We have an existing design that uses an AD9889B. We are only running 720p60 video. We have hooked this up to quite a few different monitors without any problems but recently we connected it to other equipment and the equipment does not recognize it. So the output works with some equipment but not others. We do not have an HDMI Analyzer of any sort so I thought I'd start by posting here to see if anyone has seen this before. I did go through the timing registers and that all looks correct. Any thoughts?
