I waited until it got dark, hung up and “old school” screen, added a bungee to the bottom of it and started projecting.
One of the controls lets me adjust the key enough to make it square, I hooked up my Boise Mini with a 3.5mm jack and started watching it. I ended up scaling it down to 75% of the size to get it to fit on my 52 inch screen and it worked great.
It doesn’t work in day light (not bright enough), but at night I was happy with it. I watch Thor using Apple TV and Netflix... worked great for the price!
