Naomi to RGB Scart

Post by Beaps »

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: http://members.optusnet.com.au/eviltim/ ... escart.htm

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?
