I was thinking about using my x1(flashed to 4800)for and outdoor showing at a barbecue at my house. I was thinking of just using a bedsheet and hooking up just basic stereo sound using an old reciever and my front mains. Has anyone tried this before and if so could you offer tips. I know ambient light is probably the biggest issue. I know I have seen pictures of people using the x1 outside, so I know it is possible.
