Correct Answer:
B
* B. Correct the keystone:
A keystone correction adjusts the image shape when a projector is angled either up or
down. When a projector is not positioned directly perpendicular to the screen, the image becomes distorted or offset. Correcting the keystone will resolve alignment issues, ensuring that the presentation matches the display.
Incorrect Options:
* A. Adjust the color settings: This is used for improving color balance and has no impact on ghosting or mismatched images.
* C. Increase the brightness levels: Brightness changes the visibility of the image but does not address ghosting or alignment.
* D. Replace the monitor: Replacing the monitor is unnecessary unless there is hardware failure, which is not indicated here.
Key Takeaway: Keystone correction is essential to resolve alignment and distortion issues in projected images.
