I don’t think you meant to reply to this post (which is mine) but I think you should repost with a thread heading.
My question (again) is I am watching a baseball game right now and can’t work as if I do, off goes the external monitor connected to the Macbook Pro, so am sure its a simple answer but have had it on so long, I forget how to turn it on and off.
Help, as I need to get to work. LOL.
