Again, just to see if it could be done. Its [thread=142629]256[/thread]/[thread=142764]400[/thread] pixels counterparts fetch the pixels while displaying them (just before in fact). This one needs at least double buffer mode to function but can also use multiple buffers (>2).
Signal timing is 640x480@60Hz, any colour value is acceptable (video h/w doesn't control sync lines during visible lines).
