Today it is difficult to present a report or a conference without any kind of graphs or visual tables. And in schools now many classes are equipped with projectors. Select a small portable projector for presentations is not so simple, because there are a lot of models and each has its advantages.
Selecting a Portable Multimedia Projector
So, you have set yourself the task of finding a compact and convenient projector for work or entertainment. We will take into account the main parameters: resolution, lens characteristics, light flux.
As for the resolution, it directly depends on the signal source. It is important that the resolution of the source coincides with the resolution of the projector itself. That's why some gadgets have to be supplemented only with special models. For example, there is a portable projector for smartphones , which is synchronized with this device. Synchronization of the portable projector for smartphones takes place using a special application. Some models are equipped with even cameras and speakers so that you can conduct video conferences. But most models are designed specifically for computers. The most commonly purchased with a resolution of 1024x768, less often there are 800x600.
The picture quality of the portable projector depends on the amount of light flow. The brighter the lighting in the room, the more there should be a light stream. But in any case, the effect of the light source on the projector itself should be excluded immediately.
Portable projector for presentations - laser or LED?
In a portable LED projector, instead of the usual heated incandescent lamp, a new version is used - an LED light emitter. The very principle of design allows you to create not just convenient portable devices, but quite tiny in size almost with a phone or tablet. It is also important to note that such a device consumes very little energy, and therefore can work even on battery power. A portable laser projector is an option for entertainment rather than for work. In principle, its device is very similar to a manual laser pointer. This projector is often chosen for recreation in restaurants or discos. As a rule, in all models there are three modes: starry sky, beam and rotation.
