Headache with Benq TH671ST

I’m going to second this. My guess is you’re picking up on the rainbow effect due to the “2X” color wheel. The RGBRGB HT2150ST has an effective “4X” wheel for 60Hz content and an effective “5X” wheel for 24Hz film. It will have a far less chance of displaying RBE for the vast majority of people.
The other possibility is you have the projector set too bright. An overly bright image can also cause eye strain and headaches. Try backing off the lamp power or changing picture modes and see if that helps.
What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...
