footrest to maintain the correct alignment for your legs.

below the horizontal. If the monitor has a tilt and swivel base,
you can adjust the position of the screen for the best viewing
angle.
Sit about an arm's length or more away from the monitor. The
most comfortable viewing distance depends on the size of the
screen characters and your ability to focus on the display.
Adjust the monitor's brightness and contrast controls to
maximize image clarity, and keep the screen clean.

level. This reduces neck strain and makes it easier for your eyes
to move back and forth between the document and the screen.
