Hi,
I am using MacBook Pro Mid 2015 with latest High Sierra Update 10.13.3.
What I have noticed is that when I connect my external display after a while (say 10 minutes) the kernel_task CPU utilization goes up and remains in the range of 450-500% till I disconnect the monitor.
Any solution to over come this issue?

All,
I got my MacBook Serviced and Cleaned. There was lot of dust accumulated near the side vents. After cleaning the MacBook is back at its best performance levels. No issues when connected to external monitor. The problem was solved when the fine dust was cleared. See the attached photo.
Now fans don't start, thus no kernel_task taking up lot of CPU. If you find this issue get the MacBook serviced and cleaned.
Had the same problem and ald updated with 10.13.4, but the problem still here.
