Bought a USB-C CSV-1560 for my Lenovo Yoga (4k configuration, 4k external HDMI monitor).
The external monitor *rarely* gets recognized by the laptop, and just works.
Without touching cables, the next day, the set-up won’t work – the Laptop does not see the external monitor at all (monitor not detected in Windows 10). Multiple restarts etc don’t solve the issue.
A few days later, suddenly, the monitor might be recognized again.
Tried, asked colleagues to try, we can’t solve the issue.
Is there a way to diagnose at what level the problem happens?
