Have Aspire E15 E5-575G-53VG with Windows 10 and have connected an external monitor on which to edit my photos. I have chosen to only display on 2nd monitor and selected for power to stay on when closing lid.  But, when I reopen lid my laptop screen powers up and laptop and external monitors are now in duplicate mode changing the view on my second monitor. How do I keep laptop monitor from powering up and changing view on external monitor when I open laptop lid?
