This is very pseudo-scientific; and not just because of the unqualified health complaints. So to meet psuedo-science with pseudo-science: * I'm only talking about straight forwards adjacent alignment of screens. * Having the head not-facing forwards causes physical accomodations, like twisting and side-slouching, which over time develop into pain and other problems. * Any large screen is subdivided into multiple work areas, either user-intentionally by windowing, or unintentionally by formatting (ie. Hacker News' text box is on the upper left of the screen). These areas should be those considered, and not the whole screen, and henceforth shall be considered "screens" in their own right. * It is OK to have some screen acreage outside the central FOV, so long as either: a. it is glanced at, and not worked on with the body facing another direction; or b. the user turns their entire setup to use the screen. * An ultrawide monitor can be modelled as two, or three screens, depending on windowing modes. * In a two screen setup, many people centre their body on the position between the screens. This causes all areas of interest to require rotations. * In a three screen setup, there is a central "primary" screen and two "secondary" screens for glancing at. If the body position is able to be rotated it is possible to switch primary and secondary screens; the main concern is movement of keyboard and mouse. * Rotating the body is hard, a traditional keyboard often results in one handed use that in turn results in side-slouching, whilst a split keyboard remedies the slouch by centering the body - preventing rotation, forcing the rotation to come from the desk area. * In a two screen setup, if one screen is centred and the other screen is off centre then there is one primary work screen and one secondary screen. (ie. "missing third screen"). * An ultrawide monitor, modelled as two or three screens, needs accomocdations. Either off-centering the monitor or providing the ability to rotate the body.
