What to look for when buying a projector? Infographic

Last Updated on January 21, 2021 by Righteous Daddy (Rehan)

Choosing the right projector can be overwhelming nowadays. You need to consider many factors before purchasing the projector you want. I have created this infographic buyer’s guide to help you choose the best projector for you.

Let’s get started.


First, you need to determine your budget. See, I can recommend you many projectors, but if it is not in your budget, what is the benefit of that? So, first, set the price range you are willing to spend on the projector. And then move to the next step.


Once you have determined the budget, you need to know for what purpose you are buying the projector. If your objective is total entertainment, then choosing the home cinema projector is your best choice. If you want to have a projector for business, then a business projector is your best bet.

To narrow it down more, you have to understand your surroundings. Suppose your purpose is to play games, then getting the best projector for video games would be your goal. However, if you have a small room and want a projector, you need to get the best projector for a small space. The short-throw projectors are designed for small rooms. So, you need to get the one.


You have to understand the importance of the location where you are going to use the projector. For instance, you want a projector for a bright room. You need a projector capable of working in the ambient lighting.

In short, get the projector that suits the room setting. Using a projector designed for the darkroom using it in the bright room will surely give you an unsatisfactory result.


The brightness of the projector is calculated in the lumens. The higher the lumens, the more it will be suitable for bright settings. The projectors with lower lumens are designed for a darkroom and less lighting places. However, if you want the best projector for a bright room. You need to have the one that offers the most lumens. The sweet spots are 3000 lumens and beyond.

Contrast ratio

To simply put, the contrast ratio is the difference between white and black. Suppose the projector you are getting has the 150,000:1 the 150,000 here is the white image luminousness, and 1 represents the black imagery. However, the contrast ratio can be affected by external factors like lighting, open windows, etc. So, no matter the contrast ratio, if the location is not right, the projection will be dull.  The higher the contrast ratio, the brighter and sharper will be the image quality.

Throw Distance

There are different throw projectors. Short throw, medium throw, and large throw are the most common names you may have read around the internet. I am not going to get into technical details as the article is not for that purpose. As you are shopping for the projector, you will come across the throw types of projectors. If you see short-throw or ultra-short-throw, it means that this projector is suitable for small spaces.

The medium throw projector can be used in medium places, and the large throw projectors are designed for larger rooms. However, that is not true every time. Basically, the throw distance is the projector distance for the projection screen. Suppose you have a small room. The projector says it has 4 inches throw distance. At least you can use that projector 4 inches away from the projector screen.

To clarify it further, it is a distance between the screen and the projector. You can use a throw distance calculator to determine the ideal distance.

Display Type

Nowadays, projectors come with three types of display technology. The most common and famous is DLP (digital light processing). The second one is LCD (liquid crystal display), and the third one is Lcos technology. Lcos is like a hybrid that offers both DLP and LCD combination and has a more sharp image and display quality. However, The Lcos projectors are expensive.

So which projector should I choose?

It depends on your own preference. The DLP projectors are suitable for high contrast and smooth motion projection. In contrast, LCD projectors offer sharper images for data presentation and slides. The LCD projectors are superior to DLP projectors in the well-lit room.

Source of the light

The three primary sources of light are a lamp, laser, and LED. The lamps have an average life of 3000 to 4000 hours. Standard lamps need to be replaced more frequently. In contrast, Laser technology requires no replacement. And LED light sources are more potent than traditional lamps. The LED bulb can last to 20,000 hours on average.


The resolution of the projector tells you that it is capable of achieving the native resolution. Suppose the Full HD projector will have a maximum resolution of 1920 x 1080. You cannot attain more resolution than the Full HD, even though the projection screen can support up to 4k.

Wrapping it up…

I have stated all the major factors you need to look for when shopping for a projector. If you like the buyer’s guide, I have created it for you. Please share it with others. And the infographic I know is not perfect, but I am the sole person, and I did my best to make the one easier. I hope this guide will assist you in choosing the best projector.
