Are Portable Projectors Affected By Distance?

The goal of this article is to inform you about the not so obvious factor that affects the picture quality of your portable projector. Don’t know what are mini projectors? They are the miniature versions of the old bulky projectors. To know more about them, you may read mini projector reviews. They render the portability that most users are looking for, like the Optoma DX-609 XGA that brings brilliant colors on your screen.

 

Going back to the factor that affects the projection quality of the pocket projectors, one of the most important specification that buyers should be considering when buying a micro projectors is its brightness. This brightness is measured in lumens. The higher the lumen level, the brighter and clearer the images will be. And in dark rooms, high lumens will make images more clearer.

 

And ofcourse the screen distance will also affect the brightness of you Pico projectors. This is the not so obvious part. Eventhough you have high lumens projector rating the distance factor is important. And pocket projector brightness can vary by 200%. Distance will most likely vary depending on setup making it an important factor. The position of the projector and lens type truly affects brightness. And if you give importance to this factors, you can achieve optimal levels of brightness.

 

The brightness varies on lens mode. The amount of light in a full wide angle mode is maximized. And light decreases in a telephoto mode. In other words, the closer your pocket projector to the screen, the more lumens you will be getting. But for portable projectors with limited zoom lens distance is not a problem. But for those with zoom ratios of around 2:1, its distance can largely affect image quality.

 

The large zoom ratio gives you the freedom to choose where to put your portable projector, but is affected by the distance factor. While the nearer the pocket projector the higher the lumens, too near also reduces the picture quality.

 

So keep in mind that not only design matters, but also the brightness that is affected by the distance factor .
