  • Projection Technology

    This is the way in which the light from the projector lamp is transformed into an image to be projected onto a surface.

    DLP (DMD)

    In this technology (Digital Light Processing), which is the most widespread, the image is created by a chip with microscopic mirrors and a rotating colored disc. The chip is called DMD (Digital Micromirror Device).

  • Native Resolution

    This refers to the number of pixels in which the projected image is divided horizontally and vertically. The more pixels, the higher and better the resolution. They are classified from lowest to highest resolution as follows: HD, Full HD, 4K Ultra HD.

Throw Ratio
0.496 :1

Throw Ratio

The throw ratio or projection distance ratio indicates the width of the image produced by the projector when placed at a specific distance from the screen.

2. For example, a throw ratio of 1.3:1 means that the image will have a width of 1 meter when the projector is placed at a distance of 1.3 meters from the screen.
Contrast
3000000 :1

Contrast

Contrast refers to the difference between the brightest and darkest points of an image. It is measured as a ratio, e.g., 3000:1, where a higher ratio means deeper blacks and more vibrant colors, thus improving image quality.
