    I bought the new USB-C Acer H277HU. It constantly goes black and looses connection. Does the same with the supplied acer cable and the macbook one.

    Ive got the 2016 M5

    Anyone pick up this monitor yet? Or have this same issue with any other monitor?

    I had the same problem with a 2016 m7, though it happened even with the Apple Digital Multiport dongle. It seemed to happen more often when watching videos on YouTube for some reason. I ended up returning the monitor and the MacBook, so I can only say it happened to me too, sorry.

    Saw a video that said you can't use the MacBook charger USB-C cable because it only supports USB 2. So you'll have to use the Acer included cable. That's all I know, sorry but sounds like it's either the monitor or a USB-C hiccup.

    This is the potentially fatal flaw of the USB-C standard, which is that "USB-C" includes no less than three types of cables, all of which look essentially the same but which are not compatible with each other: USB-C 2.0 "charging cables" of the type supplied by Apple with the MacBook charger, which have a 480Mbps data throughput capacity; USB-C 3.0 (and 3.1 Gen 1/Gen 2) "power/data cables" which promise up to 10Gbps throughput; and USB-C Thunderbolt 3 cables which promise up to 40Gbps throughput. All of them look for all intents and purposes exactly the same, but they don't work the same, and how is anyone to know?

    Well, for starters, Apple should have just made their bundled USB-C charging cable support full USB 3.1 Gen 1 speeds even though it's primarily for charging. That way MacBook buyers could also use it for purposes like the one the OP mentioned. That said, issues like this should work their way out over time as USB 2.0 bites the dust and USB-C 3.1 Gen 1 and 2 become the norm.

    As for Thunderbolt 3, at least these are clearly marked with the Thunderbolt logo icon to differentiate themselves both on the cable and the port. By late next year, I'd image most new notebooks will have nothing but USB-C 3.1 Gen 1 or 2 ports and a Thunderbolt 3 capable (and marked) USB-C port on high end models. Basically expecting this from the next generation MacBook Pro.

    I've read reviews on that model and haven't seen any of these complaints. Maybe box it up and take it to the Acer Store's Genius Bar? JK - I'd send it back.

    My guess is that both the macbook and the acer come with the 480mbs USB-C cable, even though both are equipped with the 3.1 port. Explains why they call it a "charging cable"

    No. Acer includes a DisplayPort capable USB-C cable. See this video that has been making the rounds promoting the setup the OP is working with:



    It's a nice setup for people who use the MacBook as a primary Mac. I considered it as well, but ultimately decided to use my MacBook as a secondary Mac with my quad-core iMac as my powerful desktop solution. Plus, it seems like a bad time to invest ~$500 in a 2560x1440 display with 5K Retina options (albeit not for the 2015 or 2016 12" MacBook) on the horizon.

    Same Problem here.
    A technician from Acer says that there is a Problem with the CPU and the USB c Port.

    Interesting, so maybe this monitor has to go back all together, did you end up switching to something different?

    I just got the same monitor yesterday and have not experienced any of the issues that you are having when hooked up to a 2015 MacBook via USB-C.

    Yea im thinking this may be more of a computer/gpu cpu issue. I picked up another monitor thats HDMI and its doing the same thing. Rather than send it in for repair I'm still in the return window, I'm going to return it and buy another, Love computer otherwise.

    I sent the Monitor back.
    They will test it. Perhaps they will repair or change it. Its free.

    My 2016 m7 is doing the same thing with HDMI and a Dell screen. I think it's the computer. If if plug it in, it starts to constantly go black and then on and then black again. If I shut down, do an smc reset, boot it up and plug it in it works perfectly. If I undock it, use it at home, put it to sleep come to work and dock it it happens again.

    So basically it keeps happening without a daily smc reset.

    I also have the problem with my H277HUsmipuz going black for 1-3 seconds once in a while when I'm using with my old MacBook Pro (13-inch, Mid 2010) connected by DisplayPort cable and a Mini DisplayPort to DisplayPort adapter.

    However, if I connect the monitor to a HP EliteBook 1040 by DisplayPort cable I don't have any issues.
