Put second monitor in full screen without toolbars
i know can press f11 open full screen view. , can see opens on second monitor if 1 connected. shift+f11 switch toggle second monitor "kind of full screen". it's not quite there because still has tool bars @ top , bottom. can click them collapse, they're not entirely hidden. how can rid of remains of except image on second monitor? works fine pressing f single monitor, can't work on second monitor. i'd keep lr on primary monitor , use different resolutions both monitors (laptop screen , external projector). only way know off turn on lights-out mode on it. hit l key. keep thin line around image unfortunately.
