Maybe not an age-old question, but one that people who need to put on effective presentations need to answer “Why should I choose projection over flat panel displays?” There are eight (count them, eight!) important considerations—purpose, audience sizes and positions, image sizes, visibility, affordability, durability, portability, and convenient setup, removal, and connectivity— that compel presenters or professional installers to decide that projectors will serve them better than a flat panel display.
First off, what is the purpose of the presentation? Is the material highly detailed? Are images critical to the presentation? Since projectors ensure the very best displays of detailed images and text, presenters are assured their audiences will receive the presentation in its best possible light.
Whether you’re presenting to an audience in a classroom or an auditorium, the audience size and how they’ll be viewing the presentation influences the type of display a presenter chooses. Projectors allow for more flexible placement than those of flat panels as well as a variable screen size so an audience of one to one hundred can easily be accommodated by the same projector.
Another consideration is image size for determining the right solution. If images require a 40- to 90-inch diagonal, then a flat panel will suffice. However, if the images need to be on a 100-inch diagonal screen or appear on curved surfaces, projection is preferable.
You may have noticed this kind of use in retail environments as projected images are perfect for eye-grabbing digital signage. For example, a retailer wanting to stretch an image 125 feet along an extensive back wall can install a projector in the ceiling that shines the image downward upon the wall. A comparable flat panel setup would require an extensive setup – and a higher budget.
Flat panels’ glass creates glare absent in projected images. Another advantage projectors provide are an enhanced fill factor, resulting in smoother images. The better visibility inherent in projected images captures and holds audience members’ attention and ensures memorability. Additionally, flat panels can suffer from image burn-in or retention, while projectors are unhampered by that issue.
Affordability and durability
Money still does not grow on trees – therefore whether an option is affordable is always a consideration for any application. On an inch-by-inch comparison, projectors can give you more image per dollar, especially with their flexibility to throw to screens of more than 100 inches. And as far as durability—projectors typically outlast flat screens.
Portability and removability
A system’s portability factors in, too. Despite the advent of thinner flat panel displays in the last few years, shipping and logistics are more complicated for flat panel displays. Transporting large flat panel displays and their associated stands and mounts, whether to in-house, in-town, or out-of-town venues, is challenging and expensive. Oppositely, presenters need only carry a projector and a screen to present stunning images to audiences at any site.
Easy setup and removal
Just like with a party, presenters are often tasked with setting up and removing their display systems. Projectors and any accompanying screens offer convenient setup, disassembly, and removal, especially compared to flat panel alternatives.
Unless assembling giant Lego-like structures is a hobby, flat panel setups can be significantly more effort to hang and easily devise a useful connectivity. Projectors’ connections may be extended through suspended ceilings. In contrast, hanging, taking down, and removing flat panels is a hassle and improving their connectivity through supporting walls is difficult.
As you can see, when you add it up, the advantages projectors provide for presenters are numerous—better outcomes for purposes, more flexibility surrounding audience sizes and positions, larger and more detailed images, superior visibility, greater affordability and durability, easier portability, and more convenient setup and removal alongside better connectivity.
