It's a bit different for 120hz, but one thing I noticed when you "invert" the strobe phase, at 100hz, 059 strobe phase --which gives you the lowest persistence (0.167ms with a VT 1500 tweak, regardless of strobe duty/intensity setting), one point of strobe phase before the backlight shuts off, has a difference of exactly ONE PIXEL of crosstalk position at the top of the screen higher up, compared to strobe phase (area) 000, with strobe duty 001 on Z (or intensity 25 on 2430T). At area 59, the top crosstalk is fully and 100% completely off the screen with NO hint of the beginning of the "black" field (if you notice, the black field is when the position of the images starts to get 'shifted' to the right; you can see that if you raise or lower the strobe phase). But at area 0 (strobe phase 000) combined with strobe duty 001 (which is also 0.167ms persistence assuming a VT tweak), you can see the VERY FIRST pixel of crosstalk strobe pulse settling errors at the top of the screen. Only the first pixel, though. So there's just 1 pixel of difference, between phase=59/intensity=irrelevant as its forced to lowest persistence, vs strobe phase 000, strobe duty 001. But at strobe phase 058 and as you go lower (at 120hz this starts at 050 and you go downwards), you see the top look perfect as the bottom crosstalk starts moving slowly up.
At area 059 at 110 hz (50 at 120hz), you can't use duty (intensity) adjustments, since as I explained, area 058 only allows 0.167 and 0.333ms persistence for duty, and area 057 only allows 0.167, 0.333, and 0.5 ms, and so on), so you have to lower the area value to free up more intensity adjustments. So you can get the top or bottom of the screen to your liking, depending on the game you are playing.
(that corresponds to 050, 049 and 048 area at 120hz, etc).
*edit* again
Your 100 hz area 55 intensity 21 should correspond to 0.835 ms persistence, which is equal to strobe duty 005 and strobe phase 055 on mine (anything above 0.835ms gets ignored)
I think the highest usable setting that isn't too dim is area/phase 056, which gives strobe duty=4 0.668 ms (maximum), or 0.500, 0.333 or 0.167ms as the values you can change. Looks like these settings still are valid for XL2430T. (which you can use on yours as intensity 25, 24, 23 or 22, I'm assuming). That's 0.668ms is still a bit too dark for my liking, so I limit myself to 055 area (0.835ms maximum persistence).
