Hi everbody, I wanna implement VGA core at 1024x768x75Hz (15" LCD Monitor) on Spartan3E starter kit. I have got a few question. I have tried to find some detialed documents for VGA timing But I can't. There are 640x480 and 800x600 but there is no document for more resolution and refresh rate.
- Front porch time, back porch time, and sync pulse times are same at every resolution (I think it's standard because VGA cards can change resulation and refresh rate for every value and every monitor??? But There are different values for 640x480 and 800x600 on the documents???)
- What is hsync and vsync polarisation? What must I do if it's negative or positive? (invert the sync signal???) Why it is different for different resolution?
- Any body can give me timing values or recommend any source? ( I can't a right document on the Vesa web page)
Thanks
