If you are viewing in very low or no room light scenarios, have you guys tried some sort of temporary back light just to see if that helps reduce your eyestrain while viewing in the dark? A small lamp centered in back or perhaps a couple candles. Also, have you done any sort of calibration to your panels yet, especially one more suited for low or no ambient light viewing? If you've upgraded from a smaller size, and you have the panel set to a default sizzling-bright output, relatively speaking, this extreme brightness in a darkened room might be triggering your discomfort.
