How to choose a good projector?

When we decide to buy a projector is because we want to improve our video experience and therefore we seek the one that gives us the best performance. The characteristics that we offer the projectors are becoming bigger and something more impressive that is why we have compiled to the most attention we must lend:

ANSI Lumens

In the projectors the lumens are used to be able to measure the power of the projector, that is, its brightness, the amount of light that it is able to emit. The greater the number of lumens the greater the power will have the focus to project the image. This power has nothing to do with the quality of the image that will depend exclusively on your technology. We must also take into account the room where we are going to use the projector as the lumens also determine, in most cases, the price of the projector. These lumens are determined by a standard marked by the National American Institute of Standards (ANSI).

We must also distinguish whether we want a projector for the office or home because the conditions will need some benefits or others.

Domestic use tends to be more dull because we will usually use them to project movies, series or events and we will do so with a much lower ambient light than we would need for an office that would be in broad daylight.

Therefore, a House will not need a projector with so many lumens of power and the projector would be perfect we could consider it from 2,000 lumens of power so that we can enjoy both in a room totally in the dark, as in a space with something more than L UZ environment.


What does the contrast mean? The contrast conditions the depth of the blacks and the brightness of the colors, that is to say, is the difference between the most intense white and the purest black. Technologies are increasingly improving whites and blacks by making a greater difference so that we can appreciate the details with good depth.

There must be a balance between the lumens and the contrast ratio because if we have a projector with many lumens and a contrast ratio under the image will be poor and without color. Native levels from 2000:1 are ideal for projections at home, this means that the clearest point is 2,000 times lighter than the darkest point.


LCD projectors: They’re much simpler. The lamp’s white light is divided into the three primary RGB colors and passes through three LCD screens. This creates a recognizable color image. The colors are vivid, natural and high quality. These projectors usually have a life in their lamps between about 2,000 and 4,000 hours. They are usually the most employed at home.

You may find few good quality projectors guide for the money, here.


DLP projectors: These projectors require less maintenance by not having filters to be cleaned and use millions of small mirrors to project the colors on the screen. Thanks to the fine mirror structure, the image display is very thin and no dots are visible in the image.  They have a longer lifespan and the native contrast is greater. For its manufacture, materials are used to ensure the optimum performance of the projector, providing a clear difference between brightness and contrast. Which gives rise to a “real image “.


The resolution is a very important factor for a projector because it will allow us to see the images with a better or worse definition. The resolution is the number of pixels in the horizontal and vertical lines that a screen can display. At less resolution less pixel quantity and therefore worse quality. There are different types of resolutions:

-Full HD: This is a resolution of 1,920 x 1,080 pixels with a total of 2,073,600 pixels on screen

-UHD: This is a resolution of 3,840 x 2,160 pixels with a total of 8,294,400 pixels on screen

-4k: This is a resolution of 4,096 x 2,160 pixels with a total of 8,847,360 pixels on screen

These are the most common and demanded resolutions currently on the market, but we will also have to take into account the size of our screen to choose the most suitable.


We cannot forget, nor obviate, the connections that our projector has because they are an important factor to opt for one or the other. This technology will allow us to connect it to a greater number of devices and in a more or less simple way.

The usual connections are HDMI, S-video, VGA that will facilitate the connection of laptops and mobiles. If they also include USB ports or card readers we will make the connection much simpler and without cabling. Digital connections are always more advisable than analogues because digitals will allow the transmission of audio and video as well as ensuring better quality.

Now, even, we can find in the projectors WiFi connection and functions of the Smart TV as in the projector Benq 11000

Focus Distance

Is the distance that we will have to place the projector to play the image. There are projectors that incorporate a shooting calculator and adapt their zoom depending on the screen that we want to project the image. Projectors like the W1700 of Benq make these modifications automatically


That projectors offer us other possibilities at the level of accessibility and facilities is a point in favor. That includes the remote control and the brackets to be able to place it on the ceiling are options that always come in very well and more when what we want is a home theater.

Typically, the Benq range meets all of these features. Any projector you choose will meet these standards giving the best imagined video experience.
