Side note, I have been using composite sync with RGB TO YUV Atlona board with no issues. Slight jail bars but not bad (I haven't done Steve's fix yet).
Using a RGB TO HDMI for video capture looks terrible. Now I realize upping to HDMI is going to impact PQ a little and I'm ok with that, but the signal has a lot of artifacts. I'm thinking the Rgb to HDMI box does not like composite sync.
At first I thought maybe I need a new Amp, but perhaps this is a composite sync issue? Thoughts on what to try here? I have seen this same RGB to HDMI box used on a Genesis and the signal looks flawless,
But on Duo it looks like balls. I know they have different resolutions, but I'm seeing a lot of dot crawl witch is why I am suspecting the sync line being the issue.
