Hi! I am trying to connect two Arcade Monitors with Ultimarcs VideoAmp to ONE Videocard. My problem is quite simple. Neither my NVidia card, nor my ATI card detect a monitor on the DVI port. It DOES work if I use a normal VGA Monitor, so I suppose I need to connect more than just R, G, B, H-, V-Sync and GND. Anyone know which pins i need to connect? I've heard something about Pin 11 connected to GND, but didn't try that one yet. |

Standard Arcade Monitors are 125khz Pc Monitors Svga/Vga are 31khz+ First you need to drive your Video Card to output the 15khz before you see anything on the Standard Arcade Monitor. Or the easy way (a bit of $$ involve), get yourself an Arcade VGA Video Card. |

Thanks for your reply. Yeah, my cards output 15KHz on both heads. Also, an ArcadeVGA won't output 15KHz on the DVI Port :) Like I said, my only problem is that the cards don't "sense" a monitor with the J-PAC or the VideoAmp. Multiple Monitors should be visible in your video cards settings, i.e. the Catalyst Control Center. |

I'm assuming your card only has DVI connections. Is there a VGA adapter/converter used ? If so, some Arcade monitors need the V/H sync separated so, you need the open the half moon shape on the AMP and wire the V/H synch separately. |

Hi. My cards have one VGA, one DVI and a TV-Out. Yeah, there is a DVI-VGA Adapter used, thats not the problem. As soon as I plug a normal VGA Monitor in the system say "Hey! Theres a second monitor". But it doesn't with the J-PAC or the VideoAmp. Also, both heads are active on boot, and the DVI disables as soon as Windows loads up. The ATI card does not detect a Monitor on the VGA connecter either, but I guess they leave VGA enabled as a fallback. |
