I do not blame anyone, I know you all want to help.
I tried to take a picture and take a video, but unfortunately 30 frame per second can't catch it. Everything looks nice.
I will try to explain again. In compare with kernel up to 2.6.27 (because I used Ubuntu, Mandriva), 2.6.33 looks:more brighter, may be more contrast, especially white, it is definitely more brighter although I stated xgamma 0.75. But biggest problem is that colors of the picture are not solid, stable - they are somehow blinking or flickering. Sometime I think may be back lights of LCD panel works different. And after hour or two eyes start notice it, it is looks like colors is not constant, they always changes, little bit but they are "playing".
It is very noticeable if I log into different TTY (not graphical) and just start "mc" - it present for eyes.
It is impossible to record, sorry.

Thanks for help.
