What considerations do you need to take into account when choosing the right projector for a home or business installation?

First, how much detail do you need in the images that are being displayed?

After determining the answer to that, next, what is the aspect ratio needed for the content that will be viewed (i.e. movies, sports, PowerPoint presentations, etc.). For business and education setups, you may have to consider a variety of possible scenarios from movie viewing to PowerPoint presentations, so you might need a more versatile projector. Whereas a home installation might be primarily for movie viewing, which could be more straightforward.

Multimedia content typically uses a 16:9 aspect ratio and typical PowerPoint slides are often in a 4:3 t0 16:9 format. 

Business/education space you might want to consider using SVGA, XGA, WXGA, WUXGA, 1080p and 4K.

You’ll also want to consider the viewing setup. How close will the viewer be to the image and how large will the image be? Viewing distance and screen size have a significant factor in resolution.
For example, when you sit closer or enlarge a Full HD image, you can see the pixels that make up the picture. Since 4K Ultra HD has four times more resolution than Full HD it would be nearly impossible to see the pixels at the same viewing distance.
