Hello again,

I think that the next step, to debug the system, is to use the TPG and go step by step backward.

Check what happen if you place a 800x600 TPG before the clipper?

Then continue to the next step, put it before the frame buffer. This can give you better understanding if the frame buffer is working.

Regarding input clock and output clock:

If you have Frame buffer with adding and dropping capabilities the clocks do not need to be the same and also there is no need for any relationship between them (in other words – no need for synchronization between them).

Good Luck!
