Q: kernel_task 400% cpu when external display

Hi,

I have brand new 2,8 GHz i7 Macbook Pro Retina Mid 2015.

When I'm connected to external dell 4K UP3214q monitor through thunderbolt my computer slows down dramatically and heats up even in Safari or watching movies.

In activity monitor it shows more than 400% cpu usage on kernel_task.

Is it some bug in 10.10.4?

I paid more than 3000$ for computer and I cant use it with external monitor.

 

Please help.

 

Regards,

Durczynski

MacBook Pro with Retina display, OS X Yosemite (10.10.4)
