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

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.

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.
