Recently our company purchase a bulk of x1-carbon and P27h-10 monitors. However we are expericing issues when we try to connect the laptop back to the monitor after some time. It does not wake up from the power saving mode. Even restarting the laptop does not solve this issue. We need to keep restarting multiple times and by chances it will be detected. This happens only with the x1-carbon laptops and we have no issues with other brand laptops like Dell. Just to note we have already update the firmware and drivers for the x1-carbon. The Lenovo on-site engineer have also replcace out display ports and motherboard of the notebook but the problem still exist till date.

Thank you for using the community forums.
Let's isolate the issue. Could you try to connect the monitor to another computer and check if the issue remains? If you have another monitor, try to connect it to your Thinkpad X1 Carbon and check if the same issue occurs.
Let us know how it goes.

We had tried using different laptop and connect to the P27h-10 monitor and i do not have this issue. We bought both the P and T series monitors both having the same issue. So to be clear it seems like the problem lies with the x1-carbon connection to the monitors. Also to note we tried using USB-C and HDMI. Both ways causing the same problem as well.
