Normally I wouldn't have an issue with this thing because it works well with all my Standard Resolution games. BUT it hates working with Medium Resolution games PERIOD!
I've had this thing for maybe like 2-3 years now, I have no other problems getting it to work and such.

I've tried multiple ways to link it to the outboard video on both my Virtual On and Virtua Fighter setups. All I get from it is "No Signal." I've gotten to work once with my Virtual On boardset, but omg the colors were soooooo horrible and washed out. There was no crossed or shorted wires, I tried my best to adjust the picture/color quality on both the converter board and the VGA monitor I had it plugged into. And yes, I know that the color codes on the sync and ground are different on those SEGA harnesses. White is Ground and the Blue White Striped is Sync, but it simply refuses to work 99.9% of the time.

I've got the 5v DC it needs to run, there is nothing below it to short solder points, I'm using the 5 pin RGB hookup for the CGA/EGA games, and the input is set to "RGBS," the other inputs like RGBHV is for the High Resolution games, and of course everbody knows what YPbBr is for.

I'm not sure if anyone can help me with this, but I'd sure like a solution! LOL before I yank my hair out.

P.S. the Virtual On boardset was tested in one of my cabinets and works fine
 
I wouldn't mind this if I had a Medium Resolution Chassis and Yoke for my naked 25" Tube, but all I got is standard resolution monitors.
