12.1.1.3.1-5 Viewing of Multiple Display Devices

When multiple, large display devices are used, the normal work areas of each user should be within the acceptable off-centerline viewing area of each large display that each user must view.

Additional Information: If the large display devices are adjacent to each other, they should be angled toward each other so the acceptable off-centerline viewing areas of the displays overlap. If the operators’ tasks require them to work at multiple locations in the control room, the acceptable viewing area should be maximized by angling the display surfaces toward each other so that the acceptable off-centerline viewing areas of each display device coincide to the greatest extent possible.2090
