Things to Consider When Buying Short-Throw Projectors

It is easy to buy a projector. But are you sure you get a good one? Before buying one, you have a lot to consider – things that affect the device’s performance. Below are some of the most important factors to keep in mind in getting the right short-throw projector.

Brightness

Every projector also has a different brightness. Note that some projectors work well in bright background while others do well in the dark. Thus, consider the environment where you will be using it when choosing a projector.

Choose projectors with low brightness in a dark environment. Projectors with high brightness are best for bright environments. For video content, choose ones with over 3000 lumens. Below 1500 lumens are great if your room has limited lighting.

Display Technology

Every projector has different technology used, which makes it bad or good depending on the use. Some of the standard technologies used in projectors are LCD, DLP, LED, and others. They work differently and produce varying quality of images.

Note that those with DLP technology have some rainbow effect because of their many moving parts. LCD, on the other hand, is more reliable and doesn’t have that rainbow effect. On that note, choose the projector with the kind of technology you want.

Native Resolution

Make sure that before you buy a short-throw projector, its resolution works with the kind of content you want to project. High resolution is best for when you want to use the projector for movies and gaming.

For business and school, low-resolution ones are good enough. As mentioned above, there are great types of short-throw projectors with high resolutions. They are certainly an excellent choice for both home theater and business use.

Screen Size

Like any other projector, a short-throw one needs a specific type of screen to work well. The size is particularly crucial since the quality of images you want to see mostly depends on it. Make sure that your screen is compatible before buying a short-throw projector.

Portability

One of the most important factors most people look for in a projector these days is portability. It’s great to be able to carry it around and install it in any position you want. Of course, it depends on your preferences.

If you plan to use the projector for school and business, you might want a portable projector. On the other hand, you likely don’t need a portable projector if you plan to use it at home.

Contrast Ratio

You can tell the whitest level and blackest level of the contents the projector displays on the screen from its contrast ratio. A higher contrast ratio means clearer pictures and contents, although it is unreliable compared to screen quality and lighting.

Throw Ratio

Since we are talking about short-throw projectors, you already know this one comes with a short-throw ratio. But there are also others like long-throw projectors and ultra-short-throw projectors. With that said, understand what suits your needs.

Budget

Of course, it is crucial to consider your budget since a projector is a considerable investment, no matter how inexpensive they are now. As people say, you always get what you pay for, which means you cannot trust super cheap projectors.

The good ones can go as low as $300, but the best for home theaters are mostly higher priced. You can sometimes find rare cheap projectors that suit entertainment purposes. Make sure to look around first before buying anything.
