Go Big or Go Home – Make a 375-inch (or Larger) Image

There are big screens and then there are BIG screens.  This article is for those going BIG!  Churches, Concerts, Drive-in Movie Theaters, Parks, Art Installations, Sporting Events and more.  But just how do you project an image that big? The answer just might be edge blending, a large venue projector or both.

Projector screens are measured corner to corner, diagonally, just like a television.  Screens larger than 375” will often require the use of edge blending or a specialized large venue projector, rated between 7,000 and 10,000 lumens.

What is edge blending?

Edge blending combines multiple projectors, allowing you to move beyond the limitations of a single projector to create bright, massive, seamless, incredibly high-resolution displays.  When the audience believes the image comes from a single source you can consider the edge blending successful.

Large Venue Projectors

Some high-end projectors include a processor with the ability to blend multiple images seamlessly, while standard projectors may require presentation media software to accomplish a perfectly aligned and seamless image.

To edge blend, you will need two or more projectors with the same:

  • Resolution
  • Brightness
  • Throw Distance
  • Hours of Use and
  • Color Parameters or Temperature

In short, we recommend choosing projectors of the same brand and model as this offers much easier and more consistent image brightness and color when blending multiple images.

Begin with our article “Five Things to Consider When Picking a Projector”.  When you are ready an excellent source to find a large venue projector is Projector Central.  You may want to consider sticking with these trusted brands: Panasonic, Epson, Optoma, BenQ, ViewSonic and LG.

Presentation Media Software

If a high-end projector with built-in processor is out of your budget, you will want to consider the software option instead.

One of the most popular software options is called ProPresenter, by Renewed Vision.  ProPresenter is a cross-platform (Mac and Windows) presentation and production application for live events. It seamlessly displays lyrics, slides, and media, making high-quality live productions easy. It is an indispensable tool for worship gatherings, sporting events, conferences, trade shows, and studio broadcasts. ProPresenter operators control presentations on one screen, while dynamically presenting to an audience on one or more additional screens. Its quality is equally suitable for powering presentations in an environment for 100 people or 100,000.

It allows you to import, play and control videos, add effects, crop, scale and much more. In addition, these same effects and manipulations can also be used on recorded or live video sources.

ProPresenter was designed from the beginning to allow beginners to feel confident in running the software with only a few minutes of training and they make all training available online, via free video tutorials, you can access before you even purchase the software.
