I am having a one year old Dell U24410. And connect the same with my system. I am using the same from last twelve months and it has served me well but from last few months i am not getting proper visual and yesterday it has crossed all limits and literally flickered. It happens once or twice in the fifteen minutes interval. I don't know why it is doing so. It looks similar to TV when we remove the cable input. Only black and white tiny dots are visible to me when the screen flickers. Now I am not able fix this issue and badly needs a help.
