I'm sure the solution is simple but I'm having difficulty finding a projector (doesn't have to be high spec, our budget is low) that can project from my Macbook Pro at a 720 or 1080 and then I will be filming the projection. I will be shooting with a Canon 5D MkII at 25fps. I've tried a few projectors and looking at the specs they project at a number of refresh rates but they all seem to create scanlines horizontally. So what refresh rates work with 25fps? 50hz I know is fine but I can't find a projector that does that rate at 720 or 1080 out of the macbook pro. Are multiples of 25 ok? 75hz, 100hz? Also can you recommend a low(ish) budget projector to do it?
