What is the distance limitation to the Farthest Viewer for an Image Height of 90 inches on a 4K display?

To determine the distance limitation to the farthest viewer for an image height of 90 inches on a 4K display, we can apply the general guideline used in the AV industry. This guideline recommends that the viewing distance should be a certain multiple of the image height.

For 4K resolution displays, the recommended maximum viewing distance is typically around 2.5 to 3 times the height of the display. By using an image height of 90 inches, we can calculate the farthest distance by multiplying 90 by a factor that fits within the standard range.

Applying the factor of 2.5 to 3, you get:

• 90 inches x 2.5 = 225 inches

• 90 inches x 3 = 270 inches

The farthest viewer distance that aligns closely with the maximum recommendation without exceeding it is thus 270 inches. Therefore, this choice accurately captures the necessary distance limitation for optimal viewing.

This understanding places the calculated distance in practical context, demonstrating why 270 inches is an appropriate and established viewing distance for a 4K display with 90 inches of image height. Options that suggest shorter distances do not account for the full clarity and detail benefits that 4K technology provides at
