MAMEWorld Forums - Ultimarc - needing some ArcadeVGA + Mame setup clarification

Hi everyone, I read through everything on here regarding ArcadeVGA and I'm not sure I completely grasp the whole thing, so before I go spending cash on a monitor, arcadeVGA and new PC to build for it I would really appreciate some clarification to know it'll do what I want it to do.

So my main goal is to get MAME working at a level where I get the least amount of input lag without any screen tearing. I just want the games to run at their native framerates and to have as close to real arcade controller response as possible.

From what I understand ArcadeVGA will output 15khz at native game resolutions to a 15khz CRT monitor, and the resolutions/refresh rate will only work on a monitor that supports them. Am I wrong to assume that the ArcadeVGA will not turn any PC CRT (like a 31khz monitor) into a 15khz display by forcing the signal into it?

Also, would ArcadeVGA (or any hacked ATI GPU) running into a 31khz CRT give me proper input response and no screen tearing/smooth scroling?

And finally if I get a VGA monitor that can sync at 15khz does that mean everything should work correctly? Or does it strictly have to be an RGB/Scart/Arcade monitor?

Thanks so much for any help.
