I don't think it is a SYNC issue.
I have a PS1 connected directly to the BVM using a RGB cable, and SCART->BNC adaptor from retrogamingcables. No switchers. I tried difirent RGB cables, and a PS2 with no effect. I don't have the 75 ohm terminators yet, but i connected the BVM to my PVM 20L2 wich has automatic termination with BNC cables. The image on the PVM is still as a rock, but there is always a noticeble shake on the BVM. Even when there is no signal it's still there.
I found a topic on this site, started by Carthik describing the same issue, but on the 20E1U (I didn't see it when I posted mine). He even recorded a video showing the problem. Here's the link to the video:https://www.youtube.com/watch?v=UBIfJfV ... e=youtu.be
The thing is, this is exactly the same Issue I'm having. Do anyone know what could be the cause of this kind of shaking? And is there a way to fix this?
