I would like to see 4:3 and 16:9 aspect ratio screens. The reason I ask is because my projector is 4:3 native but do not know what a screen like that will look like. Can I calibrate a projector to display 16:9 widescreen format with a 4:3 projector? My dilemma is whether to keep the projector my company gave me or just purchase another one (with 16:9). I plan on purchasing a Dalite screen. There are so many options. In a 15'x11.5'x8' room with no windows, what screen sizes are good. I've heard from both Bob and Neil saying 96" or 100" will be good. I guess my question is, what are those dimensions for a 4:3 and 16:9? Thanks!!!
