The video chipset or GPU (video card) itself can not be adjusted. Any adjustments that are made are made to the monitor which is in turn controlled by the video card.

Generally, headaches are caused by an improper refresh rate, however, with today's modern LCD displays, the refresh rate is usually set at 60Hz. Older CRT monitor refresh rates could go much higher.

I have read that some folks who suffer from headaches while sitting in front of a computer monitor have been able to reduce the occurrence of headaches by wearing computer glasses. You might look into trying that. Good computer glasses are not those you pay $20 for at Office Depot, however. Be sure to consult your Optometrist or Ophthalmologist first before investing in computer glasses.
