As far as hanging a fixed screen, you may want to consider a
hangman's mount. Would be easy to put up and down...and pretty forgiving.
You can make one yourself by just ripping a board on a 45 degree angle...mount one side to the back of the top of the frame and the other half to something hanging from your ceiling. If you decide to use a store-bought one (like in the link), then don't trust the "built-in leveling bubble"...they suck. Of course, something as simple as a couple of hooks hanging from the ceiling and eye bolts in the frame would also work (though it may tend to sway if a ceiling fan's on
).
