Please excuse me for my ignorance, but the hotline reply makes limited
sense to me. There are two reasons:
1. The m4-035-9 workstation is not located near the back wall.
It is located in the center of the room, with two nearby workstations
also in the center of the room running at 75Hz refresh rate.
2. If there are electrical 60Hz oscillations in the electrical circuitry
of the back wall, then anything set at 60Hz *will* be flickering and jumping,
while monitors set at 75Hz will not be misbehaving.
As a matter of fact, the eye fatigue I observed was primarily to
flickering on 60Hz workstation, while 75Hz workstations were not flickering.
Thanks,
Mike Khusid

The reason why some of the workstation are set to 60hz is because there close
to
the back wall and setting them to 60hz is so they don't jump and flicker due
to
the electrical conduite on that back wall. If they hurt your eyes use a
workstation far away from that back wall.

SGI workstation m4-035-9 is running at 60Hz refresh
rate while all nearby SGIs run at 75Hz refresh rate.
60Hz rate really hurt the eyes.
