vga to rgbhv converters

[NeoMagicWarrior]

hey, pretty new to the cabinet building scene... and in the process of finding a "donor cabinet"

found a nice MVS-1-25 and thinking about buying it. since it has a standard arcade monitor and the cpu i have has a nice graphics card as is, i was looking into vga to rgbhv converters...

anyone ever use one? if so, how was the quality / ease of use?

Use the "soft 15khz" and quickres programs. That gets you to std res land. Then you need a VGA breakout cable to have seperate R/G/B and H/V sync wires. They usually come with BNC connectors, and I'd suggest making a cable to go from BNC females to individual wires and then to the Molex header connector the monitor wants to see. I made a cable by hacking off the BNC ends and that was not the greatest idea. The center conductor in each shielded cable is pretty thin and frail....I already broke one off and had to fix it.

The only other thing you may need is a RGB video amp, and thats only if the video inputs of your monitor want to see TTL level signals. You'll know if they are not strong enough because it will be hard to get a good bright pix and maintain acceptable black level. I just built one, but there are pre made units available from Ultimarc and the like.

"RGB" and "RGBHV" is basically the same thing. just a different hookup is all.

all you have to do is match the output of your card to the monitor's capabilities.

soft15k is a simple way to achieve this. it will give you that low resolution frequency needed for older standard and medium resolution monitors. I personally haven't had to use soft15k, I've been fortunate enough to have access to VGA monitors when needed. but should the need arise, this would probably be my first choice.
