A 2.4:1 Cinema Format Screen
First and foremost, you need a projector screen that matches the aspect ratio of the content you plan to watch. For cinephiles, that means a 2.4:1 screen. Because most of the content you’ll be watching in your home theater will be movies and streaming television, you’ll benefit most from this screen size.
You may wonder what this means for 16:9 content, like sports and news. If you also plan to use your home theater to watch the Cubs or keep up with local headlines, you could invest in two motorized retractable projector screens if you want to avoid black sidebars for the occasional 16:9 content.
Plus, when paired with a projector that features an anamorphic lens, you can automatically move between aspect ratios with zero inconvenience.
A 4K Projector with an External Anamorphic Lens
Speaking of an anamorphic lens, what is it? And why do you need one to create a true 4K UltraWide cinema experience? First, “anamorphic” simply refers to the cinematic format technique of shooting a widescreen picture. An external anamorphic lens externally attaches to your 4K projector to stretch or compress an image so that it displays properly based on aspect ratio.
