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?
Regards,

MacBook Pro with Retina display, macOS High Sierra (10.13)
Tried a lot of stuff before - SMC, PRAM reset, offloading apps, new OS Install but useless after a while.
But this worked for me.
I opened and cleaned the MacbookPro (15" Mid 2015). There was dust accumulated in the fans.
For anyone reading this - please watch some videos on Youtube if have not done that before and intend to DIY like me.
After cleaning, kernel_task is not influenced anymore by external monitors and I can do simultaneous heavy tasks (coding IDEs, running servers) without any issues.
Thanks for the hint Kedar!
However, I wonder how does dust affect the kernel_task!
Had the same problem and ald updated with 10.13.4, but the problem still here.
