External displays flicker on MBP Touchbar

Hi! I'm having issues with my 2016 13" Macbook Pro (w/touchbar), and I'm hoping someone here might have ideas.Whenever I plug it into a display higher than 1080p, it flickers:

I only have three displays, and the one that works is 1080p, while the others (that flicker) are 2560x1440 and 4k.

It happens regardless of how I connect the screens. It flickers when I connect my 4k TV via a CableMatters USB-C -> HDMI adaptor, and when I connect to my 2560x1440 Kogan 27" display by the same adaptor or by a (non-cablematters) USB-C -> DisplayPort cable, which leads me to believe it's not the adaptor/cable themselves.

I took it into an Apple store last week, and we couldn't reproduce the issue with the displays there, which were 5k LG Thunderbolt 3 displays. This makes me think it's an issue with the format conversion.

They took my laptop for further diagnostics, and also replaced the top case (keyboard, touchpad and battery) and display for other reasons - keyboard because of sticky keys (new one has the same issue!) and display because it was clicking while moving. They said they'd replace the logic board if they could reproduce the issue/find a fault through heavy diagnostics, but they couldn't, so the external display issue still remains.

I found a friend who also has the same laptop, and tried my setup with hers, and she experienced the same issues :/ so it's either a macOS thing, or an issue with my cable/adapter. I don't think it's the latter, because both a different brands and different products.

Has anyone else had similar issues, or know how to fix them? I've obviously restarted numerous times, reset pram etc, but no luck.

Thanks!

Edit: Should also note that reducing the resolution of the displays doesn't help, neither does the number connected at the same time.

Same problem over here. I've bought 3 different HDMI adapters thinking that was the problem. It wasn't. I tried presenting on lower resolution external displays and it works fine.

Glad you managed to find some solution to it! Unfortunately lowering the resolution doesn't work for me, but it does make the image buzz strangely instead of flicker

I have the exact same problem, and it has been like this since I got the computer in the beginning of 2017. The problem isn't consistent though. Some times it flickers, some times is just black and sometimes it is working. I have the macbook pro 15", but that shouldn't matter to much. 

I'm now using only the external monitor, closed the lid on the pro, and it seems much more stable.

Are there any apple representatives that follow along here? I thought there would be since it is an apple forum, but I almost never see an official response from them.
