Hi All,
I am trying to connect my Naomi system to my BVM via RGB Scart. I have flicked the jumper to set it to 15khz but I getting like a vibrating interlaced image.
Here is how I got it setup
When I go into test mode I get this
Is there another dip switch I need to switch. Currently I have 1UP the other 3DOWN.
Any help would be appreciated

it seems it's having a problem with sync.
Take a look at this:

With most game consoles, the hook up is not a simple straight wire. You need to match impedance (75ohm) and add caps for DC bias.

Have you set the naomi to low-res output?
This looks like trying to show a 31k picture on a 15k screen. The BVM is 15k right?
