I have a CRT monitor I pulled from a Megatouch. It's a VGA monitor.

My goal is to use the monitor in an arcade game by using one of the GBS-8200 CGA to VGA converter cards. But I can't get it to display properly.

I hooked the converter up to different monitors in different ways, but the Megatouch CRT doesn't want to play nice. Here's what I've tried:

First, to verify that both worked properly, I ran a 60-in-1 board into a VGA converter card (via the RGB harness on the JAMMA connector as well as the harness that came with the converter card) then ran that to an LCD monitor via VGA output of the converter card and it displayed perfectly in both instances.

So that tells me that both the 60-in-1 and the converter card work.

Then, to verify that the CRT monitor worked, I hooked it directly to the 60-in-1 via the VGA output on that board and it also displayed perfectly.

But when I hook the 60-in-1 to the VGC converter card then hook up the CRT via the VGA output on the converter, I get jittery, sometimes scrambled, multiple layered images of the display. I posted a pic below.

To be clear, I'm only using the 60-in-1 to test the setup. It's not the game I want to use the monitor with. I'm still trying to repair that game board and want to get this setup working so I can test the game board before installing everything.

Anyone have any idea what may the cause?

To be sure, did you switch the 60-in-1 card to 15k mode? I forget which one of the 4 dips it is, but it toggles between VGA and 15k.
 
Yes, pin 2 was switched. When I hook up the LCD monitor, I can get it working. The configuration only has a problem when it's hooked up to the CRT. Yet the CRT works fine when hooked up to the VGA output of the 60-in-1.

It seems almost certain that the problem is with the converter card. I have two identical cards and they both are doing the same thing.

Maybe the 8200 series doesn't like to play with CRT's... I've actually ordered an 8220 series, maybe that will work...
