Projectors: Everything You Need To Know

Video projectors are tools capable of transmitting an image or video received from a source, such as a PC, notebook, smartphone, and so on, enlarging it and projecting it on a larger surface.

The example that immediately springs to mind when talking about these products is the cinema projector.

Even if compared to the household ones, it is much larger and more complex.

Some consumers prefer, compared to the use of a normal television, to opt for a video projector for watching movies, TV series, video games or any type of multimedia content aimed at entertainment.

The reason is very simple, although the quality is rarely equal to what is available through a latest generation TV, you can get a much larger image, visible even from a distance.

It is therefore an excellent solution for all those who have an enormous living room.

Resolution and technical characteristics

When you are preparing to buy a video projector you have to consider many factors, first the intended use.

These devices, in fact, have very different characteristics based on the use you will make of them.

For those who want to enjoy films projected on a 100-inch white cloth, it would be better to choose a device that does not involve loss of quality, while, for a presentation in the office, this factor takes a back seat.

However, there are also some areas where no compromises can be made, such as, for example, in preparing large events or installations in museums where quality projections are required.

So how to choose the right projector for your needs? Let’s see the crucial elements together.

Resolution is definitely a great place to start. As the most technological will know today, the quality standards of the images refer mainly to the acronym HD, or High Definition.

The most used resolutions today are HD Ready, that is 1,280 x 720 pixels, Full HD, 1,920 x 1,080 pixels and finally the most recent Ultra HD, which is often referred to with the term 4K because we are talking about a resolution of 3,840 x 2,160 pixels. .

Projectors can fall into one of these three bands, resulting in an exponential price increase as you move up to a better resolution.

Before opting for a device that supports support for one of these, remember that “native resolution” and “maximum” resolution are two very different things. Many projectors on the market guarantee you a high maximum resolution, usually Full HD.

In reality, however, this term refers to the input it can receive. The projected image will have a resolution equal to that showed as “native”.

So pay close attention and carefully analyze the data sheet to understand the true ultimate definition.


Another detail not to be underestimated is the brightness of the image.

The projectors are in fact equipped with a lamp which, with its beam of light, transmits the image onto a white wall or a cloth. The term for brightness is “lumen”.

The higher this value, the better you will see the image in lighted environments.

A projector equipped with 500 lumens, for example, will need a completely dark room to return a clearly visible image, thus proving not suitable for the office or for university presentations.

If you have to use it only at home, it could still be satisfactory even if the value we recommend is at least 2,000 lumens.

Instead, a different speech must be made for what are defined ANSI lumens.

The acronym ANSI stands for American National Standards Institute and refers to a measurement carried out by the North American body.

Headlamps bearing this item are usually brighter for the same value.

Dimensions and weight

While on the one hand they are factors that those who have to install the projector at home should not consider too much, unless you have little space, they are instead crucial for those who must always carry it with them, perhaps to work, university or school. Or just for entertainment at a friend’s house.

On the market you can find very compact mini projectors ( Check here the list of the best offers) that can be carried in your bag or backpack with no problem, with a low weight that sometimes does not even reach a kilogram.

But what are the real benefits from a qualitative point of view?

The problem is precisely this, by sacrificing space you cannot have a high video quality, much less a satisfactory lumen value.

So be very careful if besides the simplicity of transport, you are also aiming for a quality that reaches at least 800 x 480 pixels.


Projectors fall into different price ranges, just like all technological devices.

The lowest does not reach 100 euros, so do not expect miracles from these devices that usually have a native resolution that is around 800 x 480 pixels.

The next one oscillates between 200 and 400 euros, offering an important technological leap, sometimes even with native Full HD resolution, sacrificing a little the lumen value.

Finally, projectors that exceed $ 1,000 are still few and not all of them are worth the money.

Among these are those capable of projecting images in 4K, indispensable if you love to see movies at the highest resolution currently available.
