DE0 old problem Pixelbuffer and SDRAM

Hi,

thanks for your reply.

The hole TFT-monitor is full of stripes and some colourfull pixels.(Picture)

Do you mean I should use an extra PLL and increase the clock for the SDRAM?

I looked in the data-sheet of the sdram and created an excel-file to calculate the phase delay. Maybe I can use the Alt avalon pll to realize it... I will test it.
