Good Afternoon all, My first post on the forum so please take it easy on me! I've searched for a few hours now for advice on vertically mounting a projector and throwing the image 90deg to the opposing wall - effectively opposite the top surface of the projector if the projector is mounted facing up. Assuming I have found a projector that has no cooling issues with being mounted this way, can anyone suggest a wall mount / mirror combo or offer any advise on either. I am aware that a perfectly flat, "first-surface" mirror will be required to minimise negative effects on picture quality but I have also seen a sort of 90deg prism setup that looks as though it mounts on to the lens surround itself... On Stackexchange of all places. Kind Regards, Z.
