Multiple Monitor Display Isuse / Power Saving / X1 Carbon / Thinkpad USB-C dock 40A9 / ThinkVision

2019-05-14, 17:07 PM

Hi -

 

I have a new X1 Carbon Laptop with a USB-C Dock (40A9) and 2 ThinkVision monitors and Windows 10. All firmware is the latest version that I can find on the Lenovo site. Windows 10 is updated. Windows 10 detects all 3 monitors (laptop, 2 externals), but only 1 will show the desktop extended to it.

 

If we unplug one, the display extends fine. If we plug the second one in, the first one goes into Power Saving Mode and I can't get it to wake up and show the dispaly extended.

 

Both monitors are using MiniDisplayPort -> DisplayPort cables which connect to the hub directly. . It seems like there's a power issue, but I've set the settings on Windows 10 to "Never Sleep" - etc. I'm not sure why I can't get it off power saving mode.

 

Any ideas?

Thanks!
