Years ago, projectors were the easiest way to display large images, but flat-screens and LCD-based digital whiteboards now dominate conference rooms and workplaces. Today, however. the projector is staging a comeback.
If you haven’t looked at projector technology recently, you might be surprised at how it’s improved in quality. But can these improved features transfer to the conference room? Here’s what IT leaders should know about the various projectors available today.
Unlike regular projectors, short-throw projectors can display large images at a closer distance, generally between 3 to 8 feet away from a screen or surface. According to Epson’s projector guide, they are known for their ability reduce “shadows and eye glare.”
Short-throw projectors take this technology a step further. They display images at up to 4 feet. Both projector types can be installed on a wall, ceiling or table.
Projectors are defined by several different features, such as the technology they use to display images, the brightness of the resulting imaged and the proximity of the projector to the wall.

The distance required to display an image at a certain size is known as the “throw.” Epson’s positioning guide explains that the “projector position and the size of the image will depend upon your room configuration. Therefore, you will need to consider the throw distance and the projector features that will give you placement flexibility.”
Projectors predate modern day flat-screens. They are more closely associated with the cathode ray tube, says Bob Wudeck, senior director of business development for BenQ, a manufacturer of display technology.
“There are different ways people are using projectors. They are trying to make projectors more like smartphones,” he says.
Short throw projectors have some notable distinctions. For one, their ability to display images from shorter distances makes them easier to install in a variety of settings.

Ultra-short-throw projectors take the basic concept of the short throw projector even further. These projectors can display large images from a short distance. Epson notes that an 80-inch image can be generated from 50 centimeters (about 20 inches) away. Despite the distance, which can cause an unclear image, this type of projector keeps the quality clear and in focus.
Harkening back to earlier eras of computing, ultra-short-throw technology was the centerpiece for a type of interactive whiteboard that integrated touch input with a projector. In this arrangement, the projector was traditionally located above the whiteboard.
But in more recent years, the technology’s positioning has shifted, and it is now being sold in some markets as a high-end alternative to flat-screen televisions. Sold in a size roughly comparable to a video game console, these home theater-style projectors are placed on a TV stand near the wall, where they can display large, vibrant images well beyond a traditional flat-screen. At CES this year, Samsung showed off an 8K ultra-short-throw projector.
Ultra-short-throws can be useful in a business context because they work in cramped spaces, where it might be difficult to get a projector or large LCD screen assembled.
“Ultra-short-throw projectors are great if you’re in a huddle space where you don’t have six feet, you want to do a smaller projector and you need to do a 100-inch display,” Wudeck says. “The ultra-short-throw is a very easy way to do it, because you can mount it directly on the wall.” That said, Wudeck warns that the interactivity is not as robust as that of a multitouch touch screen.

The first modern digital projector was invented in 1984 by Gene Dolgoff. Since then, projector technology has evolved into multiple options, only some of which function like the old overhead projectors you might remember from the classroom.
The most common types include:
Regardless of the type of projector you choose, maintenance concerns should factor into your decision-making — particularly if it will be used in a busy conference room.

With each iteration of technology, new features are rolled out which purportedly make displays noticeably better. Recent smartphones, for example, have increased refresh rates and have gotten significantly brighter in recent years, a product of their use of active-matrix organic light-emitting diode (AMOLED) technology.
Conference room display technology works the same way. Each generation of flat-screens can display wider color ranges and resolutions than what might previously have been possible.
Projectors have also benefited from these new advancements. For example, LED and laser projectors can now display images at resolutions similar to that of modern televisions.
Wudeck says that most projectors built for an office environment are bright enough for indoor use; major deterrents are likely to be low-resolution screens with jagged edges. These imperfections are more noticeable with projectors because the number of pixels per inch is significantly lower than you might see on a smartphone or laptop. He suggests that a 1920x1080-pixel resolution is a reasonable floor for projector screens, with 4K being a preferable option.
“The two things that make the biggest difference in the meeting room are resolution and color accuracy,” Wudeck says. “There’s nothing more distracting than looking at a picture when the colors don’t look right.”

These days, it is possible to get a large, noninteractive flat-screen television for a few hundred dollars. Projectors tend to be more expensive, with some options selling at $2,000 or more. But these come with several advantages over a flat-screen, such as weight and size.
Projectors can work well in presentation mode, says Wudeck, though he warns that lasers and lamps must be positioned carefully so that the light source doesn’t hurt the speaker’s eyes.
This is important to keep in mind, as projectors may require adjustment to account for viewing angles and speaker positioning. Panasonic, a manufacturer of projectors, offers a calculator that can help you determine how to place a projector in a given room.

Ultimately, deciding between a projector or flat-screen comes down to your needs. If direct interactivity with the screen is your goal — if you’re hoping to use the monitor as a touch screen or interactive whiteboard — a flat-screen television or monitor may make more sense, as LCD and OLED screens have outpaced projectors on the multitouch technology front.
But if you want to display the largest possible image at the highest fidelity, short-throw and ultra-short-throw projectors are more beneficial, especially in smaller office settings. If you have a large conference room, consider an ultra-short-throw projector; if it’s a smaller space, try a traditional short-throw. Regardless of the type, today’s projectors are easier to install, cost-efficient and offer high-quality visuals.
