Buyer’s Guide: Projectors for Classrooms
If you need to buy a projector for an educational institution, you should pay attention to certain characteristics.
Determine the required screen height
The fundamental value for selecting a screen is the viewing distance. Experience with projectors has shown that in educational institutions, the optimal viewing distance is 6 screen heights. So for a 128cm high screen, the optimal viewing distance is 7.68 meters (1.28×6).
Thus, a screen with a diagonal of 80″ is the minimum possible for the normal class. However, it is necessary to consider that, according to the requirements, the distance from the floor to the bottom edge of the screen should not be less than 80 cm. Therefore, it is also important to consider the height of your room.
Determine the format of the screen
We saw that the height of the screen is critical. Another important parameter, is the format of the screen, ie, the ratio of the screen width to its height. The 4:3 format, which is slowly becoming a thing of the past, has been replaced by the 16:10 format, which is a logical development of the popular 16:9 format, but at the same time, it is 11% bigger.
Many models of modern notebooks feature this aspect ratio. Most Word® documents, PDF files, and websites are designed in portrait format, with the long side vertical. Since 16:10 is higher than 16:9, it fits better. Again, you will see 11% more information than 16:9.
Pay attention to the brightness of the projector
The brightness of a projector is stated in lumens (Lm), which refers to the illuminance per square meter of surface. The brighter the projector, the higher the value. As a rule, the higher the brightness, the more expensive the projector.
The required brightness level of the projector for your classroom is determined by the lighting conditions in the room. To find out the sufficient brightness of the projector for your room, you need to multiply the illumination in the room, in which you plan to view, by the screen area. It is generally accepted that the optimal brightness of the projector should be 10 times this calculated value. For classrooms, the minimum level of illumination in the SNIP is set at 500 lux.
That is, if you do not reduce illumination in the classroom, for example, by turning off lights or curtains, for a screen size of 80″ 168 x 128 cm (2,15 sq.m.) the optimal projector would be a brightness of at least 10 000 Lm (500 lux x 2,15 sq.m. x 10 = 10 750 Lm).
However, the experience of projectors’ operation in the majority of classrooms in Russian schools shows that brightness of 3,300-3,800 Lm is considered acceptable with some limitations.
A thoughtful and prudent decision before choosing a projector brightness is to measure the light level in your classroom where you are going to use the equipment. This can be done with a simple and inexpensive device called a lux meter.
Choose the type of projector
Besides the common projectors which are usually located far enough away from the screen (often not closer than 2 meters), short-throw and ultra-short-throw projectors are widely used in the education sector.
Short-focus projectors can be placed at a distance of 75-100 cm from the screen and carried from classroom to classroom. Ultra-short-focus projectors are equipped with a special wide angle lens which allows projecting a 100″ diagonal image from a distance of about 25-50 cm from the screen, they are usually placed above the screen on a permanent basis by fixing it on the wall or the ceiling, i.e. almost above the screen.
With this projection distance, the shadow of the speaker is virtually invisible on the screen, and the bright light from the projector does not dazzle him when he looks at the audience.
Choose the resolution
Currently, the most affordable and therefore most in demand are projectors with a resolution of 1280×800 pixels (WXGA) and a 16:10 aspect ratio. More expensive projectors have a resolution of 1920×1200 pixels (WUXGA), where the image, text, and fine details look much better and clearer.
The high resolution could be crucial for quality learning processes, effective design developments, and medical research in order not to miss any detail of the image. Of course, you need to consider the resolution of your device from which you feed the signal to the video projector.
Check the interactive features
Projectors these days are more than just devices that project images onto a screen. The leading projectors on the market have smart, interactive features that allow you to write text, make graphs and draw on the projected image.
The mouse function also allows you to control your computer directly from the screen. This means that you can work with teaching materials and software that are on the computer, as well as use various tools. This opens up exciting possibilities for teaching and learning.
Check the ease of use and connectivity
Numerous projectors support multiple signal sources. However, you should buy a projector that has input jacks that are available on all of your intended signal sources (computers, camcorders, players, etc.). If you have multiple signal sources, to avoid buying additional splitters and manually switching cables, make sure the number and types of connectors on the projector match the number of sources and the types of their connectors.
For example, if you have a computer and a media player and each has an HDMI connector, it makes sense to purchase a projector with two HDMI connectors or to use an HDMI 2×1 signal splitter to avoid running two HDMI cables to the projector.
The concept of “bring your own device and show it” is becoming more and more common. Some projectors have the ability to wirelessly play video signals from computers, tablets, phones, and other mobile devices, and this additional projector feature help to realize this concept. This feature can often be activated by plugging a special wireless module into the projector’s USB port.
Certain models of projectors allow you to play content from a USB flash drive. By inserting a USB flash drive or plugging a hard disc directly into the projector you can start projecting its graphic or video files without using a computer.
Both teachers and students need to be able to start the projection easily, so choose a projector that you can simply plug into and quickly start projecting.
Can the projector play sound?
An important addition to the projector can be built-in speakers, which in some cases will do without the need to connect additional speakers. Such built-in speakers usually have a maximum power of 10 W, which is comparable in volume and sound quality to a home TV.
Nevertheless, the presence of pass-through outputs (Mini-jack 3,5 mm, 2xRCA) to connect the projector to the existing speaker systems will be important to simplify the connection of devices and reduce the number of cables that will be needed to organize image playback with sound.
How noisy is the projector?
In order not to disturb the speaker, distract the audience, or force them to listen to the speaker’s speech, it is important to how quiet the projector is. At 30dB, a projector is considered virtually silent.
FAQ on Projectors for Classrooms
Are classroom projectors easy to operate?
This is a difficult question to answer as it depends on the projector and the person operating it. Some projectors are very user-friendly while others require a bit more knowledge to operate.
How many lumens should a classroom projector have?
There is no definitive answer to this question as the number of lumens required for a classroom projector will depend on a number of factors, such as the size of the room, the ambient light conditions, and the screen size. However, as a general guide, most classroom projectors will require between 2,000 and 4,000 lumens to provide a good quality image.
How do projectors in schools help in teaching?
Projectors help in teaching by giving instructors the ability to display multimedia content on a large screen. This allows for a more engaging and interactive learning experience for students.
How many lumens do I need for a classroom projector?
Classroom projectors typically need around 2,000 lumens to provide a clear image.
Is a Projector for the Classroom Worth Buying?
A projector for the classroom can be worth buying if it is used correctly and fits the needs of the students and the curriculum.
Gone is the era when learning was limited to notebooks, textbooks, and posters. Technology has permeated every aspect of our lives, including learning. Multimedia technology in the classroom is no longer a marvel of technology. Schools today are choosing digital solutions in the classroom for effective, convenient, useful, and interactive learning.
An important component of today’s multimedia solutions in the classroom is the projector. A video projector ensures that every student gets an understanding of the topics covered in class. In addition, modern interactive projectors are a great tool for keeping students’ attention.
Buying a new projector for an educational institution can seem like a daunting task, especially for teachers who are not well versed in the abundance of acronyms and technical terms.
No matter how diverse your multimedia content or interactive crocs are, a teacher using a dim projector with poor image quality is not going to ignite the minds of students in the classroom.
Students and learners need to be able to see the projected image clearly from anywhere in the classroom. The clarity and brightness of the image really make a big difference in how attentive students are and how well they remember what they learn in class.
