Thank you all for the response, much appreciated
What connection are you using?
Which monitor? 2930 or 2931? 2931 has the OSD.
2931 ( auto ) , tried both direct db15/vga input, and RGBS through the sega jamma/jva io
I get a dull image from certain systems on my Tri-sync CRT monitor's if I don't change the .75ohm / 1kohm switch on the remote board. Oddly, I always have to turn the brightness way down for regular PC output even when the monitor is set for consumer rgb.
My PS2 has the opposite problem - it's always dull on my arcade monitors so I have to use an RGB booster. I got mine from Ultimarc. It's the product they sell to use use consumer consoles on old CGA arcade monitors to avoid a dull image. It's probably cheaper than buying the official Sega rgb amplifier anyway:

This is the Ultimarc one I use:

yeah I'm familiar with remote board dip switch on the 2930, but this monitor it's an auto.
wow, the VS kit twin out pcb is getting as expensive as what I paid for a whole vs kit years ago.
I was wondering about an rgb booster , something that brings it up 0-0.7v p2p, nice to know about the ultimarc one
Got two naomis, and two blast cities. all combinations results in a dim / dull screen. ( like compared to a my hypserspin pc )
5v is good
went through all the possible chassis & remote board adjustments...
is there some known component that commonly causes this in a naomi ?
See if the ground blew on the filter board's RGB. Also, check the RGB dac on the motherboard to see if it's getting hot.
ahhh dude you lose me as usual lol > ground blew
like one of the emi filters ? how do I check that ?
> RGB dac
I know it's small, but, any code or number to help ID the dac ?
