WUXGA stands for Wide Ultra Extended Graphics Array and has a resolution of 1920 x 1200 pixels. To determine the aspect ratio, we divide the width by the height:

=1.6:1\text{Aspect Ratio} = \frac{1920}{1200} = 1.6:1Aspect Ratio=12001920​=1.6:1

Therefore, the aspect ratio for WUXGA is 1.6:1. This aspect ratio is common for widescreen monitors and provides a wider display format compared to traditional 4:3 screens, enhancing the viewing experience for multimedia content.

The question relates to viewer distance based on image height, which is part of image size and viewing distance calculations under AVIXA design principles.

This screen is 65" diagonal with a 16:9 aspect ratio. The image height is given as 31.6" (80.2 cm).

According to the AVIXA CTS Exam Guide, the formula for minimum (nearest) viewing distance for a basic decision-making (BDM) environment is:

Minimum viewing distance = 1.5 × Image Height

— AVIXA CTS Exam Guide, 5th Edition – Chapter 7: Display Design, p. 155

So in this case:

Image Height = 31.6 inches (80.2 cm)

Nearest Viewing Distance = 1.5 × 31.6 inches = 47.4 inches ≈ 4'8" (1.4 m)

Thus, the correct and closest viewing distance to ensure readability and visual comfort is Option C: 4'8" (1.4 m).

Note: For analytical decision-making (ADM), a shorter distance might be used (up to 4× height), and for passive viewing (PV), longer distances are acceptable. But this question implies nearest (minimum) viewer positioning, hence the 1.5x rule applies.

To mount a projector so that it is horizontally centered with the suspended screen, the technician should look at the reflected ceiling drawings in the plans. Reflected ceiling plans provide a view from above, showing the layout and alignment of ceiling elements, including projectors, screens, lighting, and other fixtures. This perspective is essential for ensuring that the projector is correctly aligned with the screen. Axis Technology Specialist documentation highlights the use of reflected ceiling plans for precise alignment of AV equipment.

A system warranty is provided by the AV integrator and covers the entire installed system, including materials and workmanship, for a specified period post-installation. This ensures that any issues arising from the installation process are addressed without additional cost to the client.

The formula for calculating speaker spacing for 50% coverage (edge-to-center) is:

Spacing = 2 × (H - h) × tan(θ / 2)

Where:

H = ceiling height = 3 m

h = ear height = 1.2 m

θ = coverage angle = 90°

Plugging in the values:

Spacing = 2 × (3 - 1.2) × tan(45°)

Spacing = 2 × 1.8 × 1

Spacing = 3.6 m

Therefore, the correct spacing is 3.6 m (12 ft).

"Shock Loads" for equipment mounts refer to sudden additional loads from earthquakes or personnel hanging from the mounts. Shock loads are unexpected forces that can be significantly higher than normal operating loads and can cause structural failures if not properly accounted for. This is particularly important in areas prone to seismic activity or where equipment might be subjected to additional stresses. Axis Technology Specialist documentation highlights the need to design mounts and supports to withstand such shock loads to ensure the safety and durability of the installation.

The most important information to gather on a site visit when upgrading a camera system in an existing boardroom is the distance from the lens to the first participant. This measurement is crucial for determining the appropriate camera lens and its focal length to ensure all participants are clearly visible within the camera's field of view. It also affects the placement and angle of the camera to achieve the best possible coverage. Axis Technology Specialist documentation emphasizes the importance of precise measurements and placement to optimize camera performance and video quality in boardroom settings.

When a client requests an earlier project completion date, the AV contractor should first issue a Request for Change (RFC). This formal request documents the proposed schedule change and requires client approval. It allows for assessment of resource requirements, timeline adjustments, and any potential cost implications.

CTS Technology Specialist Reference

The CTS guidelines stress documenting changes through formal requests like RFCs to ensure client approval and clarity on any impact to the project.
