4k hdmi port intermittently notcoming on after sleep

I’ve read of this problem in several posts, but haven’t seen a solution yet. My situation is similar to:


I have a Macbook Pro running Mojave with dual hdmi set up. I downloaded the latest drivers last week. I’ve tried different monitors/cables still the same result. I don’t have another usb-c computer to test on. Unplugging and re-plugging the dock brings the monitor back.

Has anybody had a successful resolution to this? I really don’t like powering down the hub to bring the monitor back. Do I need to handle the dual monitors with a different usb-c adapter?

Thanks for any assistance
