Why the PIXCLK frequency is not consistant ?

Hi,

I am using iMX51 connected a WVGA LCD.

I measured the PIXCLK frequency and it is a variant waveform. It means that the high time on the clock pulse varies in a scope. As we know that Pixel clock frequency is directly related with the frame refresh rate. But I don't know why?
