If I want to have a resolution of X * Y pixels, updating in frequency f. How do I calculate the pixel clock speed?
Example: 1280 x 1024 @ 85Hz usually have a pixel clock of 157.5 MHz, but how do I calculate the needed pixel clock?
Need to know to select DAC and DSP.
Edit: Usually the Front porch is: 16 pixels 1 line, Synch width: 144 pixels 3 lines. So this is a total of 1688 x 1066 @ 85Hz. But, still the pixel clock formula should be the same regardless of the extra lines and pixels.
