From SOHO to Enterprise Applications, Business Projectors Create More
Opportunities
Keeping pace with increasing diversity in modern business types, a multitude
of design and functional innovations are available on business projectors.
Taking everything into consideration, three simple steps can enable home
office pros, small business owners, and even large corporations to find the
right projector to create more business opportunities.
Step One: Select a Projector Based on Conference Room Size and Projection
Brightness
An important consideration in choosing a projector for business information is
projection brightness. For typical small conference rooms of about 10 people,
we recommend a projector with 3,000–3,499 lumens of brightness to balance
energy savings and projection clarity. For medium meeting rooms for about 20
participants, the projector should produce 3,500–5,000 lumens to accommodate
more people and larger projection dimensions. An ultra-bright projector with
more than 5,000 lumens is ideal in larger conference rooms for over 40
attendees. This provides increased brightness and image clarity. In
addition—to support business presentations held in rooms where the lights are
on—we recommend raising the brightness requirement by 1,000 lumens.
Step Two:
Choose a Projector Based on Installation Requirements
In business, a projector may need to be moved into different conference
rooms—or even carried to client meetings. It is critical to choose the right
projector according to the specific needs of the business. In conference rooms
where the projector can be placed directly in front of the screen, a projector
with vertical keystone correction facilitates optimal image alignment. If a
small meeting room’s space constraints make it difficult to position the
projector in front of the screen, a projector model with both horizontal and
vertical keystone correction and side projection capability can ensure the
correct image aspect ratio from either the left or right side of the
screen.
Step Three: Choose a Projector to Meet Business Requirements
Today, a wide variety of projectors are available to meet the diverse needs of
modern businesses. Considering the needs for different business meetings,
wired connection models can satisfy the majority of projection requirements
used in a single space. If the projector often connects to smart devices for
projection sources, look for wireless transmission capability. For large
businesses with dedicated projectors in multiple conference rooms, business
projector models with LAN connectivity and remote management capabilities can
facilitate efficient management of multiple projectors.

Knowing the Specs to Choose the Ideal Business Projector
Choosing the right projector can help your business and its employees get more
done with less effort. On the flip side, using the wrong projector will not
only frustrate its
user but also slow down the progress of a meeting by dragging down efficiency
and decreasing productivity. Because of all this, the task of choosing the
right projector for your business is especially important. This article will
explain the terminology that is most commonly used in projector specifications
to ensure that your decision-making process goes smoothly.
Explaining the Terms
Projection Systems (Technology)
DLP
DLP projectors are projectors where the light produced by the light source
travels through a focus lens, passes through a spinning color wheel that
separates the color, and is then beamed onto a DMD (Digital Micromirror
Device) chip. Each microscopic mirror on the DMD chip then adjusts its angle
based on the digitized video signal stored in the chip’s memory so that the
light that is reflected off it produces the image that is projected. The color
produced by DLP projectors tends to be more accurate and doesn’t easily fade.
3LCD
3LCD projectors utilize LCD panels to modify the color of the light from the
light source based on the video signal, generating the image that is projected
onto the screen. The benefits of using 3LCD projectors are that their colors
are vivid and more saturated, while their disadvantages are that they usually
have weaker contrast levels, and their colors tend to fade.
Light Source
Laser
The advantages of using a laser light source include:
- Very high brightness
- Longer lifetime resulting in lower repair/maintenance costs
- Quick power on/off time
- Lower light/lumen depreciation so the color and brightness levels stay well preserved over time The disadvantage of using a laser light source is that the initial cost is higher than lamp light source.
Lamp
The advantages of using a mercury lamp as a light source include:
-
Low cost
-
Strong color performance
The disadvantages of using a mercury lamp as a light source include: -
Shorter light source life span: approximately 2,000 hours for an entry-level model, and 4,000– 6,000 hours for a high-end model
-
The image will gradually become darker and more yellow as the brightness, color saturation, and contrast levels deteriorate
-
Higher maintenance costs
Brightness
Lumen
Lumens are the units used to measure the total light output produced by a
light source in a given amount of time. The amount of light in an average
conference room is about 50 lux (lumen per square meter). Based on testing
the amount of light needed from a projector is about five times that of its
surrounding, or in the case of a normal conference room, 1,250 lux. The table
below lists the recommended brightness in lumens for a projector installed in
a 250-lux ambient light setting based on screen size.
Illuminance on the screen (Ambient light — 2501ux)
Screen Size (inch)| Recommendation for Projector Brightness (AL)
78| 2100 AL
92| 2900 AL
100| 3500 AL
120| 5000 AL
135| 6300 AL
150| 7700 AL
160| 8800 AL
180| 10000 AL
Image Quality
Contrast Ratio
The simplest way of measuring contrast is to measure the ratio between the
brightness of the light reflected from a solid white image to that of a solid
black image. This means that for a projector with a 5000:1 contrast ratio the
solid white image is 5000 times brighter than the solid black image. The
higher the contrast ratio, the more detailed the image is—no matter if you are
talking about numbers, text, graphics, pictures, or videos. Contrast allows us
to notice subtle differences in color and shadows, thus a higher contrast
ratio makes it easier for the viewer to see a greater number of details.
Aspect Ratio
Aspect ratio is the ratio between the width and height of the projected image.
For example, the aspect ratio for a Full HD image is 16:9. Traditional TV
shows broadcast at an aspect ratio of 4:3. This is roughly equivalent to a
square, but the vast majority of televisions currently transmit at the 16:9
aspect ratio of FHD. Projectors commonly use the following aspect ratios: 4:3
(XGA), 16:9 (FHD/4K), 16:10 (WXGA/WUXGA).
Resolution (4K / FHD / WUXGA / WXGA / XGA)
A projector’s resolution is defined as the number of horizontal pixels
multiplied by the number of vertical pixels. For example, the resolution for
Full HD video is 1920×1080. The larger the number of pixels an image has the
clearer the image becomes. The following are resolutions for various display
standards:
- XGA: 1024×768
- WXGA: 1280×800
- WUXGA: 1920×1200
- FHD: 1920×1080
- 4K: 3840 x 2160
Projection Distance
The principle behind projection distance is that the shorter the projection
distance, the greater the number of lenses needed; the higher the complexity
of the projector design, the lower the yield—all resulting in a higher price
for the projector. Below is a list of projector types, in terms of projection
distance, and their suitable settings:
- Normal: Conference rooms and classrooms
- Short Throw: Exhibition spaces, simulation space, small classrooms, and small conference rooms
- Ultra Short Throw: Interactive projection spaces and interactive classrooms
Optical
The sections below will help describe throw ratio, zoom ratio, lens shift, and
their differences.
Throw Ratio
Throw ratio is the distance from the projector lens to the screen divided by
the screen width. For a fixed screen width, the shorter the projection
distance, the smaller the throw ratio. This is the case for short throw and
ultra short throw projectors—and vice versa for longdistance projectors.
Zoom Ratio
If a projector is designed with a built-in zoom lens, it will be able to
adjust the size of its projected image from a fixed position without having to
move the projector. Zoom ratio is then defined as the ratio between the
width/length of the largest image the lens can produce from a given position
and the width/length of the smallest image the lens can produce from the same
position. This means that given a fixed image/screen size, the larger the zoom
ratio, the larger the range of distance the projector can be placed from the
screen. Thus, the larger the zoom ratio the more flexibility you will have in
terms of installation options. In this scenario, as seen in the image below,
the zoom ratio is equal to the Da divided by Db (where D is the distance
between the projector and the screen). Lens Shift
For most users it’s quite difficult to get the projected image to be perfectly
centered on the screen during the installation process. A lot of the time the
projected image will fall either above or to the side of the screen, while
trying to perfectly center the image on the screen solely by means of moving
or adjusting the projector itself hardly ever works. Because of all this, lens
shift is a must-have feature for projectors. Its vertical shift allows the
projector’s lens to shift in order to move the image up or down, while its
horizontal shift allows the lens to move the image left or right. Most
projectors feature hardware controls on the projector itself that allow users
to perform the lens shift function, while some high-end projectors allow you
to use the lens shift function via electronic controls or the remote control.
For example—if using the BenQ LK953ST projecting a 100-inch image—a vertical
shift has a range of 60% (60% of the height of the image), while the
horizontal shift has a range of 23% (23% of the image width).
Keystone (Vertical Keystone, 2D
Keystone, Auto Keystone)
When a projector is installed in a location/orientation that prevents it from
being properly aligned to the center of the screen the projected image will be
distorted into a trapezoid. This is called the keystone effect. For instance,
if the projector is installed above the screen and is tilted down when
projecting, the image will have a keystone effect along its vertical axis. If
the projector is even with the screen—but is off-center horizontally—the image
will have a keystone effect along the horizontal axis. The reason why this
happens is because the projected image is not properly projecting onto the
plane of the screen at the required 90-degree angle.
Need HORIZONTAL Keystone correction The following are descriptions of the
different type of keystone corrections available on projectors:
- Vertical Keystone: The most basic keystone correction. Currently 4K projectors only support vertical keystone because of limitations in their circuitry.
- 2D Keystone: Supports both vertical and horizontal keystone correction.
- Auto Keystone: High-end projectors feature auto keystone correction where a G-sensor is embedded into the projector allowing the projector to automatically correct for the keystone effect via a hard key or the projector’s OSD menu.
