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.
