Seems very shady that the school would allow their employees to take these home. At least in my state, since they were purchased with tax dollars, they have to be auctioned off to the public.
Sorry OP, that's not a 1080p projector. It might accept 1080p input, but that is clearly a 4:3 projector. Probably 1024x768.
I still don't understand why people want projectors at home, the video quality is always awful.
