At what distance from the screen is the farthest viewer viewing detailed content on a 4K image?

To determine the appropriate distance for viewing detailed content on a 4K image, one must consider the resolution of 4K, which is 3840 x 2160 pixels. This high resolution allows for greater detail, enabling viewers to sit closer to the screen without perceiving pixelation.

A common guideline in the audiovisual industry suggests that for optimal viewing of 4K resolution, the ideal distance is approximately 1.5 times the height of the screen. Given a properly sized screen for the resolution and typical room configurations, 120 inches is a distance at which viewers can appreciate the full detail of a 4K image clearly, while still being comfortable.

Therefore, at 120 inches, the farthest viewer can take advantage of the clarity and detail 4K provides. Other distances listed, such as 240 inches or 180 inches, would typically be more suited for lower resolutions, as sitting farther away from a 4K image would not allow the viewer to discern the finer details that the resolution has to offer. Thus, selecting 120 inches aligns with optimal viewing practices for high-resolution content, making it the correct choice for the question regarding the farthest viewer's distance for detailed viewing.
