Query: Brown Lines

I've ran into the same problems of the brown lines. I have now gone through THREE replacement monitors (at no cost except the first replacement was $40). The third one just started showing lines a week after I put it to use. Samsung claims it is my video card, however, I have used my video card with another monitor (another brand) and it doesn't show the lines. In addition, I have attached the Samsung to another computer and the same lines appear. I don't think that it is my video card.
