Projectors are devices that help to display images or moving pictures (videos) or even slides on the wall or screen. These projectors are mainly used in schools, colleges, and companies to give a demonstration for people in massive numbers. On the account, projectors are becoming more important as people are using it as a home theatre as well.
But while choosing projectors or home theaters, it will be very confusing because of the technical terms that they use. So to make it very simple, I have simplified those terms for you. I’m sure at the end of this article you will get to know about the technologies and you will choose the right projector for your needs.
In the market, there are lots of famous projectors are available like ViewSonic, Optoma, and BenQ. But before buying projectors you have to consider some of the major things as discussed below. Though we have various projectors in the market, having some research about projector will have
5 Things that you have to be considered before buying projectors or home theaters
If you want to learn about projectors and the technologies used in it. Read these 5 must things to buy a projector of your own.
1. Room Size
In projectors, there are two types namely,
Short throw projector
LONG THROW PROJECTORS provides larger images. This is used in auditorium, huge halls etc., This can be attached only on the ceilings. So when you choose Long throw projectors, the screen width must be 100 or 120 inches or even more than that. And the projector must be placed 13 or 14 feet height.
SHORT-THROW PROJECTORS can be attached to the ceiling or else it can be placed on a table. Easy to carry. These Short throw projectors are kept 3 to 8 feet distance from the screen.
And this is calculated with the Throw ration measurement. The throw ratio is the distance between the Screen and the Projector.
How to identify if its Long-throw or Short- throw projector?
To identify the projectors, look at the throw ratio in the manual or box.
Long-throw projector: 1 or above.
Short-throw projectors: 0.6 to 0.8.
Ultra Short-throw projector: 0.4 or less.
2. Projector Type
Next, let us see the projector types. That is the technology that projectors are made of. We have three major types of projectors,
DLP (Digital Light Processing)
LCD (Light- Crystal Display)
LED (Light-emitting diode)
1. DLP Technology (Digital Light Processing)
DLP uses millions of micro scoping mirrors to generate an image. Let us see the Pros and Cons of the DLP projectors.
Display Sharp Images
It doesn’t need any filters
Better response Time
It can project 3D images as well.
As it uses micro scoping images, it use less space.
Color ghosting images (rainbow effect)
Lamp life (2,000 -5,000 hours)
2. LCD (Light Crystal Display)
It uses Liquid crystal displays, so there are no moving parts are involved while displaying images on the screen. Single-chip LCDs are the most basic type of LCD projectors and it is inexpensive. Whereas the 3 chip LCDs are expensive.
It gives better color saturation
Lower noise levels
Better for movies and entertainment.
Less contrast display
Constant filter maintenance
3. LED (Light- emitting diode)
LED technology uses physical light emitting diodes.
Consumes less power
Produce less heat
Has impressive contrast ration
Long lifespan (20,000 hours)
Limited Brightness ( Can’t be used in the rooms with brighter ambient lights)
Resolution is one of the most important parts that we have to know before buying a projector.
There are two things that you have to keep in mind while selecting projectors with the resolution.
If you are buying projectors for home theater, then choose 1920 X 1080px. That is the full HD resolution.
If you are searching for a business, then choose projectors with 1920 X 1200, 3840 x 2160 or, 4K (4096 x 2160) 4K resolution projectors.
Resolution and Brightness plays a major role in projectors. The brightness is calculated according to the Lumens present in the projector. This is really a tedious job, cause some projectors may be good in resolution but the (ANSI) Lumens capacity may be lower. So we have to be very careful while choosing. Let me give you an example to make it clear. For this, I’m going to take BenQ projectors.
Xiaomi Mijia I love this projector for its unique design and easy handling. First I was unaware of this projector and later on, after surfing through net, I came across this projector. Xiaomi products are different from others. So I prefer this projector. As I said unique, this projector has an Intelligent cooling system with a smart silent fan that other projectors don’t have. Once I saw a video about Xiaomi Mijia, that was really impressive. The video was projecting in one particular building and he projected it through the window to the next building wall. The video was so clear and it was not broken. So, that was the reason why I choose this as first.
Best for presentations and you can use it as a home theatre as well.
Projector Type: DLP Display
Resolution: 1920 X 1080 and supports 4K resolution as well.
When talking about Epson PowerLite 3LCD I loved its slim body and the technology that delivers up to 3 times wider color gamut and brightness. It is also a wireless projector that is easily controllable.
Best for Business Travellers as it weighs only 4lbs.
BenQ MX731 4000lm XGA while comparing this projector with other projectors it has a very good brightness with high ambient light. This is very good for the living room and great for business as well. Good for boardrooms and you can accommodate up to 40 participants.
The Epson Home Cinema 2040 3D 1080p 3LCD Projector: while talking about this projector, it has high-quality 2D and 3D images. It is best for gaming, and it is bright enough to stand up to ambient light in a family room. Many people have reviewed it as one of the best projectors for playing games with friends and family. It is good as a Home theatre.

The Sony VPL-VW295ES offers Motion flow for smooth and clear motion, even when viewing 4K content. Motionflow adds frames to reduce blur while maintaining brightness, making it ideal for fast-moving sports content. It gives a true theatre experience with Threatre mode.
The BenQ TK800M is a 4K HDR projector with high brightness for gaming or watching content with ambient light in the room. Its display pretty good even when the curtains are open, but you have to keep the screen out of direct sunlight.
