LCD Projector For Classroom Use
LCD projectors allow images to be projected in a crystal-clear format, so all students can easily see the lesson content. This is a big advantage over the previous generation of projection technology, where images were often blurry and small.
Look for a classroom projector with a high brightness level to ensure your images are clear in varying lighting conditions. Many models offer connectivity options for a wide range of devices.
1. Easy to Set Up
With the right classroom projector, teachers can easily connect wifi projektor to their computer, AV equipment and other devices for presentations, videos and other visuals. They can also use the projector for class notes and other materials in a crystal clear format so that all students can see.
Most education projectors come with at least a VGA and composite video connector for connecting to your computer or video equipment. You can even find some that have HDMI and MHL (Mobile High-Definition Link) connections for displaying mobile content from Android devices. These types of projectors can also be monitored remotely using an RJ45 network port, making them easier to manage and maintain in a large school setting.
Some education projectors can be set to display 3D images – an excellent feature for specialized lesson content. However, it’s important to choose a projector with a lower input lag and 240Hz refresh rate so that you can enjoy the best quality image. It is recommended that you test your projectors before installing them in your classrooms so that you can be sure they are working properly.
2. Easy to Maintain
A projector allows for screen size flexibility, while TVs are limited to a predetermined set of sizes. Whether you want a 75″ screen or a wall of images, classroom projectors can handle it. Moreover, they offer better clarity, reducing visible pixelation and higher compatibility with high-definition source content.
Lamp-based education projectors tend to be less expensive, but constant need for bulb replacement and cleaning adds to their total cost of ownership. Additionally, traditional bulbs fade in color and brightness over time, interfering with image quality.
Smart projectors, on the other hand, are more cost-effective and easier to maintain. LED-based projectors use a long-lasting, maintenance-free light source that eliminates the need for frequent bulb changes. They also have quick startup and lower running temperatures, making them more energy efficient and quieter than lamp-based models. They are also eco-friendly, using a mercury-free, environmentally safe light source. This minimizes environmental impacts and provides a safer workspace for teachers. Adding network capabilities to these displays empowers IT managers for powerful centralized monitoring, control and power scheduling. They can also be easily integrated with Creston, AMX or PJ Link control systems.
3. Engages Students
The ability to engage students is a critical factor in student retention. Projectors allow instructors to make their lessons more interesting by displaying images, videos and text in crystal-clear format. This helps to keep all students engaged and makes it easier for them to follow the lesson.
This technology is particularly useful for students with different learning styles. Auditory learners learn by listening to teachers and may find it challenging to remember key points without visual aids. With projectors, auditory learners can return to slides in presentations or replay segments of videos to review important information, allowing them to catch up.
Teachers can also use interactive systems developed for schools that combine an LCD projector, a computer and handheld “clicker” devices that function like multi-button remote controls. The instructor creates software templates that display a quiz on the screen; when the students press buttons on their clickers, the results appear on the projected image and are displayed for all to see. This allows the teacher to take attendance and assess student comprehension of the lesson.
4. Versatile
With a variety of teaching materials available online, teachers can easily show videos to their students through an LCD projector. These could be a documentary on YouTube, a movie from DVD or a self-produced video taken on a field projector for daylight trip. This helps engage the students to pay attention to their lessons.
Higher resolution education projectors like the Dell 1409X offer more pixels to eliminate visible pixelation, which is ideal for classrooms that utilize high-definition source content. They also have the ability to operate in more ambient light, without sacrificing picture clarity. However, higher resolution projectors are usually more expensive than lower-resolution models.
Some schools have limited budgets, but the cost of a new projector has come down considerably in recent years. There are now many affordable models in the 4 to 5 pound range that provide a wide range of features and are easy to transport. Some even have a built-in speaker for sound. They can be used to display web pages, spreadsheet data and presentation software. These projectors also have a SuperEco Mode to help lower power consumption and extend lamp life.
5. Affordable
When compared to traditional whiteboards and overhead projectors, LCD video projectors are a classroom must-have. The technology is affordable and easy to set up and maintain. Combined with a digital media player, students are given the opportunity to experience new learning experiences that would not be possible otherwise.
The ViewSonic PA700W is a great example of an affordable yet versatile school projector. The contrast ratio is a very respectable 15,000:1 and the WXGA resolution provides plenty of screen size options. There’s even a dedicated Infographics Mode that offers extra clarity for text and graphics. This model also has two HDMI ports and two VGA ports, a monitor out port and a USB display port to allow teachers to connect and present from multiple devices simultaneously.
Another cost-effective option is the NEC MC423W which features an impressive lamp life of up to 20,000 hours. It’s also environmentally friendly with ECO Mode, a carbon savings meter and energy-saving features like quick startup and auto power off. The ultra-lightweight design is ideal for portable use in a variety of settings and features a built-in speaker that delivers room-filling sound.
