Certified Technology Specialist (CTS) Practice Exam

When commissioning a video display installation, what technique does the AV technician use to ensure proper functionality?

1. Use color filters to check visual accuracy

2. Confirm brightness, contrast, and color adjustments using SMPTE PLUGE Pattern

3. Utilize a multimeter to measure voltage

4. Test the AV receiver's compatibility with the display

The correct answer is: Confirm brightness, contrast, and color adjustments using SMPTE PLUGE Pattern

The technique of confirming brightness, contrast, and color adjustments using the SMPTE PLUGE Pattern is essential during the commissioning of a video display installation. The SMPTE PLUGE (Society of Motion Picture and Television Engineers - Picture Line Up Generation Equipment) Pattern is specifically designed to help technicians calibrate displays by providing clear visual cues for establishing black levels, ensuring that the display can accurately reproduce the intended colors and images. By using this pattern, the AV technician is able to visually inspect and adjust the display's settings to achieve optimal performance. This involves checking for proper brightness levels, ensuring contrasts are set correctly, and confirming that colors are reproduced accurately— all integral parts of ensuring that the video display functions correctly in a given environment. Proper calibration guarantees that the visuals delivered meet the standards expected for quality viewing experiences, crucial in professional AV settings. The other options, while related to AV installations, do not directly address the need for visual calibration of the display in the same comprehensive manner as the SMPTE PLUGE Pattern does. Color filters can help with understanding color accuracy, but they do not provide a complete assessment of brightness and contrast like the SMPTE pattern. Measuring voltage with a multimeter and testing compatibility with the receiver are important for overall system function
