I recently bought a naomi gd rom set up with a sega I/O and when I started the system it seemed like the picture was far too bright. When I checked the color settings in the test menu there was a large amount of color bleeding and the black its more of a grey color.

I had a spare naomi mother board and swapped them just in case but it did not seem to make a difference. I also put one of my cps2 boards in and it looked fine. Last thing I tried was to adjust the brightness on the back of the monitor I believe its called the flyback? didnt really seem to help with the color problem. Could this be related to the separate power supply that came with the system. The machine I am running this on is a Super Neo 29 if that helps any. :scratch:

Could have something to do with the RGB drives from the mobo or a ground issue,; try adding an additional video ground connection between the game board and monitor.
