Just be glad you got it working at 75 Hz. Anything above 60 Hz will eliminate
visual flicker for most people, and anything above 70 Hz will eliminate flicker
for all people. No human has an eye with a 70 Hz plus scan rate.

You don't want to use this 87 Hz mode. It is interlaced, hence the (I). You
will notice interline twitter and likely interlace flicker using this mode and
it will be hard on your eyes. See: http://en.wikipedia.org/wiki/Interlace
