Macbook 2016 HDMI output flickering

Hello guys, i have a long problem with using bootcamp and windows 10 on macbook pro - i have a flickering like this

You don't need add photos from a different web site:

Once again, the Apple Digital Multiport adapter is junk. Note that it's 2 star rating on Apple's own web site is well earned:

Do yourself a favor and buy something from another source. I have had success with HyperDrive adapters.

Add me to the list.

• 2016 15" MBP clamshelled
• Apple USB-C to T-bolt adapter
• Apple T-bolt cable to LG 34" Ultrawide

I do put it to sleep each night.

Mind blown by the number of folks also reporting this issue and that it hasn't been resolved.

Same issue being reproduced with my external monitor going blank at irregular intervals. Screen will blank out once every 5 minutes or even 10 times in a minute - going blank for about 5 seconds on average.

• 15" MBP top line (2017)
• Apple USB-C Power/HDMI/USB hub
• DELL U3415W Display
• HDMI Cable connection

I eventually caved and bought one of these:

It worked so well that I ended up buying 2 more.

Added benefit: I realized (only when I bought the Neo-C, not the Neo-X) that my office has GIGABIT ETHERNET! I can now upload/download files at 900mbps, consistently.

I plug in one cable when I get to work, and I have:

• My USB goodies all hooked up
• HDMI monitor
• Power cable
• Memory card
• Ethernet

Pretty amazing.

Best part? No flickering, no cutting out, no BS. Works perfectly, every time, in every port.

Hello. Did you return your Macbook or get this fixed? I just found this thread after putting up with the display issue for the last three months. I've been a Mac user since the early 90's and this is the worst Mac I've ever owned. Sad. I was so excited to get it. I'm in sales and connected to external displays is what I do. Doing a restart every time is not feasible. Thanks for starting this thread. I wish the last page didn't end with the issue still unresolved. Not sure that I have any options other than sucking it up and continuing to install beta software.

My issues have completely gone away after upgrading to 10.12.2. I had constant flickering in os x but had never tried bootcamp. It was a frustrating couple months but I'm pretty happy with my setup now.

it could just be hardware related but try downloading the drivers again just to be sure. it could be something to do with the digital AV adapter but you mentioned it worked fine on the 2015 MacBook. I think this may be relevant to windows. Try contacting Microsoft and see if they have any support for the new MacBook. If not it is most likely to be drivers. It is likely that the usb c port is faulty though. Make sure your Mac OS X and Windows 10 is updated to the latest and then try re installing the drivers.

I have this issue too, with a MBP 2016 15" and a Samsung SE790C ultrawide monitor. It's driving me absolutely bonkers!

The Samsung monitor is connected via HDMI (with the official Apple USB-C Digital AV Multiport Adapter) and every now and then it will just flicker and then the screen will go black for a few seconds, and then the picture will reappear. Happens pretty regularly. Really don't understand what's going on. Any ideas anyone?

Upgraded to 10.12.3 Public Beta yesterday but made no difference.

I'm running a MBP 2016 15" with dual Samsung UE590 4K monitors connected via HDMI (with the official Apple USB-C Digital AV Multiport Adapter). Screens flicker after waking from sleep. Noticed that one flickers nearly continuously while the other screen flickers once every couple of minutes.

Upgraded to 10.12.3 today. Issue remains.

I too am having this issue with a few additional observations.

I'm using a usb-c to hdmi adapter.

When I unplug the external monitor/4k via the usb-c adapter and plug it back in later, there is no response at all from the monitor/4k. If I unplug the hdmi cable from the adapter and reseat it in the adapter, the monitor comes on, BUT it comes on at a resolution that is larger than the viewable space on the monitor. When in this mode, I experience the flickering. It seems as if a true sync (of resolution) is not being achieved and the software is repeatedly attempting to adjust the resolution/positioning. I can reboot while the monitor is plugged in and upon restart it will sync and behave normally.

Another important workaround is that I can resolve this by opening the display settings and modifying the resolution on my external monitor to something that is not supported (e.g. 1600x900) and then gather the windows on the laptop before returning the setting to 3840x2160. When it resyncs at 3840x2160, the screen size is correct and there is no more flickering.

This is obviously a behavior condition on the part of the software as the hardware shows no diagnostic errors and functions normally otherwise.

Apple please let us know if there is a proper tracker created for the appropriate developers and a link to any other forum thread that is being officially monitored/responded to. This is a highly impactful bug.

We're a tolerant lot aren't we? Seems that there's been an issue with video output since the release of the 2016 rMB and still here we are. This is beginning to feel more like hardware than software and yet Apple (despite reaching out to a few of us initially) are silent on the matter. Must it always take a class action lawsuit to get them to admit to anything wrong with their hardware?

I've used multiple laptops and multiple monitors, and the problem persists. Purchased a HooToo HDMI dock/adapter and it works without a single flicker or pop, where I was getting them constantly with the Apple adapter.

Can people who do return/replace under warranty please post their experiences. I bought mine from Currys in the UK and they're telling me they will not refund/replace, I'm to follow standard fault procedure. If Apple would just admit it's a hardware/design fault it would be hugely useful but I cannot see that happening.

Cheers,

Seems I have a somewhat related issue:

On my Macbook 2016 with an Anker USB-C HUB with HDMI output plugged onto my video projector, the display is gone sometimes after a few minutes, sometimes even seconds. This is totally random, and I'm sure it's not the cable because the old Macbook Pro 2010 of my wife works perfectly.

I initially thought the issue was from my adapter, then I found this thread which makes me worry... I absolutely need stable video output because I plan to use my macbook for DJing and VJing at the same time, so I can't just unplug/replug the adapter when the display is gore as it will also cut the audio!

For a device of this price with this kind of voluntary limitation (only 1 port for everything!), it is not acceptable to have this kind of issues, still unresolved months after the release.

What can we do???
