Macbook Pro Display Disabled?
 

Hello all,

I need some help with an issue I'm running into. I'm using a MacBook Pro 2017 with Mojave installed. When I boot it up and have it docked into a Dell dock, I can get the laptop screen and two other external monitors working. However if I close the screen/lid, the two external monitors still work but if I reopen the lid, the laptop screen no longer works, unless I reboot it . Any ideas how to fix this?

Appreciate any support.

Carlos
