Connecting a Mac to a Sony PVM

[Svovl]

I recently got my hands on a Sony PVM 20L4.
It would be great to be able to use it with games from my Mac.

Some time ago I bought an Ultimate SCART Adapter (http://www.arcadeforge.de/index.php?cPa ... s66ajpqjn4) and a 15khz vga dongle from Arcade Forge in Germany.

However, I haven't been able to find a way to set a proper resolution for the screen.

Have any of you had experience connecting a Mac to a 15khz monitor?

Cheers

Yeah, I have the dongle as well and never managed to get 15khz to work.

Doing it within OSX is impossible to begin with I believe. So I installed XP via bootcamp for the sole purpose of enabling 15khz via the soft 15khz tool, but I never managed to get that to work.

I think perhaps the onboard graphics hardware in my ~2010 Mac Mini is just not capable of putting out a 15khz signal or something.

If you manage to get it to work I'd be intetested in knowing the details.

You might want to take a look at SwitchrezX http://www.macupdate.com/app/mac/8355/switchresx . I think it will let you change the settings manually for your video card. If it doesn't check one of the Similar software options they suggest on the page. I think there was one I found along time ago to make a old PPC mac work with a arcade monitor.
Good luck.

The Mac I am trying to use is a 2010 Macbook Pro, and I think you are right that the graphics card isn't capable of a 15khz signal!
Perhaps the solution is to get my hands on a Scan Converter like an Extron Emotia?

If you still got a VGA output, then this is certainly the easiest way. If you can live with 480i instead of 240p, you don't have to for a hard to find Emotia, you can get any Extron VSC unit instead.

I've got VGA out. I'm going to try my luck finding an Emotia. There are some on eBay, unfortunately without power supply.

Buying a device as big as the emotia just for 15khz support is a clumsy solution.

With all these emulator handhelds showing up these days one would think someone could do the same thing but designed around external displays and controllers.

A tiny elegant box designed to just run MAME, complete with internal flash storage, USB connector for your standard fare USB arcade controller or what have you and video out capable of anything from 15khz to 1080p.

Someone kickstart an elegant solution that just works like that and I am ready to invest.
