ThinkVision M14 doesn't work (MacbookPro 13" 2018 - Catalina OS)

Hi,

I just bought Thinkvision M14 external monitor with DisplayPort type c in alternate mode. But when I tried to connect to my macbook, the monitor didn't response (always go to power saving mode...). Any idea why? Already test it with Dell XPS 14 and it worked.

In theory, my macbook13 2018 should work with DisplayPort alternate mode, right? And it should work with this monitor.

I see some people can get this monitor work:

but there're a thread with similar problem:

Hi fathuraw,

Thank you for visiting Apple Support Communities. It sounds like you're having trouble using your new external monitor with your MacBook. I'd be happy to provide information that may help.

First, take a look at the requirements listed here: Use external monitors with your Mac.

Also, review this article and work through the steps under "If the previous steps don't work": If your Mac doesn't sleep or wake when expected.

Take care.

I can confirm that this is an OS issue (on Catalina). This monitor works perfectly on Mojave, but not in Catalina.

Any helps? Statement? Anything?
