In today’s classrooms, many teachers and students start to use tablets during the class. However, if we need to present slides, many teachers still use HDMI cables to connect computers to projectors for presentations. While this technology has its advantages, there are also drawbacks that should be considered before using HDMI cables in the classroom. HDMI cables take up space and can be difficult to manage when you need to move around your classroom. But there are other reasons why you should consider removing HDMI cables from your classroom.
4 Reasons to Remove HDMI Cables from The Classroom
HDMI Cables Can Be Dangerous
It’s true that HDMI cables can be dangerous. Under certain circumstances, HDMI cables can cause large sparks. The sparks can cause the cable and the surroundings to catch fire. And they can also pose a safety hazard to children. So, if you’re not sure whether or not you need HDMI cables in your classroom, consider removing them.
HDMI Cables Are Prone to Damage
If you’re using HDMI cables to connect devices to TVs, you need to make sure that you’ve got them properly secured. A loose cable can easily become damaged, causing an electrical short circuit. Even small gaps in the wires of the cable can cause dangerous sparks. Then they can cause a fire hazard as well as damage to other equipment.
HDMI Cables Take Up Space
One of the biggest disadvantages of having HDMI cables in the classroom is that they take up space. If you have a large room with limited space, then you might need to think twice before purchasing more cables. Cables also limit teachers and students’ mobility which makes it hard for people to walk around while doing the presentation.
HDMI Cables Cannot Fully Support All Devices to Share The Screen
If you want to share your tablet or smartphone’s screen, it’s impossible to use an HDMI cable to connect your device to the display or the projector. However, you can still share your device’s screen without HDMI cables. If you are using a smart TV as part of your classroom technology setup, you can usually share the screen of your device wirelessly. Sometimes it may not work according to your device’s operating system. To ensure all your devices can wireless share the content, you can install a professional wireless presentation system. ASTROS wireless presentation solutions support Windows PC, MacBook, iPhone or Android smartphone to share the screen wirelessly. For teachers, you don’t need to worry if students share inappropriate content, because you can easily control the sharing content through the moderation mode.

The Benefits to Get Rid of HDMI Cables
As we said, even without HDMI cables, you can still enjoy screen sharing. A smart TV or a wireless presentation system can help you do so. Once you remove HDMI cables from the classroom, you will definitely find the following benefits.
Students Can Learn Better
If you want to make sure your students are getting the most out of their classroom experiences, consider removing HDMI cables from your classroom. These cables limit the amount of space available to students to move around and engage with one another. Removing these cables allows students to move around more easily and interact with one another.
Teachers and Students Can Save Time
If you choose a wireless screen sharing solution, students can sit on their seats and share the screen at the same time. Teachers can also walk around and share the screen anywhere in the classroom. They don’t need to walk to the laptop which is connected to a TV with a HDMI cable to share slides. Besides, it’s quicker to share the screen wirelessly than using HDMI cables.
Create More Student-Centered Classroom
Students can easily share their ideas on the screen from anywhere in the classroom. Teachers are no longer a transmitter of knowledge. Students can contribute what they know and interact with teachers too. A wireless screen sharing solution can make the classroom a more dynamic place.
Unleash Creativity in The Classroom
Using a wireless screen sharing solution means teachers can come up with more creative classes. They don’t need to limit themselves to what a laptop can do. They can ask students to use tablets or smartphones to do projects. It’s also an opportunity for students to do their homework without restriction.
Conclusion
With the rise of digital devices like tablets and smartphones, teachers can think about giving up using traditional cables in their classrooms.
