    Hi All,

    I have the need to use my ethernet usb dongle, plus connect via USB-C to my external 4k monitor via 60 hz as well as have power. Anyway to accomplish this without spending $150?

    Thanks,

    Greg

    Hyper and Satechi make some several ports in one hubs, that's probably the best option

    Thanks, however looks like neither of those support 60hz, which is needed for a 4k monitor..

    So this one supports 60hz on the 12" Macbook? How do you like it?

    Yes, it definitely does. I think it's great. Very reliable and does everything as described.

    To clarify, the CalDigit USB-C dock supports 4K at 60Hz only with a special firmware which consequently limits the remaining ports to USB 2 speeds. Such is the limitation of USB-C. Have you requested and installed this firmware, @BeatCrazy?

    Yes, I installed it and used it with an LG 27UD88 monitor.

    Cool - just thought it worth emphasising to @Gaprofitt that out the box it's limited to 30Hz.

    Just curious: why aren't you just using the built-in ports on the LG 27UD88, given it eliminates the need for a USB-C hub?

    Because I use the CalDigit like a KVM hub because I have both a MB and a 2016 MBP, and it's easier to just switch a single USB-C between 2 different laptops.

    Hi! I wanted to reboot this thread. I purchased a Caldigit USB-C dock to use with my 2017 MacBook 12" (rMB), and I updated the firmware to run a 4K display (Dell P2715Q) at 60 Hz. Unfortunately, I am running into issues on the dock not charging my MacBook-it intermittently stops charging until a different USB load on the ports turns it on again (I am working with Caldigit with a replaced unit to figure this out). So, I have two questions:

    1. Have any others had this charging/not charging issue with their Caldigit dock or 2017 MacBook?

    2. Are there other USB-C dock known to work with the 2017 MacBook that support 4K at 60 Hz?

    USB C currently has the following options by design due to bandwidth limitations:
    1. USB 3 support + 4K@30hz
    OR
    2. USB 2 support + 4k@60hz

    You won't find a hub that does both USB 3 and 4k@60hz because the port can't handle it currently.

    Good to know. However, wouldn't USB-C gen 2 solve this?

    Personally, I'm happy enough with USB 3 + 4Kp30 for the time being, since I only actually need 1080p60. I'll buy a separate dongle for 4Kp60 if I ever decide I need it.

    I suspect by 2019 the MacBook will get Thunderbolt though.

    Does anyone with the Caldigit dock use the Display port connection? If so, how well does it function? Can a retina macbook drive a display on that and the HDMI interface at the same time?

    I use an LG27UD88 at work, but am still looking for a good solution to hook up to my old DELL U3011 at home.
