We know how difficult it can be to choose a video projector … Sometimes the buyer feels lost and does not know how to evaluate the right video projector for his space!

Nowadays there is a lot of supply, which makes the decision complicated. Today we are going to help you learn to see what features are necessary to analyze in a projector to quickly become ideal in your room.

First, we must answer the following questions:

  • How much space is available to place the projector?
  • What is the lighting of the space?
  • What is the purpose of the projector?

These questions influence a lot when choosing!

Brightness, Contrast and Resolution

The projector uses a light lock to display the content. Therefore, it is necessary that it has a good light, especially for environments with lots of light. This characteristic is measured in lumens.

Models from 1,500 to 3,000 lumens require that the environment be quite dark and that the distance between the projector and the wall be shorter.

Projectors with more than 3,000 lumens do not require a low light environment.


A projector whose purpose is to display films and games, opt for higher settings. Full HD (1920 x 1080) and WUXGA (1920 x 1200) models are best, but HD (1280 x 720) and WXGA (1280 x 800 pixels) resolutions may also be good options, especially in dark rooms.

The size of the image depends on the distance from the projector to the surface on which the image will be projected. Thus, the greater the distance, the larger the image. However, as the brightness proportionally decreases the distance, the farther the projector is, the lower the brightness.

Contrast Ratio

   It is recommended to check the contrast ratio: the higher it is, the better. The ideal is to choose a projector with a contrast of at least 500: 1 – which means that white is 500 times lighter than black. The higher this rate, the greater the color variation and the amount of detail. The projector’s resolution is measured in pixels and the higher it is, the clearer and more defined the image will be. A resolution of 800 x 600, for example, despite being low, may be sufficient to display slides. More detailed images require higher resolution.


In this topic it is important to pay attention to the outputs of the equipment that will work together with the projector. Nowadays most computers have VGA and HDMI connectivity, so it is important that the projector also has these inputs. If the idea is to make projections of the tablet or smartphone, give preference to models with wireless connectivity, example: Bluetooth.


   If you don’t want to leave your projector fixed in one place, aiming to transport it whenever you need to give speeches or presentations at companies, for example, you need to keep in mind that you need to buy a portable projector.There are also video projectors that work on batteries, without the need for plugs to work, which helps in portability and application. In addition to the equipment being more compact and easy to use, it must also contain a case or bag that facilitates movement without causing external damage such as scratches and scratches, or internal, such as the movement of parts.


Spending less electricity is beneficial not only because it spends less money, but also because it preserves the environment. There are projector models that automatically adapt the brightness of the projected image, according to the lighting of the place. Thus, if there is no need for such strong lighting, the brightness will be reduced, using less electricity. Choosing a projector with an LED lamp will also be a way to save money, not only because the lamps are more durable, but also because the consumption of electricity is much lower.


We hope we were able to help a little when deciding which video projector is best suited to your space. If you still have doubts, Sonopro has engineers with the right knowledge available to assist you … Contact us!
