I was curious about how these projectors are able to project images up to these huge displays with such a crisp and high-quality definition. What resolutions are these films being filmed / played at? These are the questions I have lol
Thanks!

If you are wondering how the cinema projectors differ form the ones we use at home, this is how it differ.
The cinema projectors are much more brighter because they a have to project on a larger screen . They have better optics (lenses) . The resolution is mostly comparable, older one 2k -DCI and the newer ones 4k-DCI. A lot of home projectors are UHD which is very close to 4K DCI.
The most important difference is its ability to show vastly more colors and subtitle differences in tones than what a regular home projector is able to do. Also the source material is of much better quality.
Non ELI5 explanation :
Movie Theater films are mastered at 4k DCI resolution in a DCP-3 color space with very little compression. The projectors are designed to project this Image very faithfully.
Media for home are regularly created at UHD in rec 709 and is highly compressed. This is vastly inferior to the theater master. Unfortunately most of the sub $2000 k home projectors don’t even project this with the full color gamut. A few Epson 3 LCD 1080 projectors are an exception.
