Things to Consider Before Buying Best Mini Projectors
There are some basic features to consider, to understand which mini projector to buy: resolution, brightness, weight and size, durability and connectivity.
However, all this information will be useless if you do not have a clear idea of where and where you will use your purchase.
To make an informed choice, one should also know the environment in which the portable projector will be placed. In particular, the following can be decisive:
1. The surface on which we intend to project. Good quality screens better support the brightness of the image, compared to an opaque and perhaps not entirely white wall.
2. How far from the screen or wall the projector will be located. The further you go, the more you can enlarge the image until you explore the maximum diagonal allowed by the projector. A larger image, however, also needs a higher resolution to stay sharp.
3. In what position will the projector be concerning the illuminated surface (front, rear, side …). The headlamps have a trapezoidal correction function, which adjusts any distortions, but with some limitations.
Those looking for a mini projector, however, could use it on the go or take it with them to different places for professional presentations. So the best mini projector in our opinion is, in a word, the most “flexible”.
Dark in The Room
The brightness of the video projector, measured in ANSI lumens, allows you to understand if and how much you can use it in environments where it is not possible to obtain total darkness.
During a presentation in a work context, it is likely that you will have to worry about having images and texts readable even with a certain level of ambient light.
The audience may need to take notes, to interact, to work on keyboards that are not necessarily backlit, not to mention the classrooms.
In this case, it is necessary to choose a model that offers a higher number of lumens.
Unfortunately, the more compact the size of the projector, the higher the likelihood that it won’t hold a powerful lamp.
It is better to be wary of those who advertise 3000 Lumens on projectors as big as a mobile phone, often at the top of the best-selling list, and price below 100 euros. Behind a 5-star review, there may be opaque marketing strategies.
Generally, the threshold within which it is possible to see a projection even in illuminated environments is considered 3000 lumens.
In reality, with some compromise, one can derogate from this rule, but up to a certain point.
Furthermore, it must always be remembered that the power of the light beam weakens as you move away from the screen. So you need to consider at what minimum distance you can fix the projector.
Resolution and Contrast
The resolution, as for the screens of a computer or a TV, measures the maximum pixel density with which images and texts will be proposed, with a difference. In the case of a monitor, it is not possible to vary the projection diagonal, while with a projector it can.
Depending on the distance from the surface on which you intend to project, be it a screen or a wall, you can enlarge the image.
The lower the resolution, the lower the possibility of expanding the picture without noticing a quality deficit.
Images and texts require different resolutions to be considered “readable” and well defined. For writings, it would be better not to drop below the WXGA standard (1280 × 800 pixels).
The images are satisfied even less for an excellent rendering, although, for the projection of films, the ideal resolution is Full HD (1920 × 1080).
On a pocket projector, it is rare and unlikely, but on portable models, however comfortable to carry, it is found.
Then there is the contrast ratio, which identifies the difference in brightness between the lightest and darkest point of the image. If you read 5,000: 1, which is a value below which it would be better not to go down, it means that white is five thousand times brighter than black.
Beware of Decibels
Pay attention also to the values concerning noise. The noise is always produced by the cooling fan, and should not exceed 30 decibels. Of all the parameters, it is one of the most difficult to verify, because the fan activity varies according to the intensity with which the projector is used and the climate in the projection room.
There are specific apps, for those who want, that allows you to measure decibels with your mobile phone, with relatively reliable results. They are always your ear and your tolerance, however, the best yardstick.
Companies are also required to indicate the longevity of their product, i.e. the maximum number of projections expressed in thousands of hours.
It is believed that 15 thousand hours equals one use for 8 hours a day, for five years. This is a value to be taken into significant consideration if you frequently use the projector, for example as a replacement for the TV.
Also, it is advisable to check whether it is possible to replace the internal lamp, which is the element most subject to wear.
