For me the revolution was to get a rather expensive monitor [1] with a great reader mode that lessen the flicker considerably. When I game with it and I turn off reader mode my eyes really feel the difference even though I spend way less time gaming than working.
I wonder if OLEDs will be even better since they shouldn't flicker during productivity (from what I read at least).
[1] was one of the LG ultrawide 34" but it was a few years ago and can't find it anymore.
