Laptop Lags When Connected To External Monitor

I have had my Thinkpad T480 for about 5 months now, and I connect it to an external monitor.  Whenever I shut down and restart, the computer does not read the monitor.  I have to unplug and reconnect each time, then it works fine.

 

Anyone have this problem?  Anyone have a solution?

Try doing a Restart (not Shutdown). If it recognizes the monitor you have the same problem I do. 

The bug is in Hiperboot assuming you are a Windows user. 

Turn off Fast Start in Power manager or use the Shutdown command from a CMD prompt not the Windows GUI.
