i found that gamma gives me a bit washed out colors.
but reducing my brightness by 5 helped this effect.
they are now:
sharpness: 0 or 50
color space: native
skin tone: -2
edge enhancement: off
color temp: normal
notice color temp is on normal here.
i use fim mode now because i noticed global dimming is obviously turned off there (or lower) compared to the same settings in standard mode.
firmware is 1010
i will still have to experiment with finding the best compromise between blacks, gamma and brghtness though. but it looks rather good now.
(except 2 stuck pixels i found)
regarding the settings posted before mine:
what strikes me more about those is color 50 with a skintone of +2?
this gives red faces on my tv.
so im still hoping for more calibrated results. if someone could try to get tweaktv to calibrate a 750 please :-)
im also wondering why so many tv-magazines do not test the 750. i think they believe its identical to the 650, which is not true (the 650 settings look awful on my set).
