It doesn't work with Cyclone II, you have to sync on 25.0 MHz. Any reasons to assume, that your display won't accept it?

Hi

previously I was running PLL in normal mode, but after suggestion to use PLL in sync mode, I have compile it in this mode. But again display showing the same problem.(display accept the output but at the output whole picture break up into 4 segments.)

I have selected the resolution of the display at 640x480.

Thank You
