Your Phone Will Soon Spew 4K Video From Its USB Port

The Mobile High-Definition Link (MHL) standard, beloved of Roku and Android phone manufacturers, is about to get exciting: an update coming in September will allow phones to spit out 4K video from their USB ports.

The upgrade, MHL 3.0, will add 4K support to the increasingly popular media standard. It will allow mobile devices to pump out 3840×2160 video at up to 30 frames per second — that's up from the 1080p capability of MHL 2.0. The new standard can also transmit data and video simultaneously, and will allow a device to draw up to 10 watts of power to charge at the same time as providing video.

Unlike competing standards like Miracast and AirPlay, MHL 3.0 requires a physical cable connection, using adapters to connects a mobile device to a TV. But none of the competition — including the wired SlimPort system used by Google's Nexus devices — currently offers support for 4K. So, if it's high-definition or nothing for you, you should be pretty fired up by the fact that the new standard — backed by the likes of Nokia, Samsung, Toshiba and Sony — becomes available in September.

    Erm.. this is probably a silly question but when you say "an update coming in September" that would have to be the next iteration of the device, not a patch...No..? Cos if it's a patch, I just bought a Roku 3, so WooHoo.. :) Now if I can just get the bloody thing to work through my router with a US Address for Netflix....

    How the hecl can an android device power a 4k display via its usb port, when Thunderbolt 2 (with 2 10gbps ports, full duplex) can only power one? :S *This does not compute*

    "The Z87-Deluxe/Quad ATX motherboard is the first to offer Thunderbolt 2, which combines four 10Gbps Thunderbolt channels into two bi-directional 20Gbps Thunderbolt 2 ports. If you’re interested, that’s four times faster than USB 3.0 — enough to drive two 4K displays at once."

      did you actually read the article?" The upgrade, MHL 3.0, will add 4K support to the increasingly popular media standard. It will allow mobile devices to pump out 3840×2160 video at up to 30 frames per second — that’s up from the 1080p capability of MHL 2.0. The new standard can also transmit data and video simultaneously, and will allow a device to draw up to 10 watts of power to charge at the same time as providing video." It doesn't state anywhere that a device will power a display.....

        I think he was confused by "enough to drive two 4K displays at once.". He thought it meant "enough to power two 4K displays at once".

        I never said that they will power the displays. These motherboards, via TB2, can DRIVE 2 4k displays at once, ie spit out 4k graphics for 2 displays, using a 20gbps link.

        How can a phone, via USB, accomplish the same task? Even if this is for future phones, and not current models, how is it possible?

        If I'm confused/wrong, please explain to me why, it's currently 12:45AM and I am very tired, so i could just not be thinking clearly..

          to quote your post..."How the hecl can an android device power a 4k display via its usb port, when Thunderbolt 2 (with 2 10gbps ports, full duplex) can only power one? :S *This does not compute*"...pretty much says it all...

            My apologies. When I said "power" I was referring to bandwidth, and not an electrical current.

    So, if it’s high-definition or nothing for you/q>

    Not to be pedantic but that sentence should have started as "So, if it’s ULTRA high-definition or nothing for you....". HD and FHD are already pretty bum standard nowadays.
