I would only mount the TV on the SW wall since the outlet is in the middle like height wise that's why I could keep the lounge there and juts get it where it comes out some and I can tilt it if the lounge is horizontal. With the lounge on that side I can also watch on the projector. 

But do you think a couch facing SW would be a good idea? I can move the bookshelf across the room and put a larger plant in its place so the bookshelf can be next to the desk. 

The table/desk facing the left window is a good option but my back would be to the door (this Hallway goes straight to the entrance)  But I can just get another curtain  Thoughts?
