What aspect ratio must a projected image conform to if it is going to fill the width of a 1.33:1 screen?

• A. 1.78:1
• B. 4:3
• C. 16:9
• D. 16:10

Answer: (A)

To determine the aspect ratio that conforms to filling the width of a 1.33:1 screen, it is important to understand the relationship between aspect ratios and how they are represented. A 1.33:1 aspect ratio (which is also commonly known as 4:3) indicates that for every 1.33 units of width, there is 1 unit of height. When a projector is set to fill the width of a screen with a 4:3 aspect ratio, it needs to project an image that maintains this ratio. However, 1.78:1 (also known as 16:9) is actually a wider ratio compared to 1.33:1. If you project a 1.78:1 image onto a 4:3 screen, the entire width of the screen will not be filled, leading to letterboxing or black bars on the sides. Therefore, it wouldn't be possible to fill the width of a 1.33:1 screen with a 1.78:1 image correctly. In contrast, a 4:3 image directly fits the dimensions of a 1.33:1 screen, as both represent the same aspect ratio. Images with a 16:9
