Lenovo C930 External Monitor Not Waking Up After Resuming From Sleep?

2020-09-22, 22:29 PM

Hello all,


I have a C930 Yoga Book with a Dell S3220DGF monitor. I'm running the latest Intel drivers for the 620 iGPU. My monitor is hooked up to my YogaBook via an external hub. From the monitor to the hub I'm using a Displayport 1.2 cable. From the hub to the C930, I'm using a USB-C cable. When the computer goes to sleep, upon resuming, my external monitor is not displayed despite setting the Windows 10 settings to "duplicate', "extend" or "second screen only". Also, if I don't have the external monitor turned on before starting up the laptop, it will fail to detect a signal from the laptop/hub.


Any ideas as to how to resolve these issues?


Thank you for the pointers.
