Before you take a new projector on rent, you should find out about the variants available on the market. Not only the renting price can be quite different, the technology used and the output quality also differs quite a bit with the different models. That is why there is a small introduction to projector technology here and I will go over the most important points to consider when taking a projector on rent in Delhi.
Projector Technology
On the one hand, there are several different display methods. The most common are the LCD projectors. These liquid crystal projectors are aligned with mirrors so that the 3 primary colors are optimally displayed together. In high-quality projectors, there is a fourth LCD panel, which ensures even higher quality and better brightness. The sophisticated technology means that LCD projectors are relatively inexpensive.
- DLP projectors are an interesting alternative and are based on a sophisticated technology that uses a tiny mirror for each pixel.
- DLP projectors have a few advantages, such as better contrast and less drag, but DLP projectors suffer from comparatively poorer color intensity and higher noise levels.
- Newer LED projectors not only have higher energy efficiency, but the light-emitting diodes also hold many times more than conventional projector lamps.
- The quality of LED projectors is good to very good, but the light output is lower than that of the other types presented.
- The fairly new LCoS projectors also use liquid crystal panels and represent a combination of LCD and DLP projectors.
- LCoS projectors offer a sharper picture and higher contrast, but also suffer from a little dragging and an image quality that deteriorates over time.
Resolution
There are different quality levels here. Today, however, only 2 resolutions are really relevant. On the one hand, there are the HD Ready projectors, which can display 720 picture lines. For higher demands there are also the Full HD projectors, which display 1080 picture lines. The quality of the source material (e.g. Blu-ray or DVD) plays an important role in choosing the right projector resolution.
Brightness
Another important aspect is the brightness. Depending on the distance to the screen, the size of the projection surface and the ambient brightness, this plays a more or less globe role.
Today’s projectors usually have between 1,000 and 4,000 lumens, whereby the actual brightness depends on the image settings and the age of the projector lamp. The older it is, the less luminosity it has. The farther away the projector on rent in Delhi should be and the brighter it is in the room in question, the more important a higher number of lumens is.
Contrast
The contrast defines the maximum difference in brightness between white and black. The higher the contrast, the sharper and more natural the picture. In addition, the picture appears brighter and clearer. If the contrast is lower, the black looks more like dark gray. Strangely enough, a lighter environment has a positive effect here, making the black appear darker. With current beamers, there is a wide range of contrast values and how important the contrast is depends on the intended application.
