Many people think this is no problem, so they set it up this way so that 1.78 material fits the frame perfectly. On a 120" diagonal screen, the black bars would be about one inch each at the top and bottom. When it is set this way, all 1.85 movies will be shown with very tiny black bars at the top and bottom. The first option is to set the projector's lens so it just fills the 1.78 screen with a 1.78 image. There are two ways to watch 1.85 material on a 1.78 screen.

Once you get into 1080p home theater, many people like to experience music concerts in HD on the big screen. As examples, here are some movies that are either done in 1.78, or have been modified to 1.78 for Blu-ray.īut beyond some films and all of the HDTV broadcast programming that are done in 1.78, many live music concerts on Blu-ray are in 1.78.

So no matter what aspect ratio your screen is, you will always end up with black bars at the top and bottom of some material, and black pillars at the sides of other material. Here is a simple fact of life: Videos and movies are made in a variety of different aspect ratios. Many people prefer it because it matches the aspect ratio of a lot of movies being produced today. This is a wider format than standard 16:9. But if you are planning to use a projector and screen, you have another option, which is 2.4:1, commonly known as the Cinemascope format.
