In this guide, we shall be discussing the advantages of projectors. If you are considering getting a projector, after reading this review, you’ll want to acquire one for yourself.

What is a Projector?

A projector is an output device that is capable of connecting to a computer, which may be another option for a monitor or television in terms of displaying pictures to a large number of people. It takes images generated by a Blu-ray player or a computer and projects them onto a large surface like a wall or white screen. Projectors come in many shapes and sizes and are used in conditions like a classroom, home cinemas, office training or presentation sessions, etc. The projector looks like the below picture.

Commonly, projectors come a few inches tall and about a foot long and wide. They may be portable and freestanding and can be mounted on ceilings. Ceiling-mounted projectors come in a large size with a long-distance like 30 feet or more. The main applications of these kinds of projectors are places of worship, conference rooms, classrooms, and auditoriums.

On the other hand, some of the projectors have the potential to support Wi-Fi and Bluetooth connectivity, and most projectors are designed in a way that they can have different input sources, such as VGA ports for older devices and HDMI ports for newer equipment.

In the early time, there were needed much high amount thousands of dollars for high-quality projectors, and more than a hundred dollars were required for bulbs alone. In modern times, the cost of projectors has decreased, like a bright, high-quality projector has been reduced to a few hundred dollars with the help of LCD and LED light sources.

What Are the Parts of a Projector?

A typical modern projector is made up of the following parts.

  • Lens: The lens of the projector is what beams or projects the image towards a given screen. Some lenses are of the zoom or telescopic variety that enables you to do lens zoom on the image, making it as large or as small as you want without physically moving the projector.
  • Projection Lamp: A lamp that’s either of the halogen or LED (light-emitting diode) variety assists in the projection of the image. How bright the projector is, depends on how powerful or how many lumens the projector lamp has.
  • HDMI and USB Connectors: The HDMI connectors are obvious the HDMI output ports of the projector that allow you to connect source media like Blu-Ray and DVD players as well as game consoles unto it. The USB connectors are usually for flash drives or to share power with certain mobile devices. Some projectors have extra A/V ports for composite and component cables as well.
  • Power Connector: This is where you’re supposed to plug in the cable that enables your projector to plug into the power socket.
  • Speaker: Some projectors come with their own speaker that you can bypass for a Bluetooth speaker, a wired soundbar, or a home cinema sound system.
  • Control Panel: Speaking of which, aside from the remote or app you use with your phone, the projector should have a control panel that might be composed of a series of buttons you could press or an LCD touchscreen you can manipulate depending on how high-tech your projector is.
  • Remote Control: Remote controls, also known as remote receivers, enable you to control your projector from afar without having to push any buttons or touch the screen of your projector control panel.
  • LAN Connector: A separate LAN connector is available in case you want a wired Internet connection for your projector using LAN cables instead of depending on its Wi-Fi connection to your home Internet router.
  • The Fan, Intake Vents, and Exhaust Vents: Inside the projector is a fan that cools it down as you use it with the hot LED lamp. It sucks up the air around the device using the intake vents then dissipates the heat using the exhaust vents for efficient cooling action.

How a Projector Works

A projector works by shining light through a small transparent lens. There are multiple projector technologies available that enable you to project the digital image from your source media in a direct manner, such as using lasers instead of LEDs. The projector that replaced the slideshow projector in the 1990s to 2000s—the digital video projector—is a culmination of all the technologies dating back to the camera obscura and magic lanterns of yesteryear to the movie projectors and slide projectors of the early 20th Century.

The Liquid Crystal Display (LCD) projector was the projector type that dominated the video projector used mainly for business presentations and computer monitor mirroring. They were eventually also used as television alternatives as tech became more common and available. You now have the mirror-based, prism-like Digital Light Processing (DLP) projectors as well as the LCD/DLP hybrid known as Liquid Crystal on Silicon (LCoS) projectors that mix LCD tech with DLP prisms together.

Types of Projectors

I’m here to tell you about the types of projectors, so you get to know a little bit more about the projectors before getting into its advantages. So, after reading this, you will have all the answers to the questions you have or might have.

Advantages Of Projectors

  • Largest possible picture. Front projectors generate the biggest possible image size. You can use them to create the very large screen experience of a commercial movie theater in your own home. In theory, actual image size can go up to 300″ diagonal or more. But in reality the size of any given projector’s image is limited by its light output. Nevertheless, most projectors produce beautiful images at sizes of 90″ to 120″ diagonal, which is far larger than anything you can get with flatscreen TVs or rear-projection TVs.
  • Smaller images a great option also. Perhaps you don’t want a huge image, or maybe you don’t have space for one. If this is the case, a projector can be used to throw a smaller image, say about 60″ diagonal. So it can serve as an inexpensive substitute for a 60″ plasma TV. At this image size, the picture is usually very bright and can be used with some of the room lights on. Given the low cost of many entry-level projectors, this can be the least expensive way to get a 60″ picture on your wall.
  • Low cost. Believe it or not, a front projector can be the least expensive alternative for big-screen video in your home. Some projectors built for dedicated home theaters have now dropped below $1,000, making them much less expensive than flatscreen TVs or rear-projection TVs. They can even be cheaper than a regular 36″ television. Of course, projectors range in price from very cheap to very expensive depending on a variety of performance factors. But even some of the best ones are now mass-market consumer products and much more affordable than they used to be. And measured on a cost per diagonal inch basis, they are clearly the least expensive video products on the market.
  • Space-saving. A small projector that is mounted on a coffee table, a rear shelf or bookcase, or mounted on a ceiling, takes up no floor space in the room. When not operating, it is largely invisible. Using a projector gets rid of the big box television that really doesn’t look very good in the room when it is not being used.
  • Easy to install. The ease of installation can vary actually. But if you are setting up a simple system on a coffee table or a rear bookshelf and shining it onto a white wall, it really is as easy to set up as a simple television. They are lightweight, and one person can pull it out of the box, hook it up and get a picture on the wall with little trouble. Sometimes some adjustments are required to fine-tune the picture so that it looks its best, but that is true of all video products including conventional televisions.
  • Eye Comfort. It is the most important thing when it comes to watching anything. Everybody acknowledges that it is always easier to read bigger letters than smaller letters, even if you have the best vision possible. Compared to televisions, the projectors have the luxury of large screen sizes. Because more giant letters are easier to read, it is naturally more comfortable to see a larger screen on the retina rather than a small screen. Screen size is one fact that influences eye comfort. Another advantage of looking at projector images is that it feels more comfortable for your eyes. It is more convenient because the projector uses reflected light to show images. This is in contrast to televisions, which use emitted light.


When you are planning to buy a projector, you need to consider your specific goals or applications and the price that you can afford. Mainly, determining your budget is the best bet to buy a project. Also, you can adjust things according to your requirements, whether you need a low-latency projector for online first-person shooter gaming purposes or you are willing to torrent for a particular type of projector. Your personal preferences and financial circumstances should work to get you the right projector.
