Thanks for your reply. I have just gone over the manual. Just to double confirm:

the horizontal data flow is: H front porch -> H Sync -> H back porch -> pixel data, and then repeat itself.

h_sync is asserted during "H Sync" only; and vid_datavalid is asserted during "pixel data" only. Is that correct?

Thanks very much!

vid_h_sync is only referring to the horizontal synchronization period and not the blanking period.
