MacOS Monterey

I am experiencing the same issue with the following configuration:

- MacBook Pro 2017 (Intel i7)
- MacOS Monterrey (clean install, second beta)
- Kensington SD4900P dock
- 3 external monitors connected with HDMI

After a minute or so, the two DisplayLink external monitors plugged into ports 2 & 3 go black but stay awake. The main Alt-mode external monitor plugged into port 1 keeps working properly. MacOS seems to think that the DisplayLink monitors are all still there.

Power cycling the dock fixes the problem for about a minute or so, and then the two DisplayLink monitors black out again.

I am testing this on a standalone MacBook that I use only for checking compatibility with Monterey. If you need any alpha or beta testers for your next driver releases I'd be happy to help!
