External Display not waking up from sleep or during boot.

2017-11-20, 14:18 PM

Greetings all,

 

1) I am using X1 Carbon 5th Gen with all the latest drivers and Windows updates.

2) I connect the laptop via it's Thunderbolt to an external LG 4K monitor's displayport.

3) However, the external monitor can't seem to wake up from sleep or during boot / restart or auto detects itself.

4) The only solution is to unplug the USB-C-Displayport cable everytime I need to connect to the external monitor. Once i plugged it in, the external monitor will then wake up.

5) Is there a way to make the external monitor to wake up from sleep or during boot up automatically without having the need to unplug/plug the cable everytime?

6) Appreciate any suggestions or solutions.

 

Moses

Same problem. I'm using X1 Yoga 2nd gen with latest drivers and Thinkvision X1 Monitor via USB-C cable directly. 

 

I need to turn off and on monitor everytime I boot and after PC goes to sleep. 

 

Any help would be greatly appreciated!! 

 

Thanks
