one opinion...

4. Place the top line of the screen at or slightly (0-30 degrees) below eye level.
According to ergonomics expert and professor Dr. Alan Hedge, “When you are seated comfortably, a user’s eyes should be in line with a point on the screen about 2-3″ below the top of the monitor casing (not the screen). Sit back in your chair at an angle of around 100-110 degrees (i.e. slight recline) and hold your right arm out horizontally, your middle finger should almost touch the center of the screen. From that starting position you can then make minor changes to screen height and angle to suit. Research shows the center of the monitor should be about 17-18 degrees below horizontal for optimal viewing, and this is where it will be if you follow the simple arm extension/finger pointing tip. You actually see more visual field below the horizon than above this (look down a corridor and you’ll see more of the floor than the ceiling), so at this position the user should comfortably be able to see more of the screen. If the monitor is too low, you will crane their neck forwards, if it’s too high you’ll tilt their head backwards and end up with neck/shoulder pain.”

fwiw, i use a 24" screen vertically over my main 32" monitor. the 24" is mostly for plugins. i sit back at about 15 degrees from vertical with the screen at a slightly less angle toward me. i have a high backed chair that comfortably supports my head and neck.
