Most modern projectors come with keystone correction, which can be adjusted manually or automatically. However, the effectiveness of keystone correction depends on the projector’s capabilities and the severity of the angle.
Types of Keystone Correction
There are two types of keystone correction:
- Vertical keystone correction: This type of correction adjusts the image to compensate for vertical angles, such as when the projector is mounted above or below the screen.
- Horizontal keystone correction: This type of correction adjusts the image to compensate for horizontal angles, such as when the projector is mounted off-center.
Some projectors also offer a combination of both vertical and horizontal keystone correction, which provides more flexibility in terms of mounting options.
The Effects of Angled Projection on Image Quality
While keystone correction can help to compensate for angled projection, it’s not a perfect solution. Angled projection can still affect image quality in several ways:
- Geometric distortion: Angled projection can cause the image to become distorted, with straight lines appearing curved or bent.
- Focus issues: Angled projection can make it challenging to achieve a sharp focus, especially if the projector is not designed for angled mounting.
- Color uniformity: Angled projection can affect the color uniformity of the image, with some areas appearing brighter or darker than others.
To minimize these effects, it’s essential to choose a projector that is designed for angled mounting and to follow the manufacturer’s guidelines for keystone correction.
Projector Specifications to Consider
When selecting a projector for angled mounting, there are several specifications to consider:
- Lens shift: Look for projectors with a wide lens shift range, which allows for more flexibility in terms of mounting options.
