Just like modern televisions, projectors today have certain ports that allow them to receive as well as display images that are produced by a laptop or computer. As long as you have the required cables, you can connect your laptop to a projector as effectively as you would a desktop computer. For years, connecting a laptop to a projector hasn’t been challenging, all you needed to do was plug in the VGA cable, then push F5 and start your presentation or watching. However, with the technological advancements today, new laptops are being made without VGA ports, which requires users to carry around different adapters to make everything work. Regardless of whether you need to project from your laptop for home or office use, it is important to determine whether you need a wired or a wireless connection, depending on your needs and preferences.
Wired connections for laptops on the projector
When it comes to securing a laptop connected to a projector, wired connections are the most advisable. The older laptop models have VGA ports, while the newer models have digital ports which are responsible for sharing the HDCP information with the display to facilitate running and display of the content. If the room you are using for connection has VGA cables, you will require an HDMI to VGA adapter for connection, and there are a variety of those available. The VGA to HDMI adapters is different in function, as there are some which carry video signals exclusively, while others can alienate the audio signals from video signals so that they are sent over legacy analog systems.
Wired connections however have a limitation in that, lost laptop models have different video outputs which all require different types of adapters. There are some laptop manufacturers like Lenovo, Dell, and HP who produce laptops with all four wired interfaces, while some have just one. The new MacBook for instance has a USB-C Thunderbolt video output, or a mini display, while the older MacBook model might have a full-size HDMI or VGA port instead. These adapters need to be bought and managed, and as they often get lost, it becomes challenging to configure the right adapter for a presentation on time.
Wireless alternative to connect your laptop to a projector
Depending on whether you want a projection for your home or the office, there is an option of wireless connections if you don’t want a wired connection for your laptop. Laptops are a great way to share short videos and photos on your home projector especially on intimate and social functions. If you want to share some video clips of an overseas trip or images of the couple on the wedding day, a laptop can be connected wirelessly to the laptop and serve a wider audience. This is however possible if you have an Apple TV for Mac users or Google Chromecast which both can allow connection of the laptop to the projector wirelessly, without the need for a cable.
The case is slightly different if you have wanted a projection for the office and not for your home. The first step is choosing the right system, after identifying the office space you are working with. Office spaces have meeting rooms and collaboration spaces where meetings are held. These corporate meetings are essential, and also very expensive; hence it is very critical to start a meeting at the scheduled time to meet low costs.
If you have a large audience, Google Chromecast might not be the most reliable option, as it wasn’t meant for many users. This application doesn’t guarantee the security of your content from the wireless snoopers, hence the need for different commercial wireless solutions for classroom and business collaboration.
It is imperative to choose the right solution for your meeting space or collaboration space, and it is a challenging task as well. For any wireless connection, you want to have for a projector, some things should be considered, such as a solution that doesn’t require a network connection to function. This is essential if you want to get rid of presentation traffic which otherwise bogs down your network.
You should go for a solution that uses a device easy to use so that anyone can operate it in seconds without necessarily needing an app. The more affordable solutions need a company-wide deployment of additional software, which isn’t effective because most visitors are hesitant to install third-party apps on their laptops just for presentations.
The right wireless solution for connecting laptops to a projector should use corporate-grade encryption security to ensure that hackers and cybercriminals don’t listen in or record confidential information from presentations.
The BenQ InstaShow
This is a new wireless alternative to connect your laptop to a projector. The BenQ InstaShow is a screen mirroring system that is very simple to use, and it allows many presenters to connect to a projector wirelessly by just tapping a button. All they need to do for this to work is to plug in a transmitter to the USB-C Thunderbolt port or the HDMI port on the laptop, then push the button for a connection to be established. This alternative does not require any networking equipment or requirements, and no software is required to run.
This alternative allows you to connect the USB-C transmitters to phones and devices such as Samsung Galaxy and iPad Pro for sharing of content from other devices. The BenQ Instashow unit is one of the safest wireless systems on the market today, as it uses very advanced and progressive encryption for each presentation. This unit has also been certified and verified against the known shortcomings of connection systems and has been among the fastest-growing wireless screen mirroring solutions for corporate settings and classrooms.
There isn’t a very complicated way to connect your laptop to a projector, just remember to turn off the computer and the laptop first. The video cable should be connected to the projector from the external video port of the laptop, and then plug the projector into an electrical outlet. Power the projector on, and turn the laptop on as well. Should you require audio for your presentation, connect the audio out port of the laptop to the projector or another audio system. You can hold down the Function key to sync the projector and the laptop, and use either F4, F5, F7, or F8 keys for toggling depending on the type of laptop you’re using.
