"missing backlight between frames......"

This sounds like it's DOUBLE strobing.
I can make it do that on mine if I use a 1179 vertical total at 60hz refresh rate (the only way I can make lightboost activate at 60hz)
(it then strobes at 120hz instead of 60hz, missing a frame every cycle).

What vertical total have you tried for lightboost?
Lightboost 100hz is 1138 vertical total
110 is 1143
120 is 1149
60hz will double strobe at 1179 VT (otherwise it won't strobe at all).

What refresh rate are you using?

Can you try a higher vertical total value at 120hz? (you can edit the custom resolution in ToastyX's CRU). You should be able to use up to an 1180 vertical total before the monitor goes out of range. Some VT's may fail to activate lightboost; in that case try a value of +5 higher.
