The raction time is 8ms but when you are a programmer and look more
than about 4-5 h on a flickering monitor....for me its not
satisfactory. This is my first experience with lcd monitors and I
thougt why I can'r change this values. If so..no problem. But what
about the flickering and the diffuse letters ? maybe I don't know if
this is subjective to me..

Yes but YAST has not my monitor only the 'vesa - 1024x768@60 Hz' I try
to change to 70 Hz and I get 'out of range' an nothing works..;-
