DLP or LCD, WUXGA or Full HD, ANSI lumens and contrast ratio, and then Lens Shift. In the joyful land of video projectors, it is sometimes difficult to find your way around so many are spoiled for choice. In order to help you buy a video projector adapted to your needs, we give you the keys to understand the essentials of the new technologies developed in 2020.
First, determine how and for what purpose you want to use your projector. This will allow you to refine your search using selection criteria suited to the projection environment and the field of application. Generally speaking, we differentiate video projectors for private use, for example in your living room, or for rather professional use, such as in a meeting room.
How is the brightness of the place of use of the projector?
Contrast ratio is a term used to express the maximum difference in brightness between the black color and the white color of an image. Taking the example of a contrast ratio of 1000: 1, this means that the brightest point is a thousand times brighter than the darkest point. The higher the contrast ratio of a video projector, the sharper and more natural the image is projected.
It is the use you will have with the projector and the brightness of the projection environment that will define whether you need a high or low contrast ratio. Opt for high contrast in the context of a home theater installation in order to obtain a deep black. In addition, high-contrast video projectors are preferred in dark rooms because the color rendering is much livelier and much more precise.
On the other hand, the contrast ratio plays a secondary role in the choice of the video projector on rent in Noida if you prefer to use it in broad daylight or in an artificially lit room.
Depending on the operating environment, the options required to install the projector may differ. Please find below the few options that will facilitate the use of the projector:
- Two types of zoom to ensure the great flexibility of home cinema projectors
- Useful for covering the presentation surface, even without the optimal distance
- Moving the image vertically and horizontally without the need to tilt the projector
- Useful when the video projector cannot be placed in the center in front of the presentation surface
- Also called trapezoid correction (Avoids trapezoidal distortion)
- Press the Keystone button on the top of the projector until the keystone distortion is compensated.
- Useful for correcting oblique presentations and straightening the image

Check the types of connection ports in the Projector
Think carefully about the devices that will be connected to your projector to define which connection ports are required. In general, a distinction is made between analog and digital connectivity.
Analog connections include VGA, S-Video, and Composite Video. Nowadays, this type of analog connection is losing ground, apart from the VGA still used, to the benefit of digital connectivity, which has become the norm. HDMI and DVI are therefore considered to be very good standards. Consider at least one of these fittings for each purchase so that you can read current formats.
