The contrast control on a display adjusts the range for the difference between white and black. Increasing the contrast makes the whites brighter and the blacks darker, enhancing the overall clarity and sharpness of the image. Proper contrast settings are vital for ensuring that the image displayed is visually appealing and easy to interpret, especially in varying lighting conditions.

When a client requests an addition to the project that wasn't included in the original scope, such as a videoconferencing system, a Request for Change (RFC) is needed. An RFC formally documents the change in scope, budget, or timeline and ensures that all parties agree to the modifications.

CTS Technology Specialist Reference

The CTS guidelines discuss the use of RFCs to manage scope changes, helping avoid misunderstandings and ensuring all modifications are approved and documented.

Ultra High Definition (UHD) resolution is defined as 3840 x 2160 pixels. This resolution is commonly referred to as 4K UHD and provides four times the resolution of Full HD (1920 x 1080 pixels). UHD offers greater detail, clarity, and overall image quality, making it suitable for large displays and high-definition content.

The images shown represent keystone distortion, which occurs when a projector is not aligned perpendicularly to the screen. This misalignment results in a trapezoidal image rather than a rectangular one.

According to the AVIXA CTS Exam Guide, keystone distortion is covered under the Display Systems section, which states:

“Keystone distortion happens when the projector lens is not perpendicular to the screen plane, often due to improper vertical or horizontal positioning. The image appears wider at one end and narrower at the opposite, forming a shape like a keystone — hence the name.”

This distortion is not related to contrast (A), which refers to the difference between light and dark elements in an image, nor chromatic (B), which pertains to color distortion or aberration. While the shapes resemble trapezoids, trapezoid (D) is a description of the resulting shape, not the distortion type. The technical term for this specific distortion is keystone.
