Forgot to add some english text. I am working on a Nios II Embedded Evaluation Kit CycloneIII Edition with terasiC Expansionboard.

From the NIOS_Evaluation_Kit_v8.0 video example I have tried to build a very small test Pattern Generator to Touch LCD example. So iI have got some output an the LCD, but it is flickering very much.

Why doesn't it work to connect the TPG directly to the LCD? Have I got to implement the hole video pipeline and feed the LCD from DDR memory everytime?

I have attached my small SOPC design to the first thread.

Thanks for your help.
