I am not being rude, but this question has been asked a million times already. Search for "Front Porch" in this thread, for example, you'll stumble upon Spartan F8's posts where he has given excruciating detail into what he's done to reduce the pixel clock.
Even the reply above mine has mentioned looking a few pages back to find the same posts I'm leading you to.
And you've just described a side effect which solution has been covered several times already...lower the pixel clock by adjusting other settings.
