"Pitch" is actually a useful rotation. Displays should be placed as far away as practical, with their top edge roughly at eye level, and tilted so that the bottom of the display is closer to the body than the top. Eyes have an easier time both focusing and converging closer in the bottom part of the field of view. Viewers should sit up, with their backs and necks straight and plumb, and look around at different parts of the display by moving the eyes rather than tilting the head.

The top edge should only be at eye level of the screen is small enough. With a large 4k you want your eyes around the center because everything above that is the "upper monitor"

  For comfort you do not want to be looking substantially upward or tilting your head back. It’s much better for your eyes to put the display lower and look down (by swiveling your eyes, not your whole head) for the bottom part instead. For typing it works well with a large display to put the bottom of the display barely above the desk, push it back as far as you can (constrained by your workspace) and tilt it backwards near the top, and position the desk/chair so that the desktop is at roughly waist height (let your upper arms dangle loosely at your sides with your elbows close to the body and bent about 90°, keep your wrists straight, and position your fingertips at the tops of the keys of a keyboard resting on the desk). I have a 27" display ("5K") and the top ends up just slightly below eye level. If you have a 40" display or something the top will probably end up a bit above eye level.

    Or just zoom in (increase font size) enough so that you do not need to sqeeze/focus in order to read.

      Your eyes need to focus and converge on the display surface irrespective of the distance or orientation of the display and irrespective of the font size. But as a general rule, the further the display surface the less your eye muscles need to work. So if you can put your display 3m away from your eyes that is better than putting it 30cm away. On my desk, about 90cm from my face is the furthest I can manage, but if you have more space in your work room, by all means put the display significantly further than that.

> with their top edge roughly at eye level I'd heard that this advice has changed, and that the centre of the screen being roughly at eye level is recommended. Though maybe that was wrong?

  There is a ton of terrible advice out there, including from official standards organizations. Office ergonomics is a mess, with widespread normalization of injury-causing practices, and a lot of poorly designed/implemented research uninformed by any understanding of human anatomy. If you find some particular screen placement personally comfortable though, go for it. Keyboard design and use is generally a much bigger problem.
