External display flickering Macbook Pro 16

Hi, whenever I hook my 2019 macbook pro 16inch up to a dell hub via USB-C (charging and display) the display flickers often. I don't have this issue on my 2017 macbook pro 15inch for work.


For reference, the Dell Hub is model WD15 and the external monitor is U2417h


Wondering if anyone has fixed this issue.

MacBook Pro 16″, macOS 11.3

Hello ander2at,


We are sorry to hear that you are having issues with using an external display with your MacBook Pro.


When you connect the external display to your 2017 MacBook Pro, do you use the hub as well? Are you able to connect the display to your 2019 MacBook Pro without the hub?


If you are still having issues without the hub, or are unable to connect it without the hub, try the steps here: Get help with video issues on external displays connected to your Mac


If those steps do not resolve the issue, the next step would be to Get Support here.


Have a great day!
