    New reversible USB Type C (rumored for 12-inch MacBook) will offer full DisplayPort



    The next-generation USB “Type C” standard that became available to manufacturers last month will also offer a “DisplayPort Alternate Mode”, enabling the new USB cables to “deliver full DisplayPort audio/video (A/V) performance, driving monitor resolutions of 4K and beyond, SuperSpeed USB (USB 3.1) data and up to 100 watts of power–over a single cable.” That means new USB cables that adopt the new slimmer Type-3 standard can essentially also work as a full-fledged DisplayPort cable. The announcement was made today by The Video Electronics Standards Association (VESA), which worked with the USB 3.0 Promoter Group to offer the functionality:

    VESA utilized the Alternate Mode functional extension of the USB Type-C specification in the development of this new Standard. The DisplayPort Alt Mode repurposes some or all of the four existing SuperSpeed USB lanes to deliver full DisplayPort performance, and uses other signaling available in the USB Type-C connector for DisplayPorts AUX channel and HPD (Hot Plug Detection) function. This enables computers, tablets, smartphones, displays, and docking stations to implement the new USB Type-C connector at both ends while using the DisplayPort Standard over USB Type-C to transmit high-resolution A/V along with USB data and power.

    The result is manufacturers might be able to remove DisplayPort, VGA, and HDMI ports from their devices and offer power, USB data, audio, and video over the single USB Type C cable. Although you’ll also still be able to use USB Type C to drive DisplayPort, HDMI, DVI or VGA displays using an adaptor. Reports claim a rumored 12-inch MacBook Air will arrive next year with USB Type C only for its USB ports and that would make DisplayPort Alt Mode quite important for new MacBook owners in 2015. “By leveraging USB Type-Cs flexibility, the DisplayPort Alt Mode can choose to transmit on just one or two of the four available lanes, so that the other two lanes can be used for SuperSpeed USB data at the same time. In a docking station connection, for example, the use of two lanes for DisplayPort at 8.1 Gbps per lane would allow simultaneous transfer of SuperSpeed USB data (up to 10 Gbps in each direction) while also supporting a 4K UHD (3840 x 2160) DisplayPort monitor.”

    VESA says initial DisplayPort Alt Mode USB Type-C devices will use the current DisplayPort 1.2a, which supports 5.4 Gbps per lane and up to 4K (4096 x 2160) resolutions at a 60Hz frame rate. That means we’ll likely see USB Type C also support the recently announced DisplayPort 1.3 standard that offers a higher 8.1 Gbps per-lane link rate and as a result support for next-gen 5K displays.

    Video explains why you should be really excited about USB Type-C



    OK, so USB Type-C ports aren’t the kinds of things that get people super hyped like new iPhones or Samsung phones. But they’re actually a very exciting development and they came into the spotlight earlier this week when we learned that both Apple’s new MacBook and Google’s new Chromebook Pixel featured USB Type-C ports.

    To explain the importance of USB Type-C, Google this week posted a video in which it breaks down exactly why the new ports are so important to laptops and gadgets.


    Why is USB Type-C so awesome? Here’s the quick rundown:

    You can use it for a lot more than regular old USB ports. The new MacBook’s USB 3.1 port, for instance, delivers the device’s power, USB data transfer, HDMI and VGA capabilities. Or as Google puts it in its video, USB Type-C delivers “power, data and display over one connector, one cable and one port.”

    It’s fully reversible. You know how annoying it is when you try to plug in a USB cable and you realize that you’re putting it in the wrong way? USB Type-C ensures this will never happen again thanks to its symmetrical design — there’s literally no “right side up” or “upside down” in any USB Type C port.

    It’s well positioned to work with more powerful future technologies. USB Type-C can deliver 100 watts at 20 volts. It can output video to 4K and 5K monitors. In Google’s words, “It delivers more power than most devices need today, so it’s going to be able to support many things into the future.”
