Difficulty: EasyVideo, Display, and Projector Issues

A technician connects a workstation to a digital projector in a conference room. The projected display appears trapezoidal, visibly wider at the top than at the bottom. Which of the following settings should the technician adjust to square the image on the screen?

  1. Keystone correctionAnswer
  2. B
    Inverter voltage output
  3. C
    GPU VRAM clock rate
  4. D
    Display cable bandwidth standard

Answer

Adjusting the keystone correction setting on the projector will compensate for the tilt angle and square the image.
Keystone correction is designed specifically to rectify trapezoidal image distortion that occurs when a projector lens is angled relative to the projection surface.

Step-by-Step Solution

1
Analyze the visual symptom reported by the user
The image shape is distorted into a trapezoid (wider at the top).
Trapezoidal distortion occurs when the projection axis is not perpendicular to the screen.
2
Select the built-in control designated for geometric correction
Keystone correction shifts the image geometry digitally to produce a flat rectangular display.
Keystone adjustments directly fix vertical and horizontal angle distortion.
