How to enable display on Dell monitor connected to MacBook Pro when not charging?
I am happy to tell you that keeping it charging will not damage your MacBook in any way! There is also a way to do your requested way of streaming data to the monitor. You can use the amazing Apple TV. This is not only for TV's because you can stream to monitors, and your own TV! (which personally is amazing if you have a large flatscreen!) However I am not 100% sure this is compatible with all types of monitors or TV's so i would recommend just keeping it plugged in because like I said earlier that will not damage your computer. I hope this helped! The reason your having this problem is because monitors aren't computers. They don't have wifi, you can't connect them to anything wirelessly. Monitors don't have any form of computational power except for converting computer code to images which still requires being connected to a computer to work.
