival, MHL, SlimPort comes out on top, in virtually every category. SlimPort is based on an open standard, where MHL is a proprietary standard. SlimPort is administered by VESA, where MHL is a subsidiary of Silicon Image.
The use of SlimPort is free, versus MHL carrying a license and royalty fee and finally, SlimPort plays nicely with all displays, DisplayPort, HDMI and VGA where MHL is largely just HDTV bridge connectivity.
Analogix have had to put some serious work into SlimPort, but it is 4K ready. 4K may not be a 'here and now' tech for consumers, but it is coming very fast. It's better to build support in and have it ready to go, something SlimPort is capable of. SlimPort supports resolutions right up to 4096x2160 at 30Hz. Where it gets interesting, is what MHL actually supports.
MHL 2.0 is only capable of around 3.0Gbps of bandwidth, which is good for 1080p at 60Hz. SlimPort, with its support of up to 4K resolutions, is capable of 6.5Gbps of bandwidth, which is over double what MHL is capable of putting out.
Analogix have also done this all in the aforementioned super-small cable, compared to the bulky MHL cable. I don't know how they've done it, but they've done it - they've made a 4K-capable connectivity cable that is tiny.
