I need to be able to have the ADV7441A free run with a video standard I've setup even if there is valid video on its inputs. I'm having some trouble getting this to work consistently. It works without any problems if I have no video, but if there is video (especially on the HDMI/DVI inputs), then sometimes the ADV7441A does not output a VS. It appears to be somewhat intermittent although it seems to work best if I disable incoming video. Disabling incoming video is not an acceptable method because I still want to use the ADV7441A to tell me if there is video on its inputs. Any suggestions?
