Which screen dimensions would be appropriate for a room with an 80-inch width and a resolution of 1920 x 1080?

The selection of a screen with an image width of 80 inches and a height of 45 inches is appropriate for a room that is 80 inches wide. This choice maximizes the use of available space without exceeding the room's dimensions.

In terms of aspect ratio, the resolution of 1920 x 1080 corresponds to a 16:9 aspect ratio, which is standard for many screens, especially for video content. When applying this aspect ratio to an 80-inch wide screen, the corresponding height can be calculated to maintain the same ratio. With a width of 80 inches, the height should be approximately 45 inches to ensure that the image fits correctly without distortion.

Choosing a screen that fully utilizes the available width of the room ensures that viewers can experience a more immersive viewing experience without any discomfort or obstruction. This size also allows for appropriate viewing distances to be maintained, enhancing visibility and engagement with the screen.

Other options present either dimensions that are too large or too small for the room's width, which could lead to issues with viewing angles, comfort, and screen visibility. This makes option B the most suitable choice for the given environment.
