Anker USB C 8 in 1 Power Expand

Hi All - I just purchased an 8 in 1 power expand and when I connect this to my Macbook pro 2020 it cycles the display on and off on my Samsung UHD 28" monitor.
If I use the Apple adapter its fine but through either of the HDMO ports on the Anker it doesnt work.

Here is a video of the issue

Any ideas please its driving me crazy.

Thanks Jim

Hmm no idea what’s causing that issue. I’d just ask for my money back

I have a Dell laptop using the same Anker USB C 8 in 1. It has two HDMI ports and once I connected the Anker to the laptop and two additional MSi screens using the 2 HDMI ports on the Anker, one correctly displays resolution and the other does not. I thought maybe it was a screen issue. However, when I only plug one screen in at a time both screens have proper resolution. It’s only when I plug both screens in that one will have proper resolution and the other does not. I’m starting to think the Anker USB C 8 -1 does not fully support 2 screens using the 2 HDMI ports. Is that correct?
