5 Reasons to Invest in Training

by | Feb 27, 2024 | Projectors, Uncategorized

Whether you are the owner of a small AV integration firm or a manager at a large national integrator, chances are, you are faced with the same struggle of finding the time to attend training for yourself or send your employees for training. Oftentimes, this can be costly and time consuming. However, the benefits of a highly trained workforce will almost always outweigh the short term costs.

Here are 5 reasons you should consider training for yourself or for your staff:

1. Staying on Top of the Latest Technology Trends

I think we can all agree that, like many industries, the world of commercial AV technology is constantly changing and evolving, not only with the technology itself, but with the needs of our customers. A few examples include the major advancements in Direct View LED (DVLED) for large video-wall displays, and the skills required for successful installations. If you are not aware of the latest trends or not equipped to handle them, you may find yourself losing business to competitors.

2. Enhance Customer Service

Think about a time when you were interested in making a purchase (any type of purchase — it doesn’t have to be technology), and you felt your salesperson was not educated about the product. How did that make you feel about that company? Your customers will always get better service from a well-trained employee, whether it is your salesperson, project manager, or installation technician.

3. Keep Your Certifications Current

While there are many certifications in our industry, the most common and well recognized is AVIXA’s CTS. The CTS, CTS-I, and CTS-D are important designations and require a significant amount of time and effort to achieve. Any CTS holder understands the importance of continuing education and obtaining CTS RUs in order to maintain their certification. RUs can be obtained in a variety of different methods, including live classroom training and various trade events, like the Exertis Almo E4, and webinars.

Customer Service

4. Less Supervision

As an owner or manager, you are faced with the difficult challenge of running your business and managing employees, often while being involved in work that could be handled by properly trained employees, freeing you up for other tasks. Well-trained employees will be able to work more independently without the need for constant guidance and will help your staff be more confident and satisfied in their job.

5. Reduce Employee Turnover

Hiring new employees can be time consuming, expensive, and involve risk if the right hire is not made. Providing training opportunities for your employees shows them your interest in advancing their professional skills and will enhance company loyalty and increase employee contributions to your business. Often, employees thrive on knowing they are a key contributor to their company as much as they enjoy monetary compensation.

Exertis Almo’s E4 Experience has stops in DC Metro on March 5th, and in Chicago on April 16th. In addition to an exhibit hall with the newest technology from over 40 top manufacturers, attendees will have the ability to earn AVIXA CTS RUs throughout the day via classroom training. If you are in one of these regions, I encourage you to invest your time with us for this free one-day event.

Projectors vs. Displays: Audio-Visual Solutions for Equitable Hybrid Learning Environments

by | Jul 13, 2023 | Collaboration, Education, Projectors, Uncategorized

Over the past few years, hybrid learning has quickly become the new normal in a variety of educational spaces. In order to accommodate the needs of in-person and distance learners alike, modern educational environments require innovative audio-visual solutions to ensure that classrooms provide a productive and equitable experience for everyone involved.

This poses an important question. Display or projector?

hybrid-lecture-projectorWhen designing or renovating a classroom, there are several key factors that affect an integrator’s decision in choosing to install a display or a projector. Generally speaking, the decision is based on the room size, seating layout, and light levels of the overall environment – both natural and overhead lighting included.

Displays are more commonly utilized in smaller meeting rooms, as they provide clear, crisp images for students viewing at a short distance. In larger classrooms of more than 20-25 participants, integrators usually prefer to install projectors, as they better accommodate the students seated in the back of the classroom and serve as a more cost-effective option for lecture halls and higher education spaces.

The CMZ50 from Panasonic is an excellent addition to any mid-size to large learning environment, as the projector features high visibility and dynamic visuals in bright rooms and flexible installation for a variety of room layouts, including a 21:9 aspect ratio for hybrid learning and remote collaboration. Perfect for the education space, the projector features a compact design and long-lasting power. Plus, the simple set-up and wall-mounted installation provides crystal-clear images up to 120” with little to no chances of projector shadows from the presenter.

Although projectors are a cost-conscious choice for larger rooms, some recently designed classrooms are including both projectors and displays in order to create an equitable experience for students, no matter where they’re seated. By placing displays midway through a lecture hall, these additional screens tend to mirror the content displayed on the main projectors for students seated in the back of the room.

Panasonic’s variety of professional displays for educational spaces create fascinating learning environments that enhance classroom collaboration. With hybrid learning in mind, Panasonic’s education-focused displays are designed for simple use, 24/7 operation, and advanced adaptability to keep up with the evolving education market.

hybrid-lecture-displayAdditionally, we’ve seen an increased demand for both displays and projectors in hy-flex classrooms, which follow a small group-based layout. These learning spaces feature a main projector, or several, at the front of the classroom, but separate students into small groups, each with their own individual display at their meeting table. The professor can walk around the room and supervise the individual groups, with the capability to transmit a video feed from the small group displays to the main projector to share content with the whole class.

In fact, integrating both products into a learning space can be beneficial when there are obstacles in the way, like low ceilings or an obstructed view from a certain seat. Whether these secondary displays are presenting supplemental material or reinforcing the content on the primary projector(s), this combination of technologies is a versatile way to accommodate the needs of every student and prioritize classroom equity.

However, there are some challenges and additional elements to consider when choosing a classroom layout, including fire code compliance, natural light levels throughout the day, and the existing layout of the room. For example, ceiling technologies, like projectors and microphones, have to be adjusted to prevent interaction with fans, HVAC systems, and more.

5 Keys to Selecting a New Projector

by | Apr 18, 2023 | Professional Development, Projectors, Uncategorized

Five Things to Consider When Selecting a New Projector

When it comes to producing large displayed images of 100” or more, projection technology is the front runner when it comes to cost, ease of installation, and system maintenance over time. While projector brightness is a key consideration, it is not the only factor you should be looking at when selecting a new projector. Here are some others that I recommend you should be looking at:

1. Projection Technology

If you have been in the industry for over a decade, you likely remember regularly being asked the question, “What’s better, plasma or LCD?” We no longer have that choice since the extinction of plasma displays, however, with projectors, we do have choices in the type of technology. The most common types of projection technology are 3 LCD, 1-Chip DLP, and 3-Chip DLP, with LCoS as a less common option for commercial projectors. While both are perfectly acceptable, 3 LCD typically will produce more vivid saturated colors and DLP may produce “blacker” blacks. Most noticeably with 1-Chip DLP, because of the color wheel, the brightness or lumen output when producing color images will often be significantly lower than the specified lumen rating. 3 LCD projectors will output the full specified brightness whether projecting full white or full color images. For more detailed information regarding color brightness, check out this article.

2. Resolution & Aspect Ratio

With projection, you have three common native aspect ratios to choose from (4:3, 16:9, and 16:10). According to PMA Research, over 75% of projectors sold have a native aspect ratio of 16:10, the majority of which are WUXGA with the remaining at WXGA. Additionally, they report that roughly 20% are native 16:9, with the majority being 1080p and a relatively small segment that are native 4K. This means there is still, albeit small, a percentage of native 4:3 projectors being sold. The important thing to remember here is that you want to match the aspect ratio of your screen to the native aspect ratio of your projector. Whether you are retrofitting a new projector to an existing screen, or installing an entirely new system, you need to be mindful of this. Also, be aware of the source signal you will be sending to the projector, especially if you need to display a 4K signal. While native 4K commercial projectors are expensive and choices are limited, there are many options that are native WUXGA (1920×1200) that support a 4K signal with pixel shifting technologies, like 4K enhancement.

3. Image Position & Adjustment

in a perfect world, you would not have to worry about projector placement relative to the projection screen, however, things like light fixtures and HVAC systems can prevent you from installing the projector dead center of screen. While most projectors offer horizontal and vertical keystone correction, you sacrifice some image quality when using this. A better option is to use a projector that features lens shift, so that the image can be repositioned horizontally and vertically without any digital manipulation of the image.

4. Throw Distance/Projector Placement

the projected image size will be determined by the available distance or “throw” you have in a particular space between the front of the projector lens and the projection screen surface. Unless the projector you are considering offers interchangeable lenses, as your desired image size increases, so does the required throw distance. A key specification of any projector or projection lens is the throw ratio. For a zoom lens, this is expressed as a range of two numbers representing distance compared to the number one, which represents your image width, for example (1.35-2.20:1). In this case, this specification states that the throw distance can range between 1.35 x the image width up to 2.20 x the image width. For a 10ft wide image, the throw distance then can be anywhere between 13.5ft – 22ft. It will be important to understand any limitations regarding projector placement relative to the screen and to choose a projector that will meet those requirements.

5. Connectivity

This may seem like a no-brainer since the majority of sources are now HDMI and pretty much every projector will include at least one HDMI input, however, in many cases the projector will be mounted just below the ceiling in the middle of a room. This could be a considerable distance away from the video source. Often, for cable lengths beyond 50ft HDBaseT HDMI extenders are used to send the audio, video, and control signals a long distance over a single Cat6 cable. Selecting a projector that includes an HDBaseT input can save you money on the extension hardware, simplify the installation, and reduce points of failure.

Whether you are looking to provide large images for a house of worship, create interactive experiences in classrooms, incorporate projected images into a presentation stage, integrate a command and control center, or deliver just about any type of large displayed visual image, a projector exists to get the job done.

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).

Edition 3 of “This May Be a Dumb Question, but…”

by | Feb 21, 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 back to the 3rd installment of “This may be a dumb question, but…” In Edition 2, we began exploring the vast world of projection and it’s many facets, but specifically, we went over the differences in Laser vs. Lamp projection, as well as the foundation for choosing the best projection screen, so if you want to start there, here is a link to Edition 2.

Since projection has so many layers to picking the right solution, we are going to continue drilling down. On to the questions!

QUESTION
What is the difference between all the different projector technologies? I see 3LCD, DLP, LCOS, Laser, Lamp, etc., and I don’t understand what the difference is and when to use them.

ANSWER

In every technology installation, it is important to know the full scope of what your client is trying to accomplish. Seems simple, but you would be surprised how often the details do not come with the request. It’s not just about if you can rattle off all the projector specs. What sort of experience do they want? Do they need color accuracy because they need the best possible picture? Are they just looking at random power points and are looking for a budget option? Is it in a setting where they need a very quiet projector? There are MANY more questions involved in this decision, which we will look into more in the next few editions, but the answers to some of these questions could narrow down or determine which ‘color source’ or ‘chipset technology’ you will go with once you have decided on the laser or lamp dilemma. Before we move on, I’d scoot down to the ‘Vocab Test’ and refresh your memory on the 3 main projector technologies we see today in the Pro AV space.

Alright, on to the cheat sheet. To break it down as simply as possible, we’ve created a brief guide below.

Note: this is not the most comprehensive list of Pros and Cons, and like everything else in AV, it is subject to interpretation and experiences, but this can help those little light bulbs go off in your head when your customer starts describing their upcoming projects:

TECHNOLOGY VERTICALS BEST SERVED PROS CONS LASER OR LAMP?
1 or 3 chip DLP1 -Education
-Corporate
-House of Worship
-Bars/Restaurants
-Museums
-Large Venues
-Cinema
-Simulators		 -Deep Blacks
-DLP uses mirrors to reflect light, so there is no degradation over time (aka longer lifespan)
-Minimal motion blur		 -Doesn’t appear as bright as LCD
-‘Rainbow effect’ due to the spinning wheel in 1-chip models		 Can be both
3LCD2 -Education
-Corporate
-House of Worship
-Bars/Restaurants
-Museums
-Large Venues		 -Most cost-effective up front
-Higher brightness for comparably priced models
-Most portable		 -LCD degrades overtime, causing brightness and picture degradation
-Motion blur can be an issue		 Can be both
LCoS3 -Corporate
-Cinema
-Simulators
-Museums		 -One of the best native contrast options
-Deep blacks
-Native 4k in most cases		 -Heavier and not as portable
-Like LCD, LCoS can have an issue with motion blur in fast scenes
-Expensive		 Can be both

In Edition 4, we will discuss the next step in our process once we determine lamp or laser, and which projector type (DLP, LCD, or LCoS) – which is determining placement of the projector, how bright we need it based on our room, and screen size. It will require some math, so bring your scratch paper. ✍️

QUESTION
I’ve noticed that sometimes projection screens aren’t always white. Sometimes they’re off-white, or gray. Why would that be?

ANSWER

I’ll answer your question by starting with a fun fact!The term “silver screen” was coined in 1920s when projection screen manufacturers and theater houses started using silver paint on screen surfaces. At the time they found that a silver screen made the images “pop” more, provided better contrast4 (very important in black and white films), and reduced blurriness and washing out of the images. This makes sense if you really think about how reflective the color white can be. If you’ve ever walked outside on a sunny day when the ground is covered in snow, you know how incredibly reflective and blinding pure white snow can be. Have you ever been blinded by the gray snow on the side of the road after the plows?

There’s really two advantages that come from using a screen that is gray instead of white. Firstly, by reducing the overall reflectiveness/reflectivity/reflection-factor of a screen, you can avoid the projected image from being blindingly bright (washout5). Well, in addition to combating washout, it can also help with ambient light issues. In the last issue, we covered how ambient light in the room can interfere with the projected light you actually want to see.

Another way combat that issue is by using a darker screen. The gray material will absorb the ambient light better and allow the desired light to shine (pun definitely intended) through. Additionally, just as in the 1920s, using a gray screen can help improve the quality of motion pictures. Technically speaking, projectors can’t project the color black. So, if you’re watching a dark action movie, like John Wick (which you totally should be, because it rules), then you’re going to want to be able see the action clearly and crisply. Having a darker screen will help the projector produce dark colors better, and allow for deeper contrast, which will help the action and figures stand out more clearly. Now, this isn’t to say that you should always use a gray screen, there are many situations in which a white screen will work just fine. surface-reflection-toolThe brightness of the projector, the projector technology being used (see previous question), the light in the room, the intended uses of the system, and the budget, are all key factors that you need to consider when building a projection system. The important thing is to make the right choice by evaluating all of the factors. There are many tools out there that can help you determine which screen surface is right for you. I personally like this one that our friends at Dalite have come out with 📽️ surface selection tool.   [click image to enlarge →]

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 impress your grandparents when you reset their WiFi.

  1. DLP – Stands for ‘Digital Light Processing,’ a type of chipset in display and projector technology that uses reflective surfaces/mirrors and color wheels to project light and color onto the screen.
  2. LCD or 3LCD – Stands for ‘Liquid Crystal Display,’ or ‘3 [Chipset] Liquid Crystal Display,’ which is a type of chipset that uses the white light from the source (lamp or laser) and reflects them through 3 light panels. The projector controls how much light passes through these panels to then create the image on the screen.
  3. LCoS – Stands for ‘Liquid Crystal on Silicon,’ which is a little bit of a mix between LCD and DLP technology. LCoS projectors use the mirrors of a DLP projector with the liquid crystal panels of an LCD to create bright, beautiful images, but without the ‘rainbow effect’ of DLP from the spinning color wheel.
  4. Contrast – A measurement/description of the differences between the white and black colors in a projected image.
  5. Washout – When the projected image is too bright or has too much white light is reflecting, detracting from the overall image quality.
  6. Wipeout– America’s Largest Obstacle course game show.
