ok so update i installed my moniter drivers and its still happening, yes it does happen when changeing resolution but even when i am just sitting here without changing resolution on the web and it randomly starts flickering. called dell told them about the problem they simply had me do the moniter self test and they said everything was fine. i heard of someone with the same problem with an ati card and they said they reduced their dvi frequency, where can i do this with NVIDIA Forceware.
