Overcoming Security Threats: In-Room Collaboration Technology

by | Apr 13, 2023 | Uncategorized, Wireless Collaboration

Wireless Security Layers

With the increase in hybrid collaboration following the pandemic, cybersecurity is at the forefront of everyone’s mind, especially in office meeting spaces and conference rooms with a great amount of traffic throughout the day – team members and guests included. IT and maintenance departments are incredibly precise with the hardware they are installing, focusing heavily on certifications and the way in which certain products handle these cybersecurity risks – in some cases, even gluing the USB ports of a government-issued laptop to manually prevent any plug-ins.

Wireless display technology presents many security risks, and in order to provide protection against any threats, there are three layers of security that are typical (and industry standard).

1. Connection Level

This involves the user’s laptop connecting to the closest access point and authenticating itself to the network (representing the standard set of security protocols WPA, 802.1X, WEP, etc.).

2. Session

The session involves the transmission of data – searching out, sending an email, connecting to a wireless printer, and much more. When a user transmits their data from a laptop to an access point, they are in an active session – the data is encrypted.

3. On-Screen

The on-screen layer involves a display pin that needs to be entered, requiring someone to be physically present in order to connect.

Network Security

Along with these three layers of security, ScreenBeam adds additional protection in the architecture of the device itself, providing an internal network for employees and an external network for guests, with a firewall in between. In your conference room, users with Apple devices can connect to the access point and use AirPlay to discover ScreenBeam as a display point over the network infrastructure – this applies exclusively to company employees. For those with Windows 10/11 devices, users may connect to ScreenBeam using P2P mode. On the other hand, guests may use WiFi tools with ScreenBeam an access point, without ever interacting with the internal network. If they require Internet access, they can gain this permission through WLAN1.

When utilizing ScreenBeam, users must authenticate themselves, as anything shared is encrypted. With other similar technology, you must choose between putting a device on the internal network (which guests cannot use) or putting a device on the guest network, which requires every employee to also switch to the guest network. ScreenBeam is connected to both the internal network and the external network at the same time, so you can connect securely to both networks, without ever exposing your internal network to guests, since their access is directly connected to the display.

Additionally, when faced with guests that require a connection to the network, other similar devices would likely opt to provide guests with access to the internal network, therefore punching a hole in the firewall, which is not the most secure choice. With ScreenBeam, there is no connection between the local WiFi and Ethernet, which prevents access to the wired Ethernet, even if someone were able to hack into the local WiFi.

When it comes to in-room collaboration security, there’s much more to the product than most people realize.

With any questions or to learn more about ScreenBeam’s innovative solutions, I encourage you to contact me or reach out over on LinkedIn.

Behind the Panel: Navigating Direct View LED Mounts

by | Apr 11, 2023 | Uncategorized

We are back again – this time talking about the world of Direct View LED mounts. First, let’s take a brief look at Direct View LED as a solution:

Direct View LED (DVLED) is a technology that has existed for some time, but the last five to seven years has seen an explosion in the amount of manufacturers that are producing DVLED technology. In its most basic description, DVLED is a display consisting of several light-emitting diodes (LEDs) mounted on a circuit board, creating each panel. These panels are then configured into a larger, finished display. The biggest draw to these is you can get a much larger overall display than traditional LED displays, which usually top out around 100” diagonal. This gives you much greater flexibility to create larger display sizes, and not be limited to the traditional shape of normal displays. They can be pyramids, curved, columns… really the sky is the limit. These displays are also much brighter than traditional LED. Take the TV in your home, more than likely that will be around 300 nits in brightness. Professional digital signage displays are usually in the 500-700 nits range. DVLED are very bright, most times in a range of 4,000-10,000 nits, and because there is no glass, (hence the term, “Direct View”), they will not have glare, as well as offering much broader viewing angles.

Assessing the DVLED Install Needs

Chief digital signage solutionsThe first step in the process is assessing the install site. The integrator will have to do a thorough site survey, to make sure the solution will work. Making sure they have adequate access to power, and ensuring that the wall or structure that the display is being mounted to is secure and strong enough to support it. Once you have this done, you can work on designing and planning your wall layout and structure. Most manufacturers offer assistance in design for the mounting solution. Our partners at Legrand have really simplified the process with a great Online Configuration Tool to help put your display together. They offer many in-stock solutions for the major DVLED brands. If your DVLED isn’t available in one of their preconfigured varieties, they offer custom solutions as well.

Selecting a DVLED Mount Solution

Now, back to the mounts. The first question that I am often asked, is why a customer would choose third party mounts when the DVLED manufacturer has mounts that are made for their own solution. Great question! The answer is simple:

  • DISPLAY manufacturers primary focus is on developing and manufacturing DISPLAYS.
  • MOUNT manufacturers primary focus is on developing and manufacturing MOUNTS.

Although the DVLED manufacturers’ mounting solutions will fit, they will more than likely not work as well as mounts made by a mount manufacturer. Usually, the DVLED manufacturer has a mounting solution that is a pretty basic, perhaps a simple frame with some brackets. Third party mounts are designed with installers in mind. They will be set up for easier installation because they give you the ability to make micro-adjustments after they are mounted. For installers, having the ability to make x-y-z axis adjustments help ensure a perfectly planar video wall. They are usually a much more robust mount all together, with more features that produce a better finished product, and also have the installer in mind by making installation quicker, more efficient, and allowing for easier access when servicing post-install.

To draw an everyday life comparison, think about buying a car. When you purchase a car, often times the dealer would throw in floor mats for your car. The floor mats were OK, they matched the color of the interior, and would keep some dirt and grime off the floor of the car. But you could also go buy a set of floor mats that were made by a company that does nothing but make car accessories, composed of heavier duty material, laser machined to exactly fit in your vehicle, and would keep EVERYTHING off the floor of your vehicle. Wow, after writing that, I really think I need new floor mats. Anyways, this is why I would look to a mount manufacturer to make DVLED mount solutions, it is what they do every day!

I also know there is a whole segment of resellers out there who are relatively new to this space, and Exertis Almo has you covered there as well.

Exertis Almo Labor Project Support

Whether this is your first DVLED install or you are attempting something cutting-edge, like a curved wall, Exertis Almo has a services team that can professionally install that solution for you. Our team has a wealth of knowledge and experience in DVLED installation and commissioning. Find out more at https://www.ExertisAlmo.com/install.

That does it for me, catch you next time… behind the panel.

BUT, Did You Train Them?

by | Apr 6, 2023 | Uncategorized

Love for Learning

Our industry is comprised of remarkably brilliant minds and innovative thinkers from all different backgrounds, and of various experience levels. Being in this industry, the love for learning is a prerequisite, in my opinion, as the learning never stops! There’s endless and ever-changing information to consider, leaving no choice but to keep up if you want to thrive. In my experience throughout the past four years in Pro AV, I’ve witnessed or been part of countless changes. Some small and subtle, others very significant, even life changing. So, it’s safe to say that being part of Pro AV requires you to adapt and maintain flexibility while striving to provide the best solutions to the masses.

Arguably the most important aspect of our industry is the end user, the common public, the small to large business owner, and the like. This is where all the effort and main impression has the greatest impact. They, however, do not need to keep up with the rapid changes of all the technicalities involved. This is what they rely on us for, and the very reason we are able to stand out in a league of our own. As manufacturers, distributors, and integrators, it is in our best interest to provide the most seamless and enjoyable experience to the end user. Sometimes this means entertainment and pleasure, other times productivity and efficiency, but it always means satisfaction. As the professionals making the recommendations, innovations and installations, we need to stay as educated as possible.

How we stay up-do-date, and in turn, implement that knowledge out in the field, greatly affects the satisfaction of those investing in, and using our products and services. The level of satisfaction may create career long repeat business, or may alternately cause the decline or stagnation we all work to avoid. Not all installations or solutions are equal in terms on complexity or technicalities, but they are all equally relevant. A full concert hall with all the sound equipment, proper sound distribution and seating design, lighting, and staging, etc. is as important to the venue, audience, and performers as a simple meeting room or huddle room is to a small business and it’s attendees. The education and training, or even experience required by the installation crew is certainly much more involved from one to the other, but it is totally necessary in both examples. Knowing what to install and how to install it – given the environment, budget and desired experience – can be, and in many instances is, more involved than most would expect.

Industry Expertise

Leaving projects unfinished, or partially in the hands of the client/customer/end user as a responsibility to perform, is proving more and more to be detrimental to the integrators success. I’ve seen and heard of more examples than I’d like to admit of: “The customer is going to do it themselves,” “This was just a box sale,” and “They have techs on staff that can handle it.”  When we, in the industry from a distribution standpoint, hear this, what we truly hear is, “I don’t care if my customer is satisfied with the outcome.” This may come across as harsh, but the proof is out there, and it won’t take much effort for us to collectively clean it up find ways to assure every project is done right, every time.  Most manufacturers offer all the training you could possibly need, free of charge, to gain the knowledge to properly install and get the most out of the features their products offer. Many offer training for beyond what’s required to know, and can be utilized to gain certifications or credits to maintain certifications. Some require that you become certified prior to gaining access to purchase and resell the products.

One example is the Barco ClickShare line of product and the features it has to offer the end user. ClickShare has evolved considerably throughout the recent years. Most know it as a simple collaboration device for which meeting presenters share content onto a display or projection image from their laptop or other portable device through a USB button or app. While this is still true, the features and benefits now offered by the product line is far more robust. Barco’s XSM Cloud portal gives users the ability to monitor, schedule, control, update, load simple digital signage content, and more, all at no charge! The most commonly missed perk Barco offers is the free upgrade from a 1 year to a 5 year SmartCare warranty on any ClickShare unit when registered to the XMS Cloud portal within 6 months of purchase. It goes without saying that if the device isn’t even being registered on the platform properly, the available features are certainly not being used to their full potential, if at all. Minimal required trainings are the effort to prevent such misuse or lack of satisfaction, but until we all take the end result more seriously, these sometimes fall short and become just that; bare minimum requirements.

Customer-Driven Business Growth

Barco offers extensive and vast training on their website, all free of charge, so that everyone can get the most out of their product. As customer-driven businesses, the message we want to get out is that this – Customer satisfaction all begins with the knowledge and effort we put forth on each and every project. Know your products and how the end user will benefit most from the uses of them. Then, make sure they get set up and installed properly! Maybe your customers overlooked activating the SmartCare warranty for their ClickShare units? Don’t worry, they can still activate their SmartCare package on existing C5/ C10/ CX-20/ CX-30/ CX-50 devices from March 1st to June 30th, 2023.

Another offer that many times goes overlooked is Click2Sync. Do you struggle to create quality content for your website and social channels? Do you lack the time, skills or ideas to continuously bring out content that generates traffic and leads? Then Barco’s Click2Sync program is the perfect fit for you. Click2Sync is our new program for all ClickShare Connect! resellers that offers an easy and automated way to publish engaging ClickShare content on your website and social channels. It’s free and completely painless, thanks to a simple syndication plug-in on your website.

E4 Experience Blog #2: Expansive Services Offering

by | Apr 5, 2023 | E4 Experience, News, Uncategorized

This blog is reposted with permission from Commercial Integrator.   Author: Dan Ferrisi

Rob Voorhees explores Exertis Almo services and how they benefit integrators, as well as his passion for diversity, equity and inclusion.

During this month’s E4 Experience, Commercial Integrator had a chance to learn more about Exertis Almo’s services offering. We could have no better guide than Rob Voorhees, CTS, CTP, CTNS, DSCE, business development manager with Exertis Almo. After all, apart from overseeing the HARMAN vendor relationship, Voorhees manages the connectivity portion of Exertis Almo’s audiovisual services. During an expansive half-hour discussion with CI, Voorhees touches on Exertis Almo’s recent acquisition of Caddrillion Engineering & Drafting, LLC, as well as how the market-enablement company commits itself to lowering integrators’ barrier to entry for moving into services.

Entry into Exertis Almo Services

Voorhees starts the conversation with reflections on his arrival at Almo more than six years ago. Services were, in fact, his entry point into the organization, and he describes his initial impressions as pleasantly surprising. “At a lot of distributors and integrators, the term ‘one-stop shop’ gets thrown around very, very loosely,” Voorhees acknowledges. “One of the comments I made very early on in my career here,” he recalls, “was this: ‘This worldwide distributor really talks the talk and walks the walk.’”

In particular, Almo’s service mission — Voorhees summarized it as expanding integrators’ reach without increasing their overhead — impressed him. “It’s all about you knowing that you can fulfill a project or customer need without having to hire somebody new…without having to train somebody and dedicate those resources,” he adds.

When industry observers look at today’s Exertis Almo, they see a market-enablement company whose services portfolio is remarkably broad. Indeed, the organization’s offerings range from design and blueprinting all the way to DSP programming.

Voorhees, however, calls back to the foundational three Exertis Almo service offerings: labor, content creation and connectivity. Over time, the company presciently expanded on that foundation, with Exertis Almo responding, in real time, to emerging customer needs and partners’ desire to fulfill them.

Stepping into the Connectivity Arena

Right now, for example, the organization is leaning into its already-available cybersecurity services. As it is, Voorhees observes, some integrators are reluctant even to step into the connectivity arena because they are unfamiliar with the intricacies of bandwidth, streaming, etc. “Cybersecurity takes that to a multiplier of 10,” he notes. “It’s an even more difficult conversation.” But that’s precisely why integrators would want Exertis Almo as a service partner and consultative advisor.

As noted, Voorhees leads the connectivity portion of Exertis Almo services, and he shares some insights into it. “Our connectivity services allow us to partner and provide services from all the major ISPs in the country,” he explains. Indeed, Voorhees cites Comcast and AT&T as just two examples. Laying out an opportunity for recurring commission, he continues, “We allow our partners to provide those services to customers.”

One might think that dealing with ISPs falls outside integration businesses’ scope, but that would be wrong. After all, having sufficient network bandwidth is the single biggest key to a successful AV-over-IP deployment. “That’s why Exertis Almo got involved in something like connectivity services,” Voorhees states. “Because we saw where the industry was going.”

Caddrillion Acquisition Boosts Exertis Almo Services

In response to CI inquiring about Exertis Almo’s acquisition of Caddrillion, Voorhees explains that the organizations, in fact, had partnered for a couple years. Specifically, Caddrillion was a trusted resource for Exertis Almo with respect to systems design and engineering services. With expertise spanning systems design, systems engineering, project blueprinting, systems programming (e.g., AMX, BSS, Crestron, Extron) and remote programming, Caddrillion quickly proved a valuable partner for the market-enablement company.

“Over the time of building the partnership with them, [we determined] it might make sense for both parties to bring this in house,” Voorhees relates. The acquisition went into effect this past January 1.

It was a smart move for Exertis Almo, as it bolstered its services offering in the most impactful way. “AV design services have been a huge need just over the last year alone,” Voorhees declares. “That’s why [we’ve filled] that void in house now.” Moreover, he heaps praise on Caddrillion CEO Justin Gregory and his team, underlining once again their strength in engineering, drafting and programming. “They have just done a phenomenal job for our customers,” Voorhees enthuses.

Filling the Gaps

It’s clear that, in building its services offering, Exertis Almo is committed to filling the gaps in AV projects. Equally, however, the organization seeks to lower integrators’ barrier to entry so they can seize on service-oriented business opportunities. Voorhees remarks that today’s commercial AV industry is all about selling an experience. “And I consider [selling] services a big piece of that,” he declares.

But Voorhees remains mindful that not everyone natively “speaks the language” of services, nor are services everyone’s core competency. “[That’s why] any call or one-on-one meeting that I have with a partner to discuss ISP services — or anything else, for that matter — it’s all about going in to make it not as attractive as possible, but, instead, as simple as possible,” he stresses.

And Exertis Almo’s guidance frequently produces revelatory moments for partners. For example, Voorhees cites integrator conversations pertaining to his role with Exertis Almo’s connectivity services. He recalls integrators attesting that they frequently recommended internet-service suppliers but otherwise were uninvolved. However, when integrators learn about facilitating connectivity services through Exertis Almo and earning a commission, he says, “It’s like you’re reintroducing the wheel to them.”

This education about available opportunities frequently takes place during what Voorhees refers to as “discovery calls.” These conversations with integrator partners — as well as, sometimes, with end users — are incredibly useful for teasing out customer needs and elucidating the reasoning behind recommendations. “[It’s] not just about signing somebody up for something,” he declares, expressing a business integrity that is refreshing.

Embracing DEI

As passionate as Voorhees is about Exertis Almo services and serving partners well, he has equal passion for DEI. Part of it stems from having a teenage daughter on the autism spectrum. He states firmly that he wants to ensure his daughter never faces any barriers to entry as she pursues her dreams.

“Awareness and education are key,” Voorhees opines, crediting Exertis Almo as an organization that’s truly enlightened on diversity issues. “Getting to work for a company that addresses not just neurodiversity but also diversity and inclusion of all kinds is very comforting not only as an employee of that company but also as a parent,” he says. Although too modest to describe himself as a leader, Voorhees is an expositor of the message; he’s an active member of the AVIXA Diversity Council.

“It’s very, very powerful to feel comfortable and be happy as yourself,” Voorhees declares. Thus, it’s incumbent on AV industry organizations to proactively discuss and address these issues — not sweep them under the rug — and recognize that even small accommodations (e.g., noise-canceling headphones) can be transformative in empowering team members to deliver their very best. “More attention to little details is the key,” he advises.

Clearly, Exertis Almo pays attention to all the details of both its services and its inclusive company culture. And with powerful voices like Voorhees’ helping show the way, the market-enablement company’s future looks brighter than ever.

Breaking Down DVLED part 2 – Cabinets & Modules & Panels, Oh My!!!

Part 2: Cabinets and Modules and Panels, Oh My!!!

Topic: The anatomy of a DVLED video wall.

I didn’t sell DVLED video walls for a long time because I didn’t understand how to talk to customers about it.

My first formal training on DVLED was well over 10 years ago. What I remember most is how utterly confused I was walking away. It was a brand-new technology that was very expensive and promised to be the next wave in display technology. My expertise up to that point rested squarely within the confines of projectors and large flat panel LCD displays (LFD). I was comfortable in that world. I felt safe there! I certainly didn’t have the time to learn about a new technology that had hardly gotten off the ground floor.

Fast-forward to 2023 and DVLED is now KING of large format. If I’m not offering DLVED, I’m going to be left in the dust by my competition, and so are you! The good news is that DVLED is quite simple once you grasp a few simple concepts.

Whether you are a grizzled industry vet or a bright green newbie to the AV industry, my goal is to attempt to simplify the anatomy of a DVLED video wall and, hopefully, have you walk away with enough knowledge and tools to be semi-dangerous. If not dangerous, you should at least be able to carry a conversation with a prospective customer that is in the market for one of these exciting new video walls.

So, what is DVLED and how is it different?

Let’s start with the name! DVLED stands for Direct View Light Emitting Diode. You can google light emitting diode for technical information if you wish. For the purposes of this discussion, an LED is a tiny dot that lights up red, green ,and blue. When you put hundreds of thousands or millions of them together, they make a great, big, bright, colorful image.

direct view LED illustation

What is a Pixel Pitch?

In the world of projectors and LFD’s, we talk a lot about resolution (720p, 1080p, 4K, UXGA, etc.). From 30,000 feet, this tells us a lot about how well defined our picture will be. Basically, the higher the resolution, the more dots or “pixels” that make up the image. The more dots you have in the same relative area, the better the picture.

Pixel Pitch indicates how close together the dots will be. For example, an LED wall with a pixel pitch of 10 means there will be 10mm from center-to-center from one dot to the next. A pixel pitch of 2.5 is 2.5mm between dots and so on. As of this moment in 2023, many DVLED manufacturers are offering pixel pitches as “fine” as 0.7mm. To give you a point of reference, a 100 inch, 4K traditional LCD TV will give you an approximate pixel pitch of .45mm.

But I digress. The title of this blog is Modules and Cabinets and Panels, Oh My!!! So, what are these three things? Here is a simple formula to help:

Modules + Cabinet = Panel

Modules are the square or rectangular sections of LED’s that make up the picture and are generally affixed to the face of the cabinet with magnets. The cabinet is the square or rectangular chassis that houses the electronics and provides structure to the wall. Each panel (modules + cabinet) is like a big, expensive Lego. The cabinet is the base-plate and the modules are the bricks. They can be linked together to form any size or shape. Just add your imagination and some modern video scaling technology.

I sincerely hope this has information has helped you to understand the basic makeup of a DVLED video wall. Exertis-Almo offers a wide range of DVLED brands and I am the Business Development Manager for Absen USA, a world-class, leading manufacturer of DVLED video walls that has solutions for virtually any application. Feel free to drop me a note on LinkedIn or come out to see us at one of our upcoming E4 shows.

Edition 4 of “This May Be a Dumb Question, but…”

by | Mar 30, 2023 | Professional Development, Projectors, Uncategorized

This Blog Series is written by Exertis Almo's Business Development Managers: 
Ashley Nichols, CTS, DSCE, and John Borns, CTS, DSCE.

Welcome to our 4th and final issue focusing on projection topics. The most commonly asked questions we receive to have do with determining screen size, throw ratio, and brightness. We’re going to attempt to tackle those here today. To get here, we first wanted to make sure that you were knowledgeable enough to be dangerous when it comes to picking out screens and determining which TYPE of projector you need. If you’re coming in late on this, see our previous posts – edition 2 or edition 3.  WARNING: This may take a teensy bit of math, so get out your scratch paper!

FIRST UP: We need to understand aspect ratio.(1)

Simply put, aspect ratio is the relationship between the width and the height of a screen. It’s critical to know this so that we can ensure that the shape of projected image fits neatly within the screen. Every projector has a native aspect ratio, so ideally, you can pair a screen and projector with this information. Fortunately, this isn’t too much of a challenge, as MOST modern professional projectors can be programmed to support all sorts of aspect ratios. Why is this? Basically, the projector needs to be able to support anything you plug into it (computers, Blu-rays, you name it). Additionally, projectors don’t have the same lifespan as screens, so it’s very likely that you will need to match a new projector to an old screen. If someone took down the old projector and punted it into the sea before you had chance to know what it was, you can confidently install a new projector and trust it can adapt to the screen. Below are some common aspect ratios, and more specifically, the most common aspect ratios you will see in projection are 16:9, 16:10, and occasionally still a 4:3. The others are more commonly seen in LCD’s, gaming monitors, IMAX, etc., so we will ignore them for now.

ASPECT RATIO POSSIBLE RESOLUTIONS OTHER FORMS YOU WILL SEE
32:9 3840×1080, 5120×1440, 7680×2160 DFHD, DQHD, 32:9, DUHD
21:9 2560×1080, 3440×1440, 3840X1600, 5120×2160 21:9 Ultrawide
16:9 1280×720, 1366×768, 1600×900, 1920×1080, 2560×1440, 3840×2160, 5120×2880, 7680×4320 HD, FHD, 4K UHD, 8K UHD
16:10 1280×800, 1920×1200, 2560×1600 WUXGA, WXGA, WQXGA
4:3 1400×1050, 1440×1080, 1600×1200, 1920X1440, 2048X1536 XGA, SDTV

*Note: ‘other forms’ does not encompass all possibilities, just some of the most common forms

To calculate Aspect ratio when you aren’t sure what you have, the formula is Width divided by Height (W/H=AR). For example, pretend you have a screen that you measure and it is 125” wide by 70” high. 125” divided by 70” is 1.777. BEFORE you say, “Ashley, that is NOT on this list of aspect ratios!”— here is a handy tool to convert to nomenclature that is more common:

ASPECT RATIO ALSO ASPECT RATIO
16:9 1.78:1
16:10 1.6:1
4:3 1.33:1
21:9 2.33:1

These calculations MEAN the same thing: for every 16 units wide, there are 9 units high, or for every 1.777 units wide, there is 1 unit high. If you’re using an old fashioned calculator on your desk instead of some of the calculation tools out there on the World Wide Web, then you will see these decimals and can easily convert over to the more commonly used terms on the left.

SECOND UP: Throw ratio.(2)

Why do you need this? Well, if the aspect ratio is making sure you have the right shape of screen, the throw ratio will help make sure you have the right lens on the projector in relation to where you are mounting it, so that your image fills the screen to your liking. To calculate the throw ratio, you divide the distance from the projector by the width of the screen (D/W=TR). For example, you have 10.42 ft wide screen and you are mounting this bad boy 15ft away, you take 15ft/10.42ft= 1.439. Your throw ratio is 1.44:1, and you find the lens that fits that.

An important reminder is to make sure that you convert feet to inches (or vice versa) when doing your calculations. I’m commonly ask to recommend a screen for 125” wide screen that’s being mounted 15’ away. It would not look great for me to recommend a 1875:1 lens here – which is what you get if you don’t convert 15 feet into 180 inches. More commonly, I get requests such as, “I want to use XYZ projector, I have 164-inch diagonal screen and am mounting this 15ft away: which lens do I need?” I don’t know the width, but I do know the diagonal, so I can either ask for the width to be exact, or I can head over to this tool: http://screen-size.info/, pick out the Aspect Ratio, and find the width. If they give you another bit of info, like the height, then you can dig in the recesses of your brain and use the Pythagorean Theorem to manually calculate the width, but around here, we work smarter, not harder, so feel free to use the cheater tool.

LAST, not least (& probably the most difficult to calculate): How bright do I need my projector to be?

Why do I say this is harder to calculate? Because there are a lot of different variables in the room that affect the ability to see an image, and also, it’s subjective. If you have great eyes and can see the image just fine but someone who struggles a little more can’t make out the details, then that projector probably isn’t bright enough for the space or is even too bright (see Washout from edition 3), even if you think it is fine. There are general standards out there that can be adhered to, though, so we will go over those here briefly and you can build on that knowledge later with more research, if you want. If you read editions 2 and 3, then you have heard us say that projector brightness is measured in Lumens. You may see ANSI Lumens or Center Lumens, and these can be different numbers. Why is this? ANSI Lumens are defined by the American National Standards Institute, and “measures the overall amount of light the projector delivers.” Center Lumens just measures the “center spot,” which is likely the brightest spot on the screen, since no projector can deliver uniform brightness across the entire screen, so “center lumens” is likely a higher number than ANSI lumens. I wouldn’t say that one is better than the other, and neither can the industry at large, because you will see different people duke it out over why they prefer one to the other, but just note that they are different.

Ok, so, where am I going with this? You just want to know how bright the projector needs to be, and I’m giving you a vocab test. Well, bear with me, because here is one more term that I need you to know, and that is Foot lamberts. 👣 Yes, this is a real term. Once you’re finished chuckling, here is why you need to know what they are: these help you determine if the placement of your projector creates a viewable image in your room. By following these guidelines, you can determine if you are going with the 5,000 lumen projector or the 7,000 lumen projector. To do so, the formula is (Projector Lumens ÷ Screen Area) x Screen Gain = ftL

FOOT LAMBERTS AMBIENT LIGHT EXAMPLES
16 – 29 Dark Room Home theaters
30 – 39 Low Ambient Light Darkened rooms, no windows, etc.
40 – 59 Medium Ambient Light Classrooms, well-lit conference rooms
60+ High Ambient Light Auditoriums, lecture halls, etc.

The previous chart will help you determine if you are in the right ball park for brightness. Let’s pretend you have a 220” screen with 1.0 gain (see edition 2 where John talks about screen gain) in a lecture hall, and you got a great deal on a 7,000 lumen projector. Will it work? (7,000 lumens / 150sq.ft ) x 1.0= 47 ftL. Assuming the auditorium is well lit and has a lot of ambient light, this is probably NOT a good fit for the space. Something in the 9,000 lumens or more range would be better suited because it is 60ftL or more.

There are handy calculators out there on the web to assist you in this math so you don’t have to keep doing it yourself, but the next time someone comes to you asking for a suggestion, if you have bits of this info, you can help narrow down their search, and more importantly, be the hero!

Vocab Test Time!

Are these the most detailed definitions? No – we are not a dictionary, nor the AVIXA CTS Prep book. Will someone message us after still telling us how much we missed? Possibly. Will these get you a basic working knowledge of these terms and why they matter? We hope so. Plus, we are 99% sure they will help you shave a few strokes off your golf game. ⛳

  1. Aspect Ratio – the relationship of the height and width of your image (i.e. 4:3, 16:9, 16:10). Essentially, describes the shape of the screen.
  2. Throw Ratio – the relationship of the distance from a projection screen and the width of the screen. If you have these two pieces of information, you can easily calculate your throw ratio to determine which projector lens you need if a manufacturer doesn’t have a lens calculator on their website.
  3. Foot lamberts – Yes, this is a real measurement. Essentially, it is a unit of measurement used to determine how bright you need your projector to be. If you want to get more technical, it is equal to one circular candela per square foot (if this seems like a silly term, take it up with the Society of Motion Picture and Television Engineers who use it).
  4. Frank Lambert – Patriarchal figure in the Emmy Winning show ‘Step by Step.’
