Throw Ratio
When this device is positioned so that the lens surface is perpendicular to the wall, the projected image will appear as a standard rectangle. The relationship between the projection distance and the projected image size is as follows:
Throw Ratio = Projection Distance / Projected Image Width
The HORIZON 30 Series features an optical zoom lens with a Throw Ratio of 1.2:1–1.5:1.
Recommended projection distance (Lens to screen):
Notes
- These Projection distances are estimates for reference only.
- For the best image quality, avoid using the extreme ends of the zoom range whenever possible.
- The Projection Distance refers to the distance from the lens surface to the screen, not the distance from the device's mounting position to the screen.
