Are you still having problems with this?

A quick look at the .qsf you posted shows a conflict between the 'hsync_p' & 'hsync_n' signals. One is 1.8V, the other 2.5V.

I think you should be generating hsync as a differential signal. However, your qsf shows different single ended I/O standards for each half of the pair.

If you still need help let me know.

Happy New Year,
