Macbook 2016 HDMI output flickering

I had the same problem with my 2016 MacBook. I also experienced sporadic disconnects of my external SSD drive. Not cool. It got worse. In the end I could not reliably charge the device. It boiled down to the USB-C connector being faulty and had it replaced on warranty. After that repair the HDMI Adapter worked without a problem.

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.

1st, it wasn't a USB-C hub, it was a USB-C to USB-A and HDMI adapter. It solved my issues with the Apple Digital Multi-port Adapters inability to mount USB-3 external drives. I tried 2 Apple Digital Multi-Port adapters, neither of them would mount any of my USB-3 external drives. Both had their firmware updated to the latest.

I've used the HDMI connection of the HyperDrive 4k HDMI adapter with a 25' long cable on hotel room TVs with no issues of flickering or overheating. It's built better than the Apple adapter and it's $10 less.

All I'm saying is that this post contains a wide variety of issues that mostly appear to be related to the use of the Apple Digital Multi-port Adapter. Instead of trying to put the blame on your Macs or software, dump the Apple Adapter. Return it for a refund and try something else. It wouldn't have to necessarily be a HyperDrive unit, there are other products on the market that probably work just as well.

Or, you can spin hours on the phone with Apple, re-installing software, exchanging hardware, but IMHO, the Apple adapter is a hopeless piece of junk.

Tried to go 50 hertz instead of 60, and i've been stable for a whole day so far!

The real problem is the Apple USB-C Multiport adapter, it's junk. Do yourself a favor and get a: https://www.hypershop.com/collections/all/products/hyperdrive-usb-type-c-hub-wit h-4k-hdmi-support your troubles will be over.

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.

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

https://1drv.ms/v/s!ArD2ImFwJa-soPBpOt-0hoiG4V6J-A

(this is my macbook connected to external monitor - i tried various monitors and usb-c adapters and hdmi cables)

So... This problem persist only if i wake up from sleep only in external monitor via ubs-c hub - if restart macbook no problem

I used various builds of windows 10 - actually fall creators update

I used various display drivers from newest to the old one from apple bootcamp package (1.7.2016 - 20.19.15.4483 release - this is most stable but flickering persist sometimes)

I set all to maximum performance in intel settings and in power settings in windows 10

I have no problem in MacOS.

If I use standard windows display driver or safe mode - no problem - it must be a driver issue - and latest drivers makes a flickering much more than older drivers.

I tried various steps from internet - nothing helps, but i didnt find someone with exactly same problem.

This bug goes me crazy - it must be a solution...

Do you guys have problem in bootcamp or in macos too ? I have only in windows 10.

My Macbook 2017 returned today from assistance, they said using the Apple Cable worked normal, but what happens is that im using Hyper Drive and also already tested in OEM adapter and did not have lucky, I will not spend more $80 in that ****** cable.

Thats mega frustrating I need external monitor to work and my screen flicker every 5 seconds... Where is possible report this? This thread is so old, where is apple to solve this.

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

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

Thank you for posting about this issue. This post is just to add another voice to the same problem, which is beyond frustrating. Working on a 12" MacBook (early 2016, OS 10.12.6) connecting to a 28" ACER B286HK external monitor using the Apple USB-C digital AV multi-port adapter.

Its possible, sometimes, to get a connection and have the external monitor work as expected. Other times it seems to recognize (electronically) that something is attached to the port, but the monitor displays 'no signal'. Then, my favorite, is when the monitor flashes every few seconds, repeatedly. The flashing is frequent enough to induce seizures in people so prone. Display is not even active long enough to use the mouse to select something and potentially change a setting. Yes, sometimes rebooting will lead to stable activity on the external monitor. But really? This is how one "solves" problems in the Windows world, not Apple.

Will also add my voice to sentiments expressed in this thread .... have been a long time, ardent proponent of apple. This is the first computer that has not lived up to expectation. There have been other issues with it, not as relevant to this thread about driving the external monitor, so will not enumerate them here. Like others on the thread I hope to bring this set of concerns to the attention of the powers-that-be at Apple. Please pay attention. Please fix this. The alternative is working on the Windows platform; not an idea I embrace, but with problems like this its difficult to make the case for Apple and difficult to convince IT management, and others, at my University that Apple is the preferred platform.

Start with addressing the ability to drive an external monitor? I'll take it.

Thank you.

Is this issue really still ongoing ?!?!?

It precipitated my departure from Apple in general. I went from a MacBook, an iPad Pro and an iPhone 7 to a Dell XPS15, a Surface Pro 2017 and a Samsung S8. I figured if the user experience wasn't pretty seamless with the Apple kit I may as well have the same with other hardware and get some extra flexibility/value into the bargain. I'm very happy I switched and Windows/Android is not the 'hot mess' people would have you believe.

Apple aren't the company they once were and I cannot see it turning around with the general direction they're headed in.

No one from apple answered till now ?

Do you think that macbook have faulty usb-c since you bought it ?
