Perfect. It should be sufficient to set the value for "Vertical total" from 1068
to 1073. All other timing values are identical to what i have except the pixel clock:
i have 328.80MHz where your setup shows only 273.45MHz - that's pretty low!
Even in your current setup, it should be 5376*1068*57 = 327.26MHz!
Looks like that there is yet another problem ...
