While no real, additional source resolution is implied, upconversion from real video content has been proven to not only provide substantial additional image brightness from these millions of additional pixels but also additional realistic detail and subsequent improved clarity. Digital anamorphic upconversion is now a standard feature in all of the most popular high end 4K projectors to convert movies and other wide screen content to a higher resolution of 3840 x 2133 (16:9 projectors) for 33% more display pixels or 4096 x 2133 (17:9 projectors) for 25% more display pixels. UPCONVERTED CONTENT USING THE REPURPOSED BLACK PIXELS. When displayed on a 4K/4096 projector even with digital “zoom” settings there are 1,856,853 unused display pixels in those black bars. When displayed on a 4K/3840 UHD projector there are 2,150,400 unused display pixels in the black bars above and below the content. Consumer cinema-format 4K movies and streaming content is delivered using 3840 horizontal x 1600 vertical pixels to maintain its original 2.4:1 aspect ratio (ie 3840/1600=2.4). ORIGINAL CONTENT “LETTERBOXED” INSIDE UNUSED BLACK BAR DISPLAY PIXELS. How does anamorphic projection increase the brightness and detail of movies? The anamorphic big screen advantage means your projector can actually deliver higher detail than you’ll see in most commercial theaters and certainly higher than you can see with a flat panel TV.

But now today’s most popular projector models also include anamorphic upconversion modes for use with an external anamorphic lens to convert their full 4K performance into the larger 2.4:1 cinema format for the highest brightness and detail – all while still providing modes for watching 16:9 content.

This content is meant and created to be the largest experience in your theater but on a flat panel TV or 16:9 projection system it is actually displayed as the smallest experience with the lowest performance because millions of display pixels are turned off to create black bars (yes, even with “ lens memory zooming“). Over 80% of the most popular movies are made in the standard commercial cinema 2.4:1 aspect ratio and even today’s streaming shows are migrating to this format. Over 80% of the most popular movies since 1972 are made in the 2.4:1 cinema aspect ratio – much wider than 4K/UHDTV – and even streaming content is rapidly evolving toward this format.
