For the past several years, projectors have been an essential part of our daily life. Needless to say, it’s quite annoying and exhausting to a crowd over one monitor or tries to see it from the back of the room. That’s where projectors swoop in to save the day and allow maximum gain from the prepared material.
Now, say you’re presenting in an amphitheater, your material is composed of several presentations; each one complementing the other. They’ll all have to be shown at the same time. Your only solution here is to hook several projectors to your device in order to allow your audience the complete experience.
This procedure may sound complicated, or you may imagine that you’ll need a lot of extra hardware/software to get it done, but that can’t be further from the truth.
USB to HDMI/VGA:
One of the most prominent features that can account for the progress of the technology involved with desktops and laptops is the variety of ports that they now entertain. VGA, USB2, USB3, and HDMI. Each one of them is designed to carry specific sort of data, even the inner structure of the cables that support them is quite different.
Nevertheless, tech guys have not allowed this difference to hinder them. They slapped one port on one end of a box, say that was a USB port, then they put another one on the other side of that very same box, an HDMI for instance. And with the correct cabling and minding what was outgoing and ingoing, they created the perfect customizable link between any device and any projector.
In our specific case, one end will go into the USB port on your computer while the other will receive the HDMI/VGA cables coming from the projectors.
The USB to VGA retail for anything from 9$ to 100$, while the USB to HDMI can cost you 6$ or 140$ or anything in-between.
Here you’re to purchase a small adaptor that will allow you to have three VGA ports rather than the one, or in some computers two, that you already have. This little device can cost you anything from 6$ to 200$ depending on the number of slots offered and the type of desktop that you have.
Connect the splitter to your device through the VGA port, then connect the VGA cables to your monitors. Check your users’ manual for the name assigned to the splitter it could be VGA or Computer or whatever the factory chose to call it. Power up your device, projectors, and monitors; open the menu on your projector, select the VGA, and that’s it.
This is one of the solutions that give the illusion of complexity, yet, in reality, it saves the user a lot of hassle. Though we’re going to focus on one specific model in this category; as it serves our exact needs, there’re plenty of models in the market now.
Our chosen one is the Matrox TripleHead2Go Digital. All you have to do is connect one cable to your computer and one cable to each of your three monitors, and that’s pretty much it. The TripleHead2Go enjoys plenty of advantages over its competitors in the market today.
Primarily simple usage but also, it’s small and compact, works with PC or Mac all the same and works with your existing GPU card as to not cost you any extra bucks. It also doesn’t come in touch with your device in any way other than a cable, so it maintains your warranty in place.
Technology evolves literally by the minute. One day you think something is utterly impossible, and the next day, it becomes the new trend. Now there are USB-HDMI dongles that connect your computer and monitor wirelessly.
This dongle is inserted into your monitor, connected to your network and voila! You can mirror anything from any device connected to that network onto your monitor. An excellent example of these devices is the Airtame which is in the size of a large USB stick.
It’s customized towards the educational process as it supports an extremely user-friendly interface and procedure. Wireless is now the way to go about things, so small dongles may very well be the future of bulky projectors.
