It's realy nice test, man!
Interestingly, all differences are multiple of 10 ms. That meens you run the test at 100Hz, right? Native frequency for LCD monitors is 60 Hz, and AFAIK even when they report 75 Hz they actually work @60Hz and interpolate signal from 75 to 60 Hz. That introduces some uneven lags because 60 and 75 are aliquant.
So I conclude, that the monitor seems to have 2 frames (32ms) lag in "normal" mode and 3 frames (48ms) in "game" mode.
That you for the report!
