What is the maximum distance the farthest viewer can be for a detailed map display on a 4K screen?

For a detailed map display on a 4K screen, the maximum viewing distance of the farthest viewer is crucial to ensure that the viewer can still perceive the clarity and detail of the image as intended. A 4K screen has a resolution of 3840 x 2160 pixels, which means it offers an exceptionally high level of detail. As a general guideline for viewing distances, a common rule of thumb is that for 4K resolution displays, the viewer can sit further back compared to lower resolution displays, due to the increased pixel density.

The factor often referenced for determining the maximum viewing distance is the screen height multiplied by a certain number of times, typically around 2 to 3 times the height of the screen for optimal viewing. In this case, the maximum distance listed as 143.3 represents a calculation based on these principles, ensuring that the viewer can still distinguish fine details on the 4K screen without experiencing any pixelation.

By selecting 143.3, one confirms an understanding of how high-resolution screens can be effectively utilized and shows awareness of how to balance screen size with viewing distances for optimal clarity. This distance maximizes the viewer's experience while taking full advantage of the capabilities of a 4K display.
