Ok ladies, I have 2 monitors and somehow have miss placed one charging cable for both monitors and the charging cables are not interchangeable!! Ugh! So I'm in need of a new monitor cause I cant find the cables ANYWHERE! Am thinking of getting a wifi one but am concerned they could be hacked and strangers could see my child's room. Am I being paranoid or is this a thing that could and does happen? Thoughts?
