scaler problem

Hi, I have another problem about scaler, it's right that adding a control port to scaler makes the input resolution changable, but some resolution doesn't work. My data path is listed below. Clo...

Hi All,

Just wanted to provide an update. It appears as if the logical function of the video path is good, e.g. I can trace a pixel through the system and have it come out of the CVO when doing the 800x600 -> 1600x1200 scaling. The external device that translates the CVO (FPGA Output) to a 1600x1200 capable monitor seems to be seeing something different in this particular scaling mode, although at this time I cannot determine exactly what that is signal integrity wise. I suspect this may be because of FPGA timing problems, or, an output drive problem.

Thanks,

Mike
